The 5.7 HEMI in your Ram 1500 is a hungry V8, and the oil filter is one of the cheapest pieces of insurance you can buy for it. This engine uses the larger MO-339 style filter footprint, and getting the right one matters because the HEMI runs a hemispherical combustion design that loads the oil with heat and contaminants under towing and stop-and-go driving. A weak filter media or a sloppy anti-drainback valve shows up fast as dry-start rattle on a cold morning.
We looked at fitment on the 2009 to current Ram 1500 5.7L, filtration efficiency, bypass valve calibration, and how the gasket seals after a few heat cycles. Below are the seven filters we trust on this engine, ranked best first. Every one of them is a genuine fit for the HEMI thread and gasket spec, so you can choose based on how long you stretch your oil changes and whether you tow.

1. Mopar MO-339 Oil Filter: Best Overall
When the goal is matching exactly what Chrysler engineered for the 5.7 HEMI, the Mopar MO-339 is the safe answer. It carries the correct bypass valve pressure setting so your oil pump and VVT system see the flow they expect, and the silicone anti-drainback valve does a better job of keeping the filter primed overnight than the nitrile valves you find in cheaper cans. On our test truck the cold-start lifter tick that some aftermarket filters allow simply was not there with the Mopar in place.
The honest weakness is that this is a no-frills filter. There is no anti-slip coating, no drain plug, and no nut welded to the base, so installation and removal are the same knuckle-busting job they have always been on the HEMI. You are paying for OE engineering and consistency, not convenience features. If you never want to think about whether your filter matches spec, this is the one, but enthusiasts who like extras will look further down the list.
- Genuine Mopar OE specification with correct bypass valve calibration for the HEMI
- Strong silicone anti-drainback valve that holds oil for clean cold starts
- Tall MO-339 body gives extra media area over the small 90 size filter
Pros: Exact OE fit and pressure spec, zero guesswork; Silicone drainback valve resists heat better than nitrile; Proven reliability over hundreds of thousands of HEMI miles
Cons: No drain or grip features, it is a plain OE can; Often only sold through dealers or select sellers
2. K&N HP-2009 Performance Oil Filter: Best for Towing
If you tow a trailer or boat with your Ram, the K&N HP-2009 is built for the heat and pressure that come with it. The standout feature is the 1-inch hex nut welded to the end of the can, which turns the HEMI filter from a slippery, oily fight into a quick wrench job. The canister is noticeably heavier gauge than a budget filter, so it shrugs off the high oil pressure spikes the HEMI generates when cold and working hard.
Where it gives ground is absolute filtration. K&N tunes this filter for flow, which is exactly what you want when the engine is under load, but that means the media is not chasing the tightest micron rating on this list. For a daily commuter on long oil intervals, a pure long-life filter captures finer particles. For a working truck that pulls weight and gets serviced on schedule, though, the flow and the welded nut make it our towing favorite.
- Welded 1-inch nut on the base for fast wrench-on, wrench-off service
- Heavy gauge canister resists deformation under high oil pressure
- High-flow media designed to keep up with the HEMI under load
Pros: The welded nut makes removal genuinely easy on the tight HEMI; Thick can and rolled seam feel built for heavy duty use; Strong flow rate suits towing and spirited driving
Cons: Filtration efficiency trails a dedicated long-life synthetic filter; Bulkier than stock, watch clearance during install
3. WIX 57060 Oil Filter: Best Build Quality
WIX has a reputation among truck owners for building filters that feel like they belong on heavy equipment, and the 57060 lives up to that on the HEMI. Cut one open and you find metal end caps instead of cardboard, a thick steel base plate that stays flat under pressure, and a silicone anti-drainback valve that keeps oil in the filter where it belongs overnight. This is the filter to grab if you have ever had a cheap can weep oil from a warped base.
The trade-off is purely cosmetic and ergonomic. WIX does not put a nut or grip texture on this filter, so removal on the cramped HEMI is the usual oily struggle with a cap-style wrench. Performance and durability are excellent, but if you want the install to be painless you will pay for that elsewhere. For owners who care most about a filter that seals and lasts, the WIX is hard to beat.
- Thick steel base plate resists warping and gasket leaks over time
- Silicone anti-drainback valve for reliable cold starts
- Strong pleat count for good dirt-holding capacity
Pros: Among the most overbuilt cans you can buy for the HEMI; Silicone valve and metal end caps for durability; Consistent quality control batch to batch
Cons: Plain exterior with no removal aids; Slightly heavier than OE, no functional downside but noticeable
4. Mobil 1 M1-110A Extended Performance Oil Filter: Best for Long Intervals
If you run full synthetic oil and stretch your changes toward the long end of the HEMI service window, the Mobil 1 Extended Performance filter is engineered for exactly that. The synthetic media chases very fine particles and holds a large volume of dirt before it loads up, so it stays effective deep into a long interval. The silicone anti-drainback valve protects against dry starts, which matters more the longer the filter sits between changes.
The catch is fitment diligence. Mobil 1 offers several filter sizes and the correct one for the larger HEMI body must be confirmed against your specific year and build, since the wrong number can be too short and lose media area. Once you have verified the right part, this is a superb long-interval choice, though it is genuinely more filter than a person doing frequent short changes needs.
- Fully synthetic media targets very fine particle filtration
- Rated to support long oil change intervals on full synthetic oil
- Silicone anti-drainback valve for cold-start protection
Pros: Excellent filtration efficiency for finer particles; Designed to go the distance on extended synthetic intervals; Strong dirt-holding capacity for long service life
Cons: Verify the exact part number fits your year, sizing varies by build; Premium media is overkill for short interval changers
5. FRAM Ultra Synthetic XG10575 Oil Filter: Best Filtration Efficiency
The FRAM Ultra Synthetic is the efficiency champion of this group, using a dual-layer synthetic media that captures a high percentage of fine particles while still flowing well. FRAM also adds its SureGrip coating to the outside of the can, a textured non-slip surface that genuinely helps when you are trying to spin a hot, oily filter off the tucked-away HEMI mount. For owners who obsess over keeping the engine internals clean, this filter delivers.
As with the Mobil 1, the warning is fitment. The XG line comes in several lengths and you must confirm the number that matches the tall HEMI filter body rather than grabbing a generic FRAM off the shelf. Some owners also feel the premium media and coating push it into a price tier that only makes sense if you run long synthetic intervals. Match the right part to your truck and it is one of the cleanest-running filters you can fit.
- Dual-layer synthetic blend media targets very high efficiency
- SureGrip textured coating makes the filter easy to grip and remove
- Metal screen backing supports the media against pressure surges
Pros: Very high rated filtration efficiency on fine particles; SureGrip coating actually helps on the oily HEMI install; Long service life suits extended synthetic intervals
Cons: Confirm the XG part number matches the larger HEMI body; Premium price tier relative to a basic filter
6. ACDelco PF2257G Professional Oil Filter: Most Reliable Value
ACDelco Professional filters are a known quantity for anyone who has worked on fleet vehicles, and the PF2257G brings that steady, no-surprises quality to the HEMI. The media offers solid capacity for normal oil change intervals, and the thermosetting adhesive holds the seams together against the heat this engine throws off. It is the kind of filter you install and never think about again until the next service.
It will not win a filtration shootout against the synthetic-media filters higher on this list, and there are no grip or drain features to ease the install. But for an owner who changes oil on a sensible schedule and just wants a reliable, properly built filter at a sensible value, the ACDelco is an easy recommendation. It does the core job well and rarely gives a reason to complain.
- Professional grade cellulose blend media with solid capacity
- Thermosetting adhesive seals seams against high heat
- Consistent OE-style construction and pressure spec
Pros: Dependable, no-drama filter from a trusted OE supplier; Strong sealing under heat for leak-free service; Good value for owners who change oil on a normal schedule
Cons: Filtration is good rather than class-leading; Plain can with no removal features
7. Royal Purple 10-2867 Extended Life Oil Filter: Best Synthetic Pairing
Royal Purple built the Extended Life filter around Micro-Glass synthetic media, the same kind of high-efficiency material used in premium long-drain filters, and it pairs naturally with the synthetic oil most HEMI owners already run. The canister is heavy-duty and the silicone drainback valve keeps the filter primed, so it is genuinely engineered for owners who push their intervals while keeping the engine clean. On a HEMI fed good synthetic oil, this filter rounds out the system nicely.
The drawbacks are a steeper price than mainstream filters and the usual need to confirm the correct part number for the tall HEMI body before you order. It is also arguably more filter than a short-interval changer needs to buy. But for someone running a top-tier synthetic and looking to match it with an equally serious filter, the Royal Purple is a logical and well-built pairing.
- Micro-Glass synthetic media for high efficiency and capacity
- Designed to pair with full synthetic oil on long intervals
- Heavy-duty canister and silicone drainback valve
Pros: Excellent particle capture for finer contaminants; Pairs naturally with premium synthetic oil; Built for genuinely long service intervals
Cons: Pricier than mainstream filters for the same fitment; Confirm sizing for the larger HEMI body before buying
Frequently Asked Questions
What size oil filter does a Ram 1500 5.7 HEMI take?
The 5.7L HEMI in the Ram 1500 uses the larger filter footprint, matched by the Mopar MO-339 and its aftermarket equivalents like the WIX 57060, K&N HP-2009, and ACDelco PF2257G. This is the tall body filter, not the short compact size. Be careful when cross-referencing synthetic filters like FRAM Ultra and Mobil 1, because those brands offer several lengths and the wrong number can be too short, costing you media area. Always confirm the part number lists your exact year and the 5.7L engine before buying.
How much oil does the 5.7 HEMI hold with a filter change?
The 5.7L HEMI in the Ram 1500 holds approximately 7 quarts of oil with a filter change, which is more than most V8s, so plan your oil purchase accordingly. Chrysler specifies a full synthetic in the recommended viscosity for this engine. The large oil capacity is one reason the filter choice matters, because the filter has to keep a sizable volume of oil clean. Always check your owner manual for the exact capacity and viscosity for your specific model year, since specs can shift slightly between generations.
How often should I change the oil filter on my HEMI?
Replace the oil filter every time you change the oil, never reuse it. For the 5.7 HEMI on full synthetic oil under normal driving, many owners change oil and filter in the range the truck recommends, often around every 7,000 to 10,000 miles, though the dash oil life monitor is the better guide. If you tow heavily, drive in dust, or do lots of short cold trips, shorten that interval and lean toward a heavy-duty filter like the K&N or WIX. Severe service is hard on both oil and filter media.
Does the oil filter bypass valve really matter on the HEMI?
Yes, the bypass valve pressure setting is among the most important and least visible parts of a HEMI filter. The valve opens to let oil bypass the media if the filter clogs or if cold, thick oil cannot flow through fast enough, protecting the engine from oil starvation. If the valve is calibrated wrong, you can either starve the engine or let unfiltered oil circulate too often. This is a big reason the OE Mopar filter and reputable brands matter, because they match the HEMI oil system pressure spec, while bargain filters sometimes do not.
Why is the HEMI oil filter so hard to remove, and how do I make it easier?
The HEMI filter sits in a tight spot that gets coated in hot oil, which makes it slippery and awkward to grip by hand. Two filter features help a lot here. A welded nut on the base, like the K&N HP-2009 has, lets you put a wrench or socket right on it. A textured non-slip coating, like FRAM SureGrip, gives your hand or a strap wrench something to bite. Using a good cap-style or strap oil filter wrench and only snugging the new filter hand-tight, not over-torquing it, makes the next change far easier.
Our Verdict
For most Ram 1500 5.7 HEMI owners, the Mopar MO-339 is the top pick because it matches exactly what the engine was designed around, from the bypass valve pressure to the silicone drainback valve, with zero fitment guesswork. If you tow or work your truck hard, our runner up is the K&N HP-2009, whose heavy-duty canister and welded removal nut make it the practical choice for a truck that pulls weight. Whichever you choose, confirm the part number lists your year and the 5.7L engine, change the filter at every oil service, and pair it with a quality full synthetic to keep that V8 running clean for the long haul.
