1. Best OEM Replacement: Fleetguard Oil Filter for Dodge Ram Cummins – the Best Oil Filter for 6.7 Cummins

No products found.

A solid straight-fit OEM/factory replacement choice is the Fleetguard Oil Filter for Dodge Ram trucks. It’s made for highway use only. It’s also available in a pack of 2, 3, and 12, depending on what your needs are, but for this review, we’re referring to the pack of 1.

100 percent 30-micron efficiency

Its Stratapore media should improve filtration. It’s got a 100 percent 30-micron efficiency, is 6.945 inches tall and has a thread size of 1-16 UN-2B. The Fleetguard LF16035 is compatible with a variety of Dodge Ram/Ram trucks. It’s best to check with the seller about finer compatibility details. According to the official data, the oil filter, which is said to be compatible with all Cummins (5.9 and 6.7) diesel-engined trucks, it’s a part of the maintenance kits by the company — and that includes compatibility for trucks with the 6.7 Cummins engine and model years 2007 – 2018.

Why do we like it?

The Fleetguard Oil Filter is closely related to the stock filter and works well as a replacement. Message the seller about compatibility and warranty before making the purchase. This filter has a great reputation among Dodge/Ram owners and enthusiasts. That’s not only because it’s a well-known brand (responsible for making good quality replacement parts for eons) but also because the filter is very good. Most users appreciate the competitive price and the trouble-free ownership experience.

2. Stock Choice: Mopar/Genuine Chrysler Oil Filter

No products found.

This is a direct-fit, stock-replacement part that can be installed to replace the same oil filter (probably) that your truck came with. While that means there will be no difference in quality, it’s the safest bet. Using this means you’re sticking close to the manufacturer-recommended filter spec — one that Ram thinks is best for the 6.7 Cummins engined truck.

Compatible with a variety of trucks

The product here fits 2004 – 2012 Dodge/Ram pickups. It’s made for a variety of trucks (Ram 2500, 3500 models, including the ones with the 5.9-liter engine, but we’re focussing on the 6.7 Cummins only now). All models of the 6.7 Cummins Dodge Ram 2500 and Ram 3500 (regular and quad cabs, and AT) are compatible. We’d still suggest you drop the seller a message about finer compatibility to be sure if it fits your truck.

Why do we like it?

As Dodge/Ram upgrades its trucks, the filter specifications also vary accordingly. Keep that in mind, because a lot of newer models require a finer filter. So while the older one might just fit, it may not be ideal to use it. That’s why we recommend dropping the seller a message. And since the Amazon listing doesn’t have information about the warranty, it’d be a good idea to ask about that as well. Users appreciate that it works well, and is available at a price lower than other stores. It’s easy to install and is less likely to get damaged because of its construction.

3. Easy removal: K&N Performance Wrench-Off Oil Filter

No products found.

With the Wrench-Off Oil Filter, K&N Performance promises high flow rates, which is important, and a consistent flow of oil to the engine. It’s got a heavy canister shell, has been lab-tested, and will work with a variety of engine oils. It’s made for the 6.7 Cummins Dodge/Ram trucks and works well as a stock/factory replacement.

Said to trap 99 percent of contaminants

The filter media is said to trap 99 percent of contaminants, ensuring that only the clean oil reaches the engine. In addition to that, with its exposed nut, removing the filter is easy. Furthering the oil filter’s appeal is an anti-drain-back valve (available on select models) that prevents oil from reaching the crankcase during the engine shutdown. It also eliminates dry starts.

It’s made to last the manufacturer-specified service intervals and is backed by a 1-year limited warranty. It’s got a filter size of 1 inch/16UN 2B, an overall height of 7.188 inches and a weight of 1.5 pounds.

Why do we like it?

It’s always a good idea to check with the seller about finer warranty and compatibility details. In this case, the oil filter is compatible with almost all 6.7 Cummins Dodge/Ram trucks (2500, 3500, 4000, 4500, and 5500 models). For the Ram 2500 and Ram 3500, the oil filter can be used in 2007 – 2019 trucks. Please check with the seller about other models. Users appreciate the ease of removal, overall quality, and the low price of the K&N filter for 6.7 Cummins.

4. Inexpensive replacement: WIX Filters Spin-On Lube Filter

No products found.

Oil filters don’t cost much but if you’re looking at an inexpensive alternative to stock ones, the WIX XP Oil Filters product might be the one for you. It’s tested to be 99 percent efficient at 35 microns, is claimed to last the OEM oil and filter change intervals, and resists premature plugging due to breakdown of oil.

Solid price advantage

It’s a Spin-On filter, has a 1-16 thread size, a maximum flow rate of 12-15 GPM, and an overall height of 6.945 inches. The filter is available at almost half the price of other popular models, but as the reviews suggest, it’s more than half as good as those. 

It’s compatible with the 6.7 Cummins engined Dodge/Ram trucks in various forms. An overall compatibility charge suggests the oil filter can be installed in a wide variety of 6.7 Cummins trucks — Ram 2500 (2007 – 2020) and 3500 (2010 – 2020), and 2012 versions of Ram 2500 Crew Cab and Ram 4000 Diesel 4×2 are on the list.

Why do we like it?

You’d need to drop a message to the seller to confirm the filter’s warranty. But apart from that, it looks like a solid product. Users appreciate the good performance despite its low price. There are a few types of filters, so check the package you receive to see if you’ve got the right one. This is the XP model. Check with the seller about finer compatibility details as well — while the Ram 2500 and 3500 made with the aforementioned model years are compatible, the compatibility might differ for other models and variants.

5. Great for a daily driver: Mobil 1 Extended Performance Oil Filter

No products found.

Mobil 1 is a trustworthy name when it comes to engine oil, and with the Mobil 1 Extended Performance Filter, it looks like the same can be said about oil filters as well. The filter can offer guaranteed protection for up to 1 year or 20,000 miles (whichever comes first) when used with Mobil 1 Annual Protection oil. Having said that, it can be used with any kind of recommended (for your truck) oil. It’s also backed by a 1-year warranty, and comes with a promise of cleaner oil for your truck’s engine, which will be reflected in its performance and long life.

Filter offers 99 percent efficiency

The filter has a synthetic-blend medium that offers up to 99 percent efficiency and keeps the oil clean from a variety of contaminants including dirt. Mobil 1 claims that the filter is stronger, has a heavy-duty canister that can withstand about 9 times as much pressure in comparison to other economy filters, and comes equipped with nitrile gaskets to eliminate leaks.

Why do we like it?

With a promise to last twice as long (20,000 miles) when compared to regular filters, the Mobil 1 product seems to make a lot of sense. It’s said to be compatible with Dodge/Ram pickup trucks with the Cummins diesel engine made from 1989 to 2019. Considering the 6.7 Cummins was introduced from the 2007.5 model year, the compatibility can be noted as 2007.5 – 2019. Drop the seller a message to check if your particular truck is on the list and about the warranty as well.

6. Inexpensive stock replacement: iFJF Oil Filter

No products found.

If you’re after a replacement oil filter for your 6.7 Cummins engined Dodge/Ram truck, you can give iFJF a try. It’s a standard replacement oil filter, which is said to meet the OEM requirements and comes with a factory-style fit. With the iFJF, you can be assured that installing it won’t be a hassle.

High flow and low restriction

The iFJF filter is said to be made from high-quality materials, so it offers high flow and low restriction. It’s got a thread size of 1-16 UN-2B, a 95 percent 30-micron efficiency, and an overall height of 6.957 inches. That’s quite close to the factory specifications as well. It’s compatible with several 6.7 Cummins models. According to iFJF, you can fit this oil filter to the Dodge Ram 2500, 3500, 4500, and 5500 in the model years 2007.5 – 2018.

Why do we like it?

We suggest you drop the seller a message about finer compatibility and warranty — no information on the latter is available in the listing. Users appreciate that the filter costs less than other popular choices and the stock replacement ones. But the difference is fairly minimal.

What is the best oil filter for 6.7 Cummins?

If you’re looking at replacing the stock filter, and if you follow this guide, there’s no chance of going wrong with your choice. But one thing you should keep in mind, apart from the right compatibility and warranty, is that the oil filter brand meets the exact requirements/specifications as mentioned by the truck manufacturer.

Among the choices here, both the Mopar and Fleetguard filters make for great stock replacements because they’re essentially what the factory offers as well. Would we call them the safest choices? Yep! The iFJF is another contender, and it’s only slightly cheaper than those. But if you’re looking at a more affordable alternative, the WIX XP deserves a second look. Other filters offer something over the stock ones. For instance, the K&N one has a very easy-to-remove aspect to it, whereas the Mobil 1 is backed by a warranty that covers twice the mileage (20,000). So if you drive your truck a lot, it’s worth considering.
