2. aFe 73-10102 Pro Guard 7 Air Filter

aFe Power’s pre-oiled filter is not only going to last you for a long time, but you can also wash it every so often to ensure you can use it again. With the company’s proprietary design, dirt and dust will have a hard time clogging your engine and reducing its efficiency. Made of 100% pliable polyurethane, it’s tough and won’t fail you easily.

The technology in this air filter is patented by aFe Power, called “Pro-GUARD 7 oiled Five-Layer Progressively finer mesh”. The mesh has been designed to filter dust and dirt to the maximum, not allowing the finest particles through. The material is also washable and reusable, which means that you can save a lot of money instead of buying more disposable air filters.

The seven layers are made of both synthetic and cotton gauze media, and they provide 99.7% filtration efficiency all the time. 

This reusable air filter allows you to take your pickup truck through the most extreme of environments and you can later check your engine and see that little dust, if any, made it past the filter. You can simply wash it and put it back after drying it. It will last you through multiple cleaning cycles.

The rounded open pleats in this air filter allow for more dirt to be contained and prevented from contaminating the engine. This large surface area also allows for increased airflow into the engine, crucial for function and performance. Instead of being too cluttered, this means that your engine will be allowed ample airflow and still be protected from dust.

The polyurethane used in the air filter’s construction is pliable as to prevent breakage and improve longevity. It will withstand vigorous cleaning many times and eliminates the need for foam gaskets and sealing grease, and the latter can become very messy to clean when dirt clogs up. As polyurethane is chemically stable, normal chemicals will not erode it and it will power through the common elements without issue.

Buying this air filter from AFe Power also gives you a life-time warranty! A great reason why it is on the list of best air filters for the 6.7 Cummins.

3. Spearhead Max Thrust Performance Engine Air Filter For All Mileage Vehicles – Increases Power & Improves Acceleration (MT-261)

Made to fit the 6.7 Cummins engine, this Spearhead air filter is a great pick if you have a lower budget but still want a quality filter that can both protect your engine from debris and improve your overall vehicle performance. This filter is a great aftermarket accessory that can replace your stock filter. Who doesn’t like saving some money?

With up to two times the dirt protection when compared to stock and factory filters, Spearhead made it to replace these lower-standard products. The Hex-D pleat design allows for extra space to hold the dirt in place. The multiple layers keep the dirt from entering while still allowing air to flow into the engine space, thus ensuring engine performance is at great levels.

Because of the improved airflow, you can find an increase in mileage with your pickup truck, and Spearhead claims that it’s possible to increase it to 15,000 miles. With common air filters, air can’t reach the engine, and this results in performance drops, and you lose money for fuel. With a filter that always allows air into the engine, not only you mitigate this, but you can even increase your performance.

Spearhead recommends replacing this filter every 10,000 or 12,000 miles, depending on intensity and other factors. This helps you save money rather than spending it on mediocre filters that have to be changed much more frequently. This distance would translate to around a year of driving.

By installing this air filter, you not only let the filter pay for itself, but you reduce fuel costs in the long run, as well. What’s not to love? With a low price, you can even use this as a backup or interim air filter until you decide to get another more expensive filter.

Specifications

Weight: 1.85 pounds

Size: 11.6 x 10 x 4.6 inches

Parts Included: 1+

Pros:

  • Strong dirt protection

4. Flowmaster 615024 03-20 Ram 2500 6.7L, Performance Air Filter

From Flowmaster’s Delta Series comes this air filter panel for your 6.7 Cummins engine. It’s another affordable way to save some money on your air filter expenses, though it’s not as cheap as the Spearhead filters above. Regardless, it’s above average in terms of quality and you can rely on it when you install it in your truck and go out driving.

The cotton gauze used to protect your engine from the dust and debris in the outdoors has been pre-oiled to improve filtration, and it’s not a single-layered design but multi-layered. It’s a cut above many paper air filters that come with the vehicle straight from the factory. Not only does it last longer than factory air filters, but you can also refresh it with a Delta Force Refresh Kit so it can continue working in your vehicle.

Compared to the factory air filters you get from the manufacturer, these Flowmaster replacements will also give you a performance boost other than better filtration and protection. This is due to the better mesh gauze allowing more air to flow into the engine. As all drivers know, the more air the engine can get, the better the engine is at performing at maximum efficiency.

Tough gauze isn’t the only strong feature of this air filter, though. The outer frame and seal is made of a durable polyurethane which also fits directly into the factory slots due to the precise manufacturing. It would take a lot of abuse to crack the air filter frame, meaning you can relax while driving in tough conditions.

Due to the way these air filters are made, installing them as replacements of your original hardware is quick and easy. It’s not expected to have to modify your pickup truck in any way when you install one. Bear in mind that you have to ensure your truck is a compatible model before doing so.

With regular maintenance to your vehicle in conjunction with this air filter, you can give your vehicle the boost it deserves.

Premium Guard guarantees that these air filters will fit your 6.7 Cummins engine and protect them from dust and debris, all while exceeding the performance of factory air filters. These air filters address the main flaws of original air filters and solves them as much as possible. This allows both the air filter and your vehicle to perform at their absolute bests all the time.

The three problems that need to be addressed are efficiency, restricted airflow, and how much dust the filter can hold. Not only will Premium Guard filters outperform standard filters, but they will do so longer. Now you don’t have to replace your filters as often as before!

The amount of dirt and other contaminants that an air filter can trap is its efficiency, and Premium Guard’s air filters have a 99% rating. This will last as long as the filter is functional, perhaps only dropping slightly over time. However, this is a much better performance than stock air filters that come with your vehicle. 

Most stock air filters have a problem with restricting the airflow to the engine, and this will cause the engine to require more fuel to perform at the standard efficiency. Premium Guard designed its air filters to maximize the flow of fresh air into your pickup truck’s engine, thereby increasing overall vehicle performance and power. You also save a lot of money on fuel in the long run and you’ll find yourself driving further than before when you stop to refuel.

Original designs in the factory filters are often not as good as aftermarket products, and Premium Guard’s air filters will not only capture and contain more dust, but it can do so for longer. Now your engine won’t be so dirty and contaminated. You also don’t have to replace your air filter that many times over your vehicle’s lifetime anymore!
