We tested 4 of the best performance air filters to see which one was the best. From their ability to filter out contaminants, their capacity and horsepower increase. We are diving deep to see what makes these filters tick. So if you want to find out which one takes the crown, then stick around. #engineairfilter #airfilter #test #K&N #AEM #SPECTRE

You should have included a "standard" paper air filter for comparison in all of these tests, especially for the filtration test. The whole point should have been whether these so-called "high flow" filters are meaningfully better than the typical fram/purolator OEM style filter.

Project farm showed K&N let a lot of contamination through the filter! There’s no need for a performance filter!

I had a 2020 Ford Ranger with the 2.3 liter. I got a performance tuning kit directly from Ford. The kit was a reprogramming of the computer and a K&N air filter. It's interesting that the manufacturer had no problem with the K&N. This was an easy way to get a great power boost and keep the warranty.

I just stick with WIX air filter. I hope I make a good choice. I not sure how good it works though.

Great video, as an AEM user I feel this is the clear winner because of filtration which is more important than a few hp extra. Was happy to see AEM excel in filtration. Cheers

I was just looking at some of these air filters last night... good timing. Thanks for the heads up on rockauto also. Almost paid triple for one Spectre Performance.

Love this video! The visuals are incredible, they've got me geeking out over air filters! Never thought I'd be inspired to change my air filter, but now I'm eager to upgrade for better airflow.

Great video. Keep in mind of the "Magnuson-Moss Act". Part of the reason K&N's warranty is the way it is because the manufacturer has to prove that a 3rd part/aftermarket part is what caused the problem. Way too much speculation over the past several decades over the K&N filtration, performance and longevity of both the filter and engine it operates with. I have never seen an engine fail from an aftermarket filter let alone know anyone who has proven it caused a problem without user error/neglect. If these aftermarket filters were so bad, engines would be blowing up left and right and these companies would go out of business. You should watch videos of folks around the world with performance filters in their off-road vehicles running these type of filters with no issues. Not to mention it doesn't help when you hear people parrot the same old exact negative comments of things like, "the oil made me get a CELL even though I technically over oiled it", "it killed my engine but I never cleaned it for over 5 years driving in dusty country backroads", etc. etc. It's not a black and white answer as it's a combinations of factors but one thing for certain in my experience is I've never seen an aftermarket filter cause engine issues without user error.

Most people trade in their vehicles ever few years like they do with cellphones to the point they'll never really truly know if their filter did cause engine issues.

I had a K&N on my old forest service truck because the stock filter is almost $40, so it seemed like it was the obvious choice. I pulled it out after less than 500 miles because there was light dust on the "clean side" of the air box. Also if you over oil these filters the mist will compromise your mass airflow sensor. K&N good on the drag strip to keep moths out, not good off-road. I was told that I need a dry pre-filter sock by a local off-road shop, how do you do that on a stock air box? Pass.

I started using K&N filters way back in 1972 on my Honda 750. Used them all the years since on every vehicle I owned until 2015. That’s the year I bought a Polaris RZR side by side. It was a 2010 model. The very first thing I did was add a K&N filter. I had been to two different Polaris dealers who both mentioned off hand to never use a K&N filter. I thought they were full of bs and even recommend that my brother-in-law put one in his RZR. After a couple of rides his RZR stopped idling. We took it to the dealer and they found that the intake tract was all dusted up and the throttle body had to be replaced. I checked my RZR and found dust in the intake. We both switched to oiled foam filters and never had any more dusting problems. My brother-in-law also had been using K$N filters in all his vehicles for years. We have never used them in anything since. Hard to believe after all those years I found out the filters were sub par.

Missed on not including the values from the last video with traditional filters. Particle counts on those were about ~12000 vs. the ~18000 for these performance filters.

[ChristianMelgar-dy]

Awesome love your videos .. I have more brand ideas for performance filters, PRL, AFe, BMC, Green Filter, KAK, DNA Motoring, HKS Super And for the regular filter you can do dealership filter like Honda, Toyota, etc.

[SilverMustangGT]

ANOTHER great video! Love the content. Side note, it would be awesome to see you guys test some racing oil filters! Throw in a Fram Racing & Ford Racing! Goes great with this performance filter video! 😊

[Llama]

Would love to see you compare stock air filter contamination levels vs these. K&N and similar have always let more dirt in from what I've seen, especially when not oiled etc.

[khoahoangnguyen]

Love the content and the metrics your channel provides.

I would love to see how other performance filters like Injen dry filter, AFE Pro 5R oiled, and AFE Dry Flow would perform; also ITG and HKS foam filters. Does a prefilter help or hurt in any significant way (restrictiveness and filtration)?

Thanks again for your videos!

I live in Michigan. It's cold 4 months of the year. I read articles over 30 years ago explaining how the oil in K&N filters gets more viscous as the temperature drops, yes this controversy has been going on for a long time, and filtration drops due to the oil not being able to provide adequate filtration in cold temperatures. So the advice was to use an oiled filter in the summer and a stock filter during cold weather. I have always thought the reason for the filter is to keep abrasive contaminants out of the engine. The only way to achieve more filtration and more air flow at the same time is to use a larger filter. Plus the very slight increase in horsepower with and oiled filter is only available during wide open throttle. So, we would put a taller filter element in the round filter housing that sat on top of the carburetor, the top of the filter housing would sit up an inch or so and provide more air flow. As long as the hood would close. Now I run a good brand stock type filter. Because dirt inside the engine is well, BAD.

This is great news you can use, thanks Brand Ranks!!

You guys are becoming one my favorite car content channel, keep up with the good work 🔥🔥

Been using K&N for 25 years now. No issues that I could trace back to the air filter letting too much dust through.
I've always used the original K&N filter soap and oil and usually I apply some extra oil to a brand new K&N Perf. filter.
(50-50 mix of oil and IPA in a little spray bottle to apply it evenly)
If you do all your vehicle's maintenance yourself - and do it regularly, then they're definitely worth the money. If you factor in the cost of cleaning material and oil I'd say the actual cost savings are negligeable, though.
In the end it's an hour of work per year for a couple more HP.
