    • Fabbed up a custom CAI.

Custom CAI couldn't have turned out better, I was going for the "sleeper" style of intake but didn't like the idea of cutting a hole in the hood for a ram cowl induction. This filter as some of you know, it being a K&N filter needs to be oiled and washed to keep contaminants out. The filter pricetag was pretty cheap considering the quality you are getting. The filter looks well made, no factory defects I can see of. If the filter is ducted like I did, you get the added bonus of the intake rush noise, and colder incoming air. No more 'hot air intake' with the filter being setup this way also, just be sure to not choke the engine of air, or you're going to be running the engine with a rich A/F, Size ducting accordingly. The only part of this project that sucked was that I needed to cut a hole into the radiator core support, for the ducting/filter to come through. ... show more

    • Amazing Sound and it’s a K&N
Review Image by John W Billington IV John W Billington IV
Awesome universal cone air filter. My install was easy just added a tube and cut a hole for the MAF sensor. Such an amazing sound when driving around, I feel like it makes my car faster at acceleration and definitely the sound is loud at increasing RPMs. Did set my check engine light On but with a small fix it stays off. I would highly recommend buying and installing on your car. 👍 👍 Installed on a 2016 Mitsubishi Outlander Sport 2.4 liter awd ... show more

    • The best or nothing
I drive a 2013 Ford Escape se 1.6L ecoboost Alright I start off by saying I have been wanting a K&N filter for a long time, but I have slacked on getting one. I finally had no other choice but to get this, due to the paper filter in my car was so clogged my car performance hit rock bottom it felt sooo sluggish even going 80mph and my gas mileage went down hard. (My Fault for waiting to long 😓😬). My engine light was coming on because my (turbo) the psi was higher than it should be due to the clogged filter. I don't think there's no other brand like K&N and the name itself makes you think the best. It arrived very fast, I'm a 28 year old guy with light experience in cars. I didn't have any tools so I took it to AutoZone main hub, I never changed a filter before so I didn't know what I was doing yeah yeah laugh. I'm one of those people show me the first time and I'm good to go. A worker came with some tools and helped me take off the old filter. MAN oh MAN the filter was packed with stuff and dirty dirty. So I took out the K&N filter and just seeing the way it looked gave me chills. The process was very easy but you do need a couple of tools for screws and a flat head screwdriver to un-loosing the clamp on the K&N filter to fit properly. Alright so Its on, I take off, BRUH!!!!! The car took off super quick, pushed me in my seat no lie. I can hear the filter sucking in a gulp of air saying I can breathe and my turbo was hissing so loud in a good way💯👍. Just hearing the air filter do it's thing is so cool, I seem to have more power and I definitely can take off even faster. My gas mileage has improved a lot Thank God!!! Please get this, don't wait like I did, upgrade to the K&N because those paper filters don't have fence locks like K&N does to block most of the bad dirts and grimes, this is the best filter hands down. Thank You K&N for these filters!!! I will stock up on these and also got the cleaning and re oil spray on the way👍. ... show more
