Great sturdy material. Shiny chrome and nice deep red color. Functions as it should, improved HP by about 5. Definitely a starter mod for bigger builds. Throttle response is definitely faster compared to the stock intake on my MK5 Rabbit

Der Luftfilter kam in einem super Zustand an, auch wenn ich ihn gebraucht über einen Händler gekauft habe. Habe nur die Hälfte bezahlt und trotzdem einen neuen Luftfilter bekommen. Passt auch perfekt auf das Rohr was ich dafür habe (75mm Außendurchmesser)

I wasn't sure about the "universal fit" feature, mostly because Amazon had a warning that this item was frequently returned. It fits my S-10 cold air intake tube perfectly, and it looks great.

What I expected from them. High quality filter at a respectable price. Was a little big for my PRL High Volume Intake so I had to shave a little off the intake but now it works perfectly. Would buy again but don't need to because it's rewashable

トップからも吸えて吸気効率も良さそうですし、値段もお買い得で助かりました。吸気音も高級感が出たものとなったし取り付けもバッチリ出来たので言う事ありません。

Received an original K&N filter fully packaged with stickers and instructions. Had much louder induction noise because of it. Very happy.

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👍.
