K&N 33-2252 Air Filter Product Reviews

Monday, February 26, 2018 - Part 33-2252
These air filters are EXCEPTIONAL Here's the thing... if you are on the fence, trying to decide whether or not to buy one of these, BUY IT. Think about the peace of mind knowing you will NEVER have to buy another filter again I mean you'll have to clean it once in a great while, but that's it Now, let me tell you about MY experience...I have a 2003 Toyota Corolla with almost 100,000 miles. The engine is a small one (1.8L) and it's an automatic so it normally would be a little slow on take-off. Driving around normally, I was getting about 25 miles per gallon. The air filter I had was a decent one, or so I thought... it was cloth, not paper (NEVER buy paper filters). Then I installed one of these filters. What a difference The car is quicker, and the gas mileage has increased I'm averaging 28 now, which is where this car should be. I felt it necessary to give a proper review of this product even though I know this is a long review. Even if you just consider the money savings, figure this: $10 average online for a cheap filter, change it every 20,000 miles... if you have the car for 100,000 miles, that's 5 changes... or $50 let's say. That's the price of this filter on average. The same. Just get it. I promise you won't regret it. You'll be thankful you read this Oh and P.S.: All auto-part stores will install it for you for free, assuming you don't know how Thanks for reading -b

This was the first thing I bought for my car in 2007 when it was brand new. At 235,000 miles with no smoke or engine problems I'd say it fulfilled its promise to protect the motor as well as the factory filter.

Really good filter. Easy to install and with lifetime warranty. Gives a deeper sound to the car especially at the higher revs. You won't be disappointed.

Excellent! My engine can really breathe now. Sounds better (deeper, throatier engine rev sound). Used on 2004 Toyota Matrix XRS and the responsiveness of the throttle and the torque and horsepower are all noticably increased. K&N filters work better than I thought they would, I will be getting one for every car I own. Highly recommended.
