K&N 33-2306 Air Filter Product Reviews

Tuesday, April 12, 2016 - Part 33-2306
I purchased this air filter for my 2014 Tacoma. I have a 4 cylinder and wondered how much difference this filter would actually make. I have to say I am very impressed. Not only do I feel a slight increase in power but the engine has a more aggressive throaty sound to it now which I love. I haven't have the truck long enough to compare MPG's but I am quite happy with the performance of it. Will definitely recommend.

Appears to add some performance, especially when you have 20 wheels with a Toyota 4 cyln 2.7 engine. Makes going uphill with less effort. Has extra boost when accelerating over 60 MP to pass. Consider a worthwhile option for the price.

I got this for my Tacoma 4 cylinder pick-up truck. While I would not describe the acceleration on the truck as zippy the K&N filter does add a noticeable gain in power, particularly when going up long inclines.

I've been using K&N filters on my motorcycles, cars, and trucks for years. They always help the engine breathe more efficiently and give me slightly better gas mileage. They're easy to clean when needed and last the life of whatever vehicle or bike I put them on. Don't mess around - these filters are superior to anything else out there.
