K&N 33-2452 Air Filter Product Reviews

Thursday, March 15, 2018 - Part 33-2452
I installed the 33-2452 drop-in air filter into my 2016 Lexus IS 200t F Sport about a week ago. I haven't really noticed any real change in the sound of my engine (or turbo) but it does seem like my car has a bit more power now. Particularly once I get up to about 45+ MPH... thats when I can really start feeling the difference (I guess because thats when a more significant amount of fresh air starts getting pushed under the hood of my car and into the filter).Its not a crazy boost in power but definitely noticeable. It also looks like I might be getting about 1 more MPG than I used to get. I realize this is still only an air filter so I wasn't expecting an astronomical change. So I do feel like I got what I was expecting...a slight bump in performance and fuel efficiency from a quality air filter that was very easy to install. I am very happy with this product. (Note: this air filter did come pre-oiled.)

Like previously mentioned in one of the comments, it is hard to explain how great of a product this is. Instantly felt more HP in my car and you can hear the car breathing in air better. I highly recommend.

I have used K&N filters for many years. They are great and seem to give a little more horsepower and sound to your car.
