K&N 33-2145-1 Air Filter Product Reviews

Wednesday, March 14, 2018 - Part 33-2145-1
I wasn’t sure if any result would come from installing this filter,but from experience and what I’ve seen online I thought I’d give it a try. The installation was very straightforward and simple. I installed it in my car with a full tank of gas and was going to do some freeway traveling. By the time I was done and my tank going in empty,the mpg was something I’ve never experienced. I had to do double takes just to be sure. 1998 Toyota Camry got over 400 miles on a tankful. WHAT? Yup,I couldn’t beleive it. Now remember this was mostly highway mpg,but dam,that’s impressive Look forward to installing one on my Lexus GS350

Swapped out the old OEM filter for this one and it’s a noticeable difference on the first drive. Running on a Toyota Solara 2000 Less RPM on highway cruising and my engine temperature stays cool +mpg. Highly recommend.

This is the 4th vehicle that I have purchased a K&N filter for. In each case I have seen an increase in horsepower and the opportunity to get better gas mileage.

For a 1997 Toyota Camry V6...perfect fit, good quality. I did not notice a big power increase, bit it was always a zippy car anyways. Thanks
