K&N 33-2144 Air Filter Product Reviews

Wednesday, September 12, 2018 - Part 33-2144
This is my third filter, I do not clean them. I tried another brand non oiled and my mileage dropped 14. The cost in two months was going to be more than a new K&N filter in gasoline, so I switched back. I have 2003 Lexus GX470 with 200,000+ miles and it has a 3.7L V8 that gets so so mileage. So any improvement is a blessing. Changing from my last K&N filer with 45,000 mileages on it to the new one gave me 4 better in town mileage. They are worth the money. In the years I have used them there has been no problem of any kind. We have done several 18 drives up and down mountains and freeways with ease. I hardily recommend them.
