Going on third vehicle with same filter. Originally a Isuzu Rodeo and after 175k miles engine blew a head gasket, replaced it with a Isuzu pickup from my with and put another 120k on it. Tranny started slipping and it wasn't 4x4 so got a Blazer. Have almost 250k on Blazer. I might make that million miles. Keep a cleaning kit in truck when I have oil changed so they can clean filter. All is well and gonnna stick with them.

Added this K&N Filter to my 2000 Safari SLE (with 80K miles) and within a tank full of fuel, picked up about 1.3 MPG and shaved a full second off my 0-60. Was an easy install, instant sound and power boost. LOVE IT. Thanks K&N.

I have been using K&N oil and air filters for years. I have added dual exhaust and a performance chip to my '96 Astro. I recently changed the standard K&N filter to a big cone style. My chip module is still adjusting to the extra air flow. My little 4.3L V6 is amazingly fast. I have had a number of fast cars back in the day of big cubes but not a lot of HP. Try K&N filters and you will feel the difference. I only change my oil twice a year, I don't put a lot of miles on it and I use good high mileage oil. When the oil is changed it is quite clean. K&N is the best of the best.
