K&N filter's are a very good product for increased power and fuel ecinomy. I recently ordered one for my S-10 pickup. Have not yet installed it, it was a present for me. I have used K&N before in my S-10 Blazer and my 4-wheeler for increased power and fuel economy in both and all you have to do is clean it every so often, never throw it away just clean it and oil it and put it back in. GOOD PRODUCT. The price costs a little, but you only have to buy once then keep clean and oil every so often and your good.

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.
