K&N Air Filter Sept 1, 2019 18:18:18 GMT -6 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by nuflat1 on Sept 1, 2019 18:18:18 GMT -6 Just added an K&N Air Filter to my Blazer RS. Hoping to see a little increase in air flow and gas mileage. I have put one in every vehicle I have owned for the last 25 years and they haven't failed me yet.www.knfilters.com/air-filters/chevrolet/blazer/3.6l/2019
