K&N 66-1401 X-Stream Top Filter Product Reviews

Sunday, October 16, 2016 - Part 66-1401
This product has improved all breathing aspects of my Ford big block 460. No change in carburation was needed. The overall satisfaction of installing this low-cost, high gain element, is indeed, very satisfying.

Product works great, added a 14x3 air cleaner element, truck runs awesome now. More power, better mileage. I recommend K&N products to everyone.
