Review on 🚀 K&N Engine Air Filter: High Performance, Washable Replacement Filter for 2004-2019 Nissan/Infiniti (Frontier/Titan/Pathfinder/Xterra/Armada/Equator/NV1500/NV2500/NV3500/QX56) - 33-2286 by Brad Fleming

When I buy a car, the first thing I do is replace the stock air filter with a K&N filter. The power gain is marginal, but I noticed a healthy intake growl under hard acceleration. The mpg increase is nominal (1/2-1 mpg maybe on the 2015 Frontier 4.0 V6), but I really appreciate not having to change the air filter again. Is always. Traditional air filters cost less, but need to be replaced from time to time. Installing a K&N filter is a long-term cost saving that pays off many times over. Regular cleaning is quick and easy. You will find many different opinions on how well they work but having used them on several vehicles all I can say is that they work for me.
