Pricey Filters !!!

My Jap Vette uses two air filters and even with AA's discount over a hundred bucks isn't cheap, but K&N guarantees filters for a million miles. Just like washing your car makes it run better, these filters seem to add power. That's probably psychological, but the engine does sound louder when throttling hard, and mileage seems better, well satisfied. Your Welcome!

Great product

Great upgrade to the stock air filters. Improved throttle response and gas mileage seems to be improved. K&N is the best in the business.

I added twin filters to my wife's 370Z and she even noticed a small performance increase. Good value for the money and should help gas mileage as well.

Installed a pair of K&N airfilters on my 2015 370Z Nismo. Easy to install and fit the factory airboxes like a champ.

Easy to install and not much more expensive as originals but will last a long time.
