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 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.

Although it may seem expensive in the beginning but you'll be saving a lot more money in the future! Its a great investment. Always use best of best!
