Going into this product, I wasn't expecting a lot. But WOW! What a change. Who knew an air filter could provide such a change? I just put it into my 3.5L V6 2005 Nissan Altima, and I've noticed an increase in acceleration already. I have nothing on MPG yet, because I have just installed it. The engine has also developed this new sporty whine to it at around 4K+ RPMs. Loving this new air filter!

Had K&N air filters in previously owned cars. Lived up to my expectations.
