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!

I purchased this air filter (33-2031-2) for a 2006 Red Infiniti Coupe. I noticed the change immediately. First I noticed the gas savings, The car sounds completely different. Definitely more horsepower. I love it. I really do. Change your life change your filter it is worth it.

Great product!

Delivery was quick, can't fault the product. If you need a new filter why not get one that will last and preform better.

Excellent product with clear, but unnecessary installation instructions. Car seems to have slightly benefited from the easier breathing.
