"I wish I had known about this product sooner. I have a 2004 TSX and I was averaging 26.7 MPG, since replacing with K & N I am averaging 29.89 MPG. Hard to believe but that is what the numbers look like. I am glad I purchase this product. I have also ordered one for my wife's car. Three of my friends also ordered filters for their cars. Great Product. I would highly recommend it. Don't expect a big jump on performance. My TSX is only 4 cyl. and already packed with 200 HP so I don't expect to get anymore out of it. Definitely a gas saver and the car does run a little smoother. Definitely recommend it." —Mehedi H from New Brunswick, NJ bought a K&N Air Filters for a 2004 Acura TSX.
