Great air filter, I had one on my truck & wanted to replace the stock air filter on my wife’s car. I wish I knew that the “STOP” sticker was included with the filter. I wouldn’t have ordered the sticker separately.

I've used these filters for 30 years. Love the extra and quicker engine response they provide my vehicles. Even my old Prius drove better.

My Acura RX has more pick up but the gas mileage has decreased.
