 Great product and super fast shipping.Thanks to the suggestion sheet everything went smoothly with the installation, and I had it installed in twenty minutes.The only other thing that I did was to remove some dirt that was in the bottom of the air filter tray.I can see by the thickness of the stock filter compared to the K&N why it is so much better for power/performance at least the poor engine can breathe a lot better now.Thanks, I will be back for more of your products.
