    The installation would have been easier if the hose that attaches the unit to the engine was 1" longer.

    Works great

    I wish I could return this product and get my money back. I haven't notice any gains in hp or mpg. I will be going back to the stock ome intake, what a waste of money.

    No performance increase & in fact, a noted reduction in gas mileage. Prior to installing the K&N 57 Series FIPK Air Intake, I was averaging 12.8 mpg per on-board computer. Since installing, I am now averaging 12.4 mpg. However, noise level has increased on acceleration, if one want to consider that to be "performance". Save your money for some other product.

    Great addition

    I thought it was a little pricey at first but after installation I realized the value. Installation istructions were step-by-step and easy to follow. Noticed immediate increase in performance and appears to have helped the gas mileage (still checking it). Very satisfied and would purchase again.

    Great , like the looks , and the performance I got !!!

    I was disapointed with the fit, the shroud was gasketed like it was supposed to seal the fresh air from the engine compartment, which it is, but the sheetmetal was inches away from completing the seal.
