I ordered my Fram AirHog online from Advanced Auto Parts for about $40. Part Number PPA7597
  • 1. Remove your air filter box to a work bench.
  • 2. Remove the filter plate and with a utility knife cut out the white paper factory filter.

  • 3. Replace it with the AirHog. I suggest using some adhesive like Perma seal gasket sealant to hold it in place.
    You could stop here and bolt it back up in the car and see some improvement.
  • 4. I purchased a 3" hole saw at Lowes to drill my hole in the airbox. You can use the picture and count the ribs to identify the location.
    Hang onto that box when you drill because when you first start it will want to jump out of your hands!!
  • 5. Inside the box you will see a waffled area of a lot of small squares around a factory 3" hole. With a 3/8" or 1/2" drill 35 holes in the square waffles.
    This is to balance additional air for the 3" new hole you cut.
    The picture shows a lot more holes but you only need 35 to equal the area of the newly cut 3" hole. Clean up is a mess
  • 6. Cut a hole in the flexible skirt behind where the airbox was. This is an opening to the same air chamber that the stock 3" hole draws air.
    Aligning the newly cut hole in the airbox to where you cut your hole in the flexible material is tricky.
    I suggest cutting it oversize to cover your bases.
  • 7. At your front bumper, driver's side is a plastic panel that you can easily push out with the handle of a screw driver.
    This lets fresh air into that air chamber instead of under the car.

  • 8. put your airbox back in the car and clean up. Usually takes about 90 minutes and two Budweisers.

    Good luck! Let me know how it goes. If you find details missing let me know so I can update the instructions
