  14. Unplug the hold down in the large wire harness where the MAF wire ties into it and pull toward the hole. Feed your MAF wires into the hole in the apron. You only need a few inches in there. Put some tape around the hole in the apron. This will help prevent scratching the pipe during install. Bolt Apron Plate up using the stock air box bolt.

  16. Install silicone coupler and clamps on to the JLT tube, then insert round end into the hole in the apron plate and rotate it down and on to the throttle body. Tighten the clamp at the throttle body and leave the clamp on the tube loose for final adjustment.

  18. To gain access in the fender well you must remove the Philips screw in the bumper cover edge and pull plastic fender liner back. There is also 2 push pins holding the shield into the frame rail, remove these too.
  19. Raise the REDUCER/MAF/FILTER assembly up onto the JLT tube. Point MAF top toward the rear of the car and the plug will point toward the driver’s fender. By TWISTING the tube at the throttle body you can gain more room right or left. Plug in the MAF and tighten the clamps.

This kit includes an S&B Powerstack pre-oiled reusable air filter. The frequency you should clean your filter will depend on your driving conditions. It is recommended to check your filter at every oil change or 3,000 miles. If there is a build up of dirt as thick as the wire mesh, then it’s time to clean your filter. As dirt builds up on your filter, the restriction of the airflow also increases. More frequent cleanings will improve your fuel economy and your vehicle’s performance.
