3. Remove the stock airbox by loosing the clamp at the throttle body and removing the 10mm bolt in airbox. Unplug the PCV line, MAF plug and remove as a unit

5. Install the JLT heat shield by slipping it under the air inlet duct, line up the front hole up with the stud on the fan shroud and use the supplied 6mm nut to secure it to the stud, and then use the stock airbox bolt to secure it to the car.

6. Install reducing coupler on throttle body end of JLT tube and while holding the filter in the heat shield area, slide the tube through hole in the shield, into the filter and on to throttle body.

7. Remove the stock MAF sensor from your airbox using the T-20 torx driver and install in the JLT tube using the supplied screws. It will only install one way.

Plug in the MAF, PCV and automatic line (if used). Adjust tube for best fit and lightly snug all clamps.


Installation is complete, ENJOY!

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.
