Gather all of the following tools needed for the installation:
5/16 Nut Driver, 10mm Open End Wrench, 11mm Open End Wrench, Phillips Head Screwdriver
Remove the factory Air Box Assembly from the throttle body to air box.
Unbolt your Mass Air Flow Sensor from the filter housing, and install the MAF filter adaptor using the supplied MAF gasket and bolts shown below. Do not reuse the screen BOLTS GO THROUGH MAF AND THREAD INTO ADAPTOR.
Add the coupler, reducer, clamps and MAF to the tube and leave clamps loose for adjustment.
Install heat shield onto the MAF adaptor and add filter. Position it so the MAF is in the stock position and tighten clamp to hold shield tight. Use pressure on the filter to “sandwich” the heat shield in position.
Note: Keep the MAF in it’s stock rotation. Meaning, remember where the plug position was stock and return it to the same position.
Tip filter in first and lower down onto throttle body. Tighten clamp at throttle body, make over all adjustments and tighten remaining clamps. FINGER TIGHT ONLY
Connect the IAC, PCV and vacuum lines now. Use a little oil on the grommets to help with the hoses. Use supplied vacuum line.
Remove IAT sensor from the stock tube and install in the grommet in the bottom of the JLT tube and plug it in.
Plug in MAF and you are done.

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.
To properly clean your filter, we recommend the S&B Precision Cleaning & Oiling Kit (located in the Parts Sold Separately Section of our website, www.JLTtruecoldair.com).
