Thank you for purchasing our product. We hope you are satisfied with the look and performance. If you have any questions, please feel free to call. Take your time and it will be a smooth install.

A tune specific for this intake is required when installing this kit. Failure to add a tune specific for the JLT intake may result in major engine damage. ***DO NOT INSTALL KIT AND DRIVE WITHOUT A TUNE! ***

Please review complete instructions prior to installing.

We find it easiest to install the kit as a complete assembly; however, it can be done one piece at a time. Here is a walk though:

1. Verify you have all of the following parts included in the kit:

(1) JLT Carbon Fiber or Plastic Pipe with PCV Fitting and Vacuum Line Fitting, (1) 5” ID x 2” Silicone Coupler, (1) 5”x9” Air Filter, (1) JLT Heat Shield, (2) 80 Clamps, (2) MAF Screws, (2) Stainless Strut Tower Brace Spacers If package was purchased: SCT Tuner

2. Gather all of the following tools needed for the installation:

5/16 Nut Driver, 10mm; 13mm Socket and Ratchet, #20 Torx Driver, and Phillips Head Screwdriver

3. Install Tune for JLT Intake – Refer to instructions included with the Tuner.

4. Remove the strut tower brace and stock intake from the throttle body to the airbox. There is only one bolt on the airbox and the clamp at the throttle body.

5. Install JLT Heat Shield using the stock air box bolt and ABS mounting bolt

6. Remove the stock MAF sensor from the stock filter housing and using supplied screws install into the billet JLT MAF port.

7. Install 5” silicone coupler and clamps onto throttle body end of JLT tube. With the filter in the heat shield, slide the JLT tube through the hole, into the filter and on to throttle body

8. Plug in the PCV, Vacuum and MAF connections. Adjust tube in and out of throttle body coupler for best fit and DO NOT over tighten the clamps, they only need to be finger tight.

9. Due to the size of the JLT, variances in cars and variances in intake bodies, fitment under the brace may be still a little tight. To help with this we have included stainless spacers to go under the strut tower brace on each side. This will gain you another 1/8” inch. Use the supplied spacers and re-install the Strut Tower Brace at this time.

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.
