Carbon Fiber Attention for part# CFCAI127-FMG-11: This kit is made from real Carbon Fiber, which is known for its light weight and extreme strength. When tightening all hose clamps, ONLY snug them with nothing more then a nut driver or screwdriver. Even though they are very strong, it is possible to tighten the clamp too much and crack the gel coat.

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 Intake Pipe with PCV Fitting (1) 5” ID x 2” Silicone Coupler (1) 5”x9” Air Filter, (1) JLT Heat Shield, (2) 80 Clamps, (2) MAF Screws, (1) vacuum plug

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 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 supplied nut.

6. Remove the stock MAF sensor from the stock filter housing and using supplied screws install into the JLT MAF port. Be sure air flow arrow is pointing toward the throttle body end of pipe

7. Install 5” silicone coupler and clamps onto throttle body. With the filter in the heat shield, slide the JLT tube through the hole in heat shield, into the filter and then in to coupler on the throttle body. Adjust tube in and out of throttle body coupler for best fit and Remember DO NOT over tighten the clamps, they just need to be snug! *TIP* Be sure to wipe out the filter with a clean rag to remove any oil and aid in clamping

8. Plug in the PCV, Vacuum and MAF connections. If your set up does not utilize the vacuum port on the driver side of the tube, use the supplied plug to omit the fitting.

This kit includes an 5x9" 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.
