How to Install a JLT Performance Cold Air Intake on your 2011-2014 Mustang GT

Please review complete instructions prior to installing.

Step#
1 Verify you have all of the following parts included in the kit:
(1) JLT Intake tube W/ PCV fitting, (1) 3.5” coupler, (2) 56 size clamps, (1) 4.5x9 Air Filter, (1) Heat Shield, (1) Sound Tube Cap, (1) Firewall plug, (1) Automatic fitting kit, (2) MAF screws, (1) nut and (1) Foam Plug (for use on 2013 only)
2 Gather all of the following tools needed for the installation: 5/16 nut driver, 10mm socket, ratchet, extension, T-20 torx driver, Phillips head screw driver
3 Install Tune for JLT Intake – Refer to instructions included with the Tuner.
4 If you have the strut tower bar, remove it. Remove your engine cover by pulling straight up. Next remove the stock airbox by loosing the clamp at the throttle body and removing the 10mm bolt in airbox. Unplug the PCV, sound tube and MAF plug and remove as a unit

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

6 Remove the stock MAF sensor from your airbox using a T-20 torx driver and install in the JLT tube using the supplied screws.

7 AUTOMATIC CARS ONLY: Drill a 1/2” hole 1/2” above the PCV grommet, insert Automatic grommet and fitting. See pictures below.

8 Attach coupler and clamps to the small end of the JLT tube and the air filter to the large end.
Note; part#s
#CFCAI-FMG-11; #CAI-FMG-11; CAI-FMG11-P have a 3.5x2" coupler
#CFCAI-FMG11-BC; #CAI-FMG11-BC; CAI-FMG11-P-BC have a 3.5x2.5" coupler

9 Install the coupler end on the throttle body and rotate down to sit in the heat shield and tighten clamps. The tube will sit on the heat shield gasket and the rubber end of the filter will rest on the apron panel.
CLAMPS ONLY NEED TO BE SNUG-DO NOT OVER TIGHTEN
BOSS BOSS OWNERS:
You will use the longer coupler included in your kit. Install is the same, but here are some tips and
pictures:
Install coupler onto throttle body and tighten down.
Insert JLT tube into coupler as far as it will go and rotate it down into the heat shield. The tube will rest in the heat shield cradle and the filter will sit just above the apron panel.

10 The sound tube brings engine noise into the cabin. Adding the intake will increase engine sounds and it may not be needed per your taste.
SOUND TUBE USED: If you are using this, squeeze clamp and install onto fitting on JLT tube.
SOUND TUBE NOT USED: Unbolt sound diaphragm behind shock tower and remove the entire unit. Then use supplied hole plug to cover hole in firewall from sound tube hose and the supplied cap on the fitting in the JLT tube.

11 Plug in the MAF, connect the PCV line and reinstall the engine cover. Installation is complete.
2013 2013 GT/Boss has an open hood vent that can bring water into the filter area. If this is a concern to you, we have included a plug to keep the water away from your filter and still allow engine heat to escape.
Insert foam plug into front section of your hood liner as shown. Position so there is no gap around the front and bottom edge. The foam will expand creating a water tight seal.

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 Intake Section of our website,www.JLTtruecoldair.com).
