1997-2003 Ford F-150 & Expedition JLT Ram Air Intake Kit Installation Instructions
Please review complete instructions prior to installing.
Step#
1 Verify you have all of the following parts included in the kit:
(1) JLT painted pipe with IAT and PCV fittings, (1) Rubber Reducer w/ clamps, (1) Rubber coupler w/clamps,
(1) S&B 4×12” Oval Air Filter, (1) MAF Adaptor with bolts, (1) Wire Harness Extension Kit,
(1) Wire Harness Extension Cover, (1) section of 3/4” hose, and (1) section of 5/8” hose
2 Gather all of the following tools needed for the installation: 5/16 Nut Driver, 10mm Open End Wrench, 11mm Open End Wrench, Wire Cutters/Strippers, Regular Screwdriver
3 Remove the stock intake from the throttle body to the air box
4 Disassemble the stock air box in order to remove the MAF sensor.
5 There are 4 bolts holding the MAF sensor in the air box. Unbolt the MAF and pull wire harness through the hole. Once the MAF is out, bolt the JLT supplied Billet MAF adaptor to the MAF with the supplied bolts.
6 Install the reducing hump hose onto the JLT pipe. This is to connect to the throttle body. Note, the larger fitting on JLT pipe will be closest to the throttle body.
7 The remaining rubber coupler will connect the JLT pipe to the MAF assembly. Connect this now along with the filter.
8 Pull the IAT sensor from the stock inlet pipe and install into the hole in the JLT filter. It will fit a little loose, but this is not a problem.
