How to Install AFE Silver Bullet Throttle Body Spacer on your 12-18 3.6L Jeep Wrangler JK; 2018 3.6L Jeep Wrangler JL

1. Remove the engine cover. Using an 8mm socket nut driver, loosen the clamps on the intake tube. With a 10mm socket and ratchet, unbolt the two screws on the front of the intake. Unclip the temperature sensor connector on the bottom of the intake tube and then fully remove the stock intake tube.  

2. Unbolt the throttle body using an 8mm socket and ratchet. (You may want to save these factory bolts in case this spacer kit is ever removed and engine is brought back to stock.)  

3. Insert the Silver Bullet throttle body spacer and gasket between the intake manifold and the throttle body. (The gasket will go between the spacer and throttle body). Fasten the throttle body assembly using the supplied hardware. NOTE: For 2012-2013 models, use the M6 x 1 x 50mm bolts and washers. Tighten to 10 Nm (89 lb/in). For 2014 and newer models, use the #12 x 2”L screws and washers. Tighten to 5 Nm (44 lb/in).  

4. Reinstall the intake tube and connect the temperature sensor. Tighten all bolts and clamps.  

5. Reinstall the engine cover. 

Your install is not complete! Make sure to retighten all bolts and clamps after 100 miles of driving.
