Best plug I have ran in my 4.0 6cyl. Plug burns clean and better throttle response instantly upon installation. I have yet to see a plug work too well as these. Very pleased with purchase. Do yourself a favor and spend alittle extrA for these plugs and you won't be disappointed!!

This is not the correct plug for a 3.6 JK. It supposed to be a E3.82 which has a longer threaded portion. The E3.53 is significantly shorter than the original factory plugs. Every other website on the planet lists the E3.82 as the correct plug for the 3.6 Wrangler engine.
