Need spark plug information for my '03 KJ

[auburn4193]

If anyone has a factory service manual or anyone with a 2.4 engine, what spark plug gap is required for the 2.4? I have heard .040 and .050 but I can't seem to confirm either. I want to change my plugs and wires this weekend. I have heard to use either Champion or Autolite Platinum Plugs.

.040 is the correct gap for most KJ's.

AP5263 That is the autolite plat part number.

look at the sticker on the top of the radiator. it says it one there somewhere

Calls for .048-.053 gap ( Direct from the Factory service manual )
Plugs it calls for a Champion plug RE14MCC5
But an Autolite would work as well just have them cross reference the number

Yes, do this since yours is the 2.4L as you said. It should show the plug # and gap on the emissions sticker. Could be different than the 3.7L.
