Hey guys

I got new plugs to replace my possible fouled one. The new NGK plugs have a threaded top which the red cap on my FGMT fits over. Will this connection be good enough? The stock champion plug the truck came with has no threads and a fatter top which seams to have a sung fit when the cap is placed over it.

The red cap fits pretty snug over the threaded style new plugs. My concern was the connection on the inside of the red cap in comparisson to the threaded top of the plug.

hope I didn't confuse anyone.

thanks

you will need the bit that screws to the top of the plug otherwise you will have poor spark.

Age old problem. Plugs NEVER go bad. Something else is causing the problem. You should never need a new plug!
