I have a 3rd gen GXE where the plugs are easy to see and remove, but not sure about my 4th gen. Their appears to be cover that has to be removed before the wire terminals are even exposed. Please provide detailed info. Thanks.

1) Remove front bank rocker cover ornament.
2) Disconnect six ignition coil harness connectors. Three are found under
the ornament. Three more are found nestled among the plenum runners, in
plain view, closer to the windshield than the three which were hidden under
the ornament.
3) Loosen ignition coil fixing bolts and pull out six coils from the intake
manifold connectors.
4) Use a spark plug socket, a long extension, and a ratchet handle to remove
the spark plugs.
5) I recommend using a tiny dab of anti-seize compound on the threads of the
new spark plugs.
6) Tighten the new plugs to 14 - 22 foot-pounds.

Recommendation:
Go to AUTOZONE etc. and purchase about a 18" piece of heater hose. Put the spark plug in the end and use the hose to feed it down, waaaaaay down, to the spark plug hole. Remember, get a hose diameter that will fit snugly on the tip of the plug. Use this combination to initially screw in the plug. You can "feel" the plug screwing in much better than using a spark plug socket and it should reduce the chance of stripped threads. Yes, don't forget the anti-seize compound. Wish I could say it was my idea but got it out of the Haynes Manual. Guess it was worth the price

be careful
I changed my spark plugs about 6 months ago before winter started and I ran into trouble with the last spark plug (chamber 6--I believe). That is the one that is right abovethe PCV valve area. And darn it, I had the most horrible time getting that one out...and I wound up needing to take some of the items around top to make space for the wrench to reach...after I was done...I thought to myself--good learning experience and it'll last me a good 60K
and it'll last me a good 60K
