Default New Plugs

My first time here. I just bought a '03 Zo6 and am about to change the plugs (they're original). Any tips on the best plug to buy or any problems I might encounter? I hear #7 is a bear.

I've always used NGK TR55's on all my LS1 cars. I would also recommend the MSD wires. They look good and get the job done.

Plug #7 is tricky. Get an extension and move most of the stuff in the way to get to this plug easier. Good luck.

Iridiums and red wires from Gene at GMPartsHouse. #7 is not that bad.

I'd recommend AC Delco Iridiums and the GMPP red wires - get them from Gene at gmpartshouse.com.

Buy a spark plug wrench that has a flexible knuckle on the end and it will make your job MUCH easier. Don't be afraid to tackle it, #7 just takes a little patience and be sure to pull the vacuum tube off the brake booster and move it to the side I ordered my plugs and GM performance wires from Gene, you can't beat his prices and service.
