Great Plug
Other than getting only 30K between plug changes its worth having these under the hood.Especially when your over the 75K mile mark. I'm at 100K and the engine idles smooth and acceleration is there when I need it.

EXACT replacement for 2001 Chevy Lumina
EXACT replacement for 2001 Chevy Lumina. Pre-gapped, ready to install. However, like EVERYTHING on the Lumina, repair is a royal PAIN!!!!! As many others have said, the engine MUST be unbolted from the front/top engine mounts and PULLED FORWARD about 4-5" to access the back cylinders. I also found that unbolting the alternator [first disconnecting the - lead from the battery] and laying it on top of the engine, allowed much better access to the back cylinders as well. Used a mirror to help align the plugs with the hole. Replaced the plug wires while I had the engine moved forward.

213,000 miles
I've just installed these plugs in our 2001 Explorer with 213,000 miles. First time they were changed since new. It was time. Now, it runs great again. Always changed the oil, and filters, but waited until it needed the plugs changed. It started missing under load so I changed them. We drive 99% highway so I guess that's why they lasted so long. To bad everything else doesn't.

Great Sparkplugs
I installed these in my 2004 Pontiac GTO today. Even though Amazon states they don't fit, they do. I did my research, plus know the GM LS1 platform and these are popular in Corvettes, Camaros, and GTOs, all which have the LS1 engine. Torque specs are 11 ft lbs for the GTO. Didn't have any problems installing the plugs. I used ACDelco wires which matched up perfectly with these. I also checked the gap on the plugs and they all were set to .050 which is within tolerance for the GM LS1. These plugs have a copper core, so you will need to change them 30,000 miles.
N**!
Great for 2005 Ford Explorer
Immediately improved power and fixed a misfire in my Explorer. Noticable power increase and idle increased by 300 rpm.Went in easily. High quality.
