My original plugs were 41-985 which have been replaced by 41-110. Actually, GM usually suggests using 41-162 platinum plugs in cars 5+ years old instead of these iridium plugs. This has caused some confusion as to why. From what I can tell researching this, it is because the platinums aren't as expensive to make, and they don't expect older vechicles to last another 100K miles that the 41-110 is rated for. I keep cars forever so went with these 41-110 iridium plugs. desertcart sells genuine 41-110 plugs at a great price. The ones I got had consistent, correct gaps (0.04" for these) - do not try to adjust them or you could damage them - and looked a lot like the 41-985 plugs I took out, which still were in remarkably good condition and probably would have done fine another 50K miles! Warning: Beware getting your plugs elsewhere! Before finding these from desertcart, I purchased a set claiming to be ACDelco 41-110 that were counterfeit. They were packaged in boxes with the ACDelco logo and the plugs were even marked ACDelco and Made in USA, but I later confirmed they were counterfeit plugs made in China. They also had different UPC codes on the boxes, and the outer electrodes didn't have a little metal circle at the spark point. Also the little center electrode, while similarly tapered, was fatter than on real ACDelco plugs. The fake plugs came in a box of 8 - genuine ACDelco now only comes in boxes of 4, or individually. The counterfeits had gaps ranging from 0.034 to 0.048. There are a lot of fake ones out these, so be careful! They usually won't last long or work as well and could even damage your vehicle. Installation tips: Installation isn't too bad for most DIYers. Replacing these in my 2007 Express 350 Passenger Van required taking off the glove compartment (4 hex head screws) to pull the inside engine cover off (4 latches). Push it to one side to access the plugs, though the front 2 are easier to get to from under the hood, after removing the coolant overflow reservoir (one bolt). I used a 5/8" spark plug socket, 3/8" ratchet wrench, a 1.5" extender and a locking 3" extender (which helps to get the socket back out after tightening a plug). Be careful and slowly wiggle the boots/wires off the plugs so you don't break the wires. I used 2 hands when I could, one on the metal sleeve part of the boot. Everything looked nice and clean so I didn't use any anti-seize or dielectric grease but some like to do that. Be careful not to push any debris into the plug hole or overtighten the new plugs. There should be a little click feeling when the boot is properly reseated on the plug. Takes about 1.5 hours total. Good luck!
