Can someone verify? ACDelco plug 8#41-110 12621258
I see that a lot of people are using the ACDelco 41-110. Looking at these posts I see most are from 2015ish.
Can someone verify that I have the correct plug? Going in 1998 C5 Corvette. The plug appears to be approx .17" longer from the base to the tip of the spark ground arm than what I am replacing.
Be careful with those. A longer plug may hit the piston. You may have to index the plugs away from the piston so the ground strap doesn't hit. Unless you know for sure that those plugs have worked in an identical motor as yours, stay away from them.
GM recommends, for a 1997-2000 Chevy Corvette with the 5.7L Vin G, the Double Platinum Spark plug #41-962 Gapped at 0.040" as the primary replacement. Secondary Replacement being the Rapid Fire plugs #6 gapped at 0.060" and the cheap conventional plugs would be the #R42LTS gapped at 0.050".
They do not list the #41-110 Plugs as a replacement plug. Now they are the same heat range as the #41-962, heat range 5, I would still stick with the #41-962 and gap at 0.040".
