I was wondering if anyone knew off hand what the part number is for the Spark plugs that come with the Gm supercharger kit? I can't find my manual at the moment and wanted to order a new set so i can change them next week.

Hey, whats up Scott, I believe the AC Delco plug number is R42LTS. Let me know if you need anymore info.

Thanks man. Reading your profile your car is almost the same as mine engine wise. How many miles you have on yours?

I have about 18,000 miles on it, not a daily driven car as I use my other for work. Looking into the water/alc injection to cool the blower right now as on a day like today, it was 95, I see about 5 -5.5psi.

yeah i ordered the smc universal kit about 2 weeks ago and was hoping to get it this week so i can install it over the 4th of july weekend. I know the kit costs a little bit more than some others but they had a special at fast toys performance that you got a free progressive control included in the price. i have 60000 miles on mine with about 35000 boosted miles.

this is a part # I have from the GM manual I think it is correct not sure.

Spark Plugs - 05613717

Hope thats the right #


Thanx Charles
