I recently bought a 2000 ss maro with 54,000 miles on it. What is the best spark plug and wires i can get for the ls1? I heard accel was good, also what size 8.8.5? Thanks for any advice. Im newer to the forum and want to learn as much as i can.

 

I keep hearing AC Delco or NGK is the way to go... Iridium or platinum would be best, they will last the longest, but I don't think you'll see a ton of performance gain.

 

I would use the platinum at least for the last plug on the passenger side. It's a real pain in the a** to remove and replace.
