Decided to change my spark plugs and wires on my 1999 Camaro SS SLP with 30,000 miles. It had NGK PTR5C-13 and replaced them with AC/DELCO 41-162 and were told to gapped them at .040. Plugs and wires look to be stock. I changed them just because they were 20 years old and I felt the idle was off just a little. It only has a SLP lid and LM1 exhaust, no headers. Plan on keeping it this way for awhile. I hope I didn't put in the wrong plugs, could someone let me know?

Should be fine. That's the stock plug for lots of LS motors.
