Plug - Cap Question on 81
Here are my thoughts & questions:
- For spark plugs, I’m leaning toward iridium or another long-life type, so I don’t have to mess with them again for a while.
- What plug part numbers, brands, or models do you guys use in this setup? What has worked well long term (quality, reliability, minimal maintenance) for stock engines?
- As for cap, rotor, wires, and ICM — I’m fine sticking with stock if those are good, but open to suggestions on upgrades if they give real benefits.
- Please no “pull it all out and replace with a new HP setup” suggestions — this is a stock car and I don’t think it would make much difference with this setup. I just want to keep it reliable.





As will any standard replacement parts such as cap and rotor. Just get good quality replacement parts such as NAPA or Standard Motor Products.
I run SMP Plug wires for instance. As good as OEM Quality and very affordable.
After 10 or 12 years you will likely think about replacement again just because of the time, not the miles. Iridium plugs will just be a waste of money.
