Anyway, one thing almost everyone agrees on is that GM made a solid ignition system, no real need to try to improve it for 99% of us. That being said any of the “lifetime” wire sets made for a GP will work just fine, I personally stay away from the universal sets. And the spark plugs also don’t make much difference unless you’re knocking. NGK TR55s or AL606s would probably serve you well.
