First Gen spark plug

[96RT10GUY]

Anyone have a recommendation on upgraded spark plugs for a non modified 1st gen (8.0)?

I would NOT try to find an upgraded plug. Champion RC12LYC or RC12ECC is the required 'long-reach' plug for a reason. ****-Fires, Platinums, etc etc are a placebo, if you have good coils and wires, Champion is what U want

Thank you for that!!!
