Gen2 Hemi spark plugs - 07/20/22 08:35 PM
Hi guys, I don't come here much anymore so this topic has probably been beat to death but what spark plugs do you prefer for a Hemi. Mine is an aluminum 528 with Indy Legend heads, pump gas compression, 100% street car with a 1040 cfm APD 4150 carb.
I'd prefer a plug that doesn't come with the washers installed if possible. I tried running w/o the washers lately and the tubes seemed to stay cleaner inside that way.
I've been trying the NGK plugs, R5671A-7 and -9. Still doing some carb tuning but wanted to see if there's something else better for the street.
