Looking For Spark Plug Recommendations

[floorit426]

I'm looking for recommendations, for spark plugs. It's a stock compression 426 Hemi, with a long duration cam and an FBO system. All these years I've been running Champion N10Y and N9Y plugs. I'm just wondering if there is a better option out there.

Have not had a Hemi but after dealing with repeated fouling of correct heat range Champions in a mechanically sound 383 I switched to Autolites and never looked back.  I understand NGK are good but don't know about in a Mopar.

I've had good luck with ACDelco, NGK and Autolite. Accel too in the old days.

Champion & Autolite have always wored well for me , NGK are finiky get them slightly fouled & they will never work again
