After being a Toyota tech for 28 yrs. I am a big fan of Denso plugs (I think they still make plugs for Accel). I run Denso in the McCandless-built 383 in my sons Charger and in my '00 5.9 Durango.
Used to be a nothing-but-Champions-in-a-Mopar guy until they became so hit or miss with their quality.
Just my twocents .
