Got to order a few things from summit and was gonna try some Autolite AR94's but they're non resistor plugs. Any downsides? Thanx

Resistor plugs provide a hotter and longer duration spark than non resistor plugs. Non resistor plugs probably generate some radio frequency interference also, which is bad for any electronic controls (pcm) near them.

they do disrupt electronic devices within close proximity. We have a 454 on a center pivot and it had non resistor plugs (accidently) put in it instead of resistor plugs and it screwed with the pivot controls and it wouldnt run. the engine was about 10-15ft from the pivot controls

I run non-resistor plugs, noticed no difference but most of my wiring is shielded.

Is there an advantage with non-resistor?

I run non-resistor plugs. Autolite 3923's. They are a little cheaper. Autolite AR3923's (resistor) are $3.50 each or $28 a set, and the regular 3923's are $1.50 each or $12 a set. Didn't notice a difference in performance between them.
