Review on ACDelco 9628M Professional Spark Plug by Matt Patnaik

Revainrating 4 out of 5

Good quality - here is the length

I have the model 350 with HEI and ram horns. I wanted to route the new cables under the exhaust just like the current ones. This kit wasn't enough for that so I had to send them back. If this information had been available beforehand, I could have avoided it. Therefore I give the lengths below. I ended up using AC Delco 9088 wires designed for a mid seventies Vette with HEI. They worked great, a few wires were a bit long but still manageable. I will include the length of these wires in my review. 1/4" (x2)40-3/8"

Pros
  • Conductor, wire length and gauge help maximize spark output and protection
Cons
  • Available in black only
