Review on NGK 5545 Iridium IX Spark Plug - DPR9EIX-9, 4 Pack: Unleash Optimal Performance! by David Stover

Revainrating 4 out of 5

Expensive but for a single cylinder what a difference!

I have the best technology I know of as I only have one large cylinder and I wanted to get the best bang for my buck! Def noticed an increase in performance over the original 17,000 miles on the stock NGK fork.

Pros
  • Ignition parts
Cons
  • Available in white only
