Review on NGK 4177 PK8 Spark Plugs by Jesse Francilme

Revainrating 5 out of 5

Ideal for performance-enhanced engines and cheaper than OEM spark plugs!

I installed these spark plugs on my 2000 Ford Lightning. With a gap of up to 0.36 at slightly higher boost pressure levels than from the factory, the truck runs great! The previous owner said he installed a set of Autolite spark plugs in the truck and I ran them for a while before deciding I wanted to know exactly what I had in my truck. Definitely a good fork for the price and if you can get them from Revain you'll probably get them in the mail faster than you can place an order.

Pros
  • One year trial
Cons
  • Available in white only
