Improved Engine Performance with New Spark Plugs

As my tests showed these spark plugs resulted in smoother and more efficient engine performance. Consistent ignition and better fuel economy were noticeable benefits .The only downside was the slightly higher price compared to other options. Overall, a worthwhile investment for anyone looking to improve their vehicle's performance..

Pros
  • NGK 4177 PK8 Spark Plugs provide a reliable and consistent spark for improved engine performance.
Cons
  • These spark plugs are not compatible with all types of engines, so it's important to check compatibility before purchasing.

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
