Review on Champion RES8WYPB3 Spark Plug IRIDIUM by John Hill

Revainrating 5 out of 5

Direct factory replacement

I needed a fine tune and my mileage has been reduced. After changing the filters and spark plugs, I noticed a 3-4 mpg increase in fuel economy. As this is for a Ford F150 truck, that's a big step up. I also have more power so I would recommend them to anyone who needs to change spark plugs in their truck/car.

Pros
  • Certified
Cons
  • Cable is shorter than other picks
