False Advertising - Spark Plugs

Why are you advertising a quantity of 4 but only shipping 1? This is elementary dishonesty, as Revane is aware of the quantity problem. Read other reviews.

Pros
  • New
Cons
  • Obsolete

I have all 4 original NGK spark plugs and they are amazing!

I can actually confirm that a total of *4* spark plugs came with my order. They were sold to Revain and completed by Revain. It took me a month to receive them but I received original NGK Iridium spark plugs for use in my Predator 420 CC 4 pack kart. The plugs themselves are the best money can buy and I am 100% glad I got 4 plugs at this price.

Pros
  • Sleek design
Cons
  • Interchangeability
