Review on Improved BikeMaster Spark Plug Guard by Michael Tran

Revainrating 5 out of 5

Fits NGK C8EH-9 Spark Plugs

This guard is more suitable for NGK C8EH-9 Spark Plugs (7473), but NGK spark plugs come with a small cardboard tube to protect the electrode and gap ( see Photo ) that can be inserted into the protector to keep it from rattling inside. The protector looks solid and seals well. It must be completely submerged in water to allow moisture to penetrate.

Pros
  • Free for educational use
Cons
  • Many things
