Review on Sierra International 18 4226 Drain Plug by Greg Wilkerson

Revainrating 3 out of 5

Worked but quality TBD

Bought to replace the drain plug for a Mercruiser 5.0L EFI. These plugs did the trick as I had a couple of old cracks when I removed them at the end of last season. Being plastic they will become brittle over time so I would recommend changing the spark plugs every few years. I wish someone would make a brass version of these plugs. Given the price, I hope they last at least a couple of years.

Pros
  • Test results stable
Cons
  • Could have chosen a newer model
