Review on πŸ”Œ NGK (6325) Y103K Glow Plug: High-Quality Single Pack for Optimal Performance by Cameron Novak

Revainrating 4 out of 5

Worked like a champ my universal diesel M25 starts like a dream

They are pretty easy to install and now the engine starts straight away. I'll have to watch them for a while and see how they fare in the marine environment. Replacing the middle connector with the M25 caused some difficulties. Glad I had the tool box. One note: I found the wires connecting them were quite loose. I would check, clean and tighten these leads on your old spark plugs before replacing them with new ones. Update: I installed them over two years ago and they still work great. They seem to withstand the marine environment with ease.

Pros
  • cool product
Cons
  • something else
