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

Revainrating 4 out of 5

Seems to work great, preheat 20 seconds and tractor starts with .

Fits Kubota B7100 with D750-A Diesel. The threaded portion of the body appears to be slightly longer than the original plugs, they do not screw into the top socket of the plug. The old plugs were also NGK Y103K plugs but were numbered 7712 instead of 6325. Two of the new plugs were numbered 6325 and the third was different, maybe 1563, I don't remember and don't see it now that it's installed. Seems to work great, 20 second preheat and the tractor starts with just a few seconds cranking.

Pros
  • Great for me
Cons
  • No instructions
