Review on Motorcraft ZD18 Glow Plug by Craig Nelson

Ive been using this automotive part for years, and it never fails to impress me. Based on my experience, it's one of the most efficient and reliable glow plugs in the market .It significantly improves diesel engine performance especially during cold weather. The only downside is that it can be a bit pricey compared to other options, but it's definitely worth the investment in the long run..
