Review on Motorcraft ZD1A Glow Plug by Darrell Shreves

Revainrating 5 out of 5

Fantastic glow plugs

Fantastic glow plugs. They are best suited for your 1984 Ford IDI pickup diesel engine. They won't warp or loosen if they get too hot. They also glow pretty quickly. Here's a video of these glow plugs being tested on the dyno in the field to see how fast they light up. Very good glow plugs. Avoid others and buy these. As far as I know they are made in Germany. Check out this video of me testing these glow plugs before installing them: Locate the ZD1A film studio in the U-tube[.]
