Easy to install

### ⭐⭐⭐ Doesn’t last long
*by J***N on October 24, 2024*

They worked great for roughly 6 months and now are fowling out

### ⭐⭐⭐⭐ worked fine some small issues
*by T***A on August 30, 2022*

check the threads on ALL of your glow plugs, old ones & new ones. 3 of them had to be re tapped ever so slightly. and yes all ports were cleaned thoroughly. the nuts are 7mm on new & 8mm on old and easy to lose. took about 3 hrs for all 8. wheels off fender liners, inner cooler tubes
