Motorcraft OEM Ford/Idi 7.3l DIESEL Glow Plug Zd-9- Zf2tz-12a342-a (Set of 8 Pcs)

After reading of other Ford IDI owners experiencing catastrophic engine failure after installing cheap GP's, I realized I was being pound foolish using cheap GP's. Now the truck starts better than it ever has, thanks to these new glow plugs. They also allow the GP controller to operate properly, applying correct cycle duration.

Arrived very late due to shipping issues, how ever when they arrived and I looked at them no question about quality and the price is amazing, I will keep them as spares for my truck as I had to buy a set locally for an 170 dollars cad due to an emergency situation. Never use autolite glow plugs in your truck, will be the worst mistake of your life, especially at this awesome price, get the proper ZD9's (Beru) and make life pleasant, I all so recommend using a bit of marine never-seez (NMCBT-8) on the threads to make life even better for the next time ! Thank you to the company that supplied them, thank you for shipping to Canada, and thank you for an amazingly fair price!

My rig was having troubles. I just replaced these and was good to go. They are as expected.

Just so people know it only took one bad glow plug to make my glow plug controller click repeatedly after cycling. These were actually way easier to install than I though with a pretty simple 1/4" drive set and extension. Make sure you cover the intake and blow all the crap out of the glow plug areas. My trucks an AZ truck so it had tons of dirt in there. It was a mess to clean out but WAY better than dropping dirt into the glow plug hole. I blew compressed air and put a shop vac where I was blowing air to try and catch some of the dirt and debris. Once that was done I sprayed some penetrating oil on the threads, scrubbed with a tooth brush and blew again. After this is about as easy as changing a seat of spark plugs on a V8 gasser.

Perfect fit and oe product. Spend the extra few bucks to get the best product!
