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

Worked like a charm! 30yr old diesel runs like a champ.

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!

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.

OEM...always the best. We have two service trucks that use these, and they definitely helped with starting over the after market ones we tried.

Exactly what I was looking for and a great price great seller.

Over pricedI give 4 star because item does work.

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

Motorcraft glow plugs are the only way to go. Don’t skimp on these. All glow plugs go in easily. But many of the cheaper brands develop swelling at the tip and require extensive measures to remove.
