BOSCH 80034 Duraterm Glow Plug - Single | Compatible with Select 1978-00 Diesel Am General, Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac

What else to say? I only did the driver side and it starts like a forest fire in california. Easy and smokey. Will do the passenger side in spring. No garage.

The spot welds holding the electrode spade to the filament stud are inconsistent at best. Some are actually welded, some require only the slightest suggestion to break the weld and fall off, and one had already broken off in the package. I will have to replace two, so if you buy these, plan on buying two extra. If you get lucky, you’ll have two spares. Outside that, the quality is good. I like the taper at the end of the filament that should help with the filament not being able to expand and distort, causing removal difficulties in the future.

Great glowplugs, but beware when shipped the blade connector broke off 3 of the 8

Would not bye again open two boxes on blowouts ends wire hook up was gone thought they was wrong ones open another box had wright end on it so I went a Head put it on, went to plug the wire on it and fell off of it so I took it back out but for some in the box and trying to send them back, they make it a hassle anymore when they sell junk you should be able to return no problem

Quick start up even below zero with my 96 6.5l diesel

They do the trick. Easy connections, common threads.

These used to be THE plug to use. It appears there is oil or other contamination on the parts when they are welded. The weld is there, but there is no penetration. You can see where the weld is flat where it met the electrical tab and stopped. I suspect more will fail in use from the vibration. I will try to get warranty on these 4, and I estimate it will take me warrantying these 3 times to get enough "good" ones to finish the job. I'm ASE master certified, I've done this job on GM and International IDI's a number of times.

The spot welded tangs on 4 of the eight injectors broke off with very little provocation. You HAVE to bend the tangs on any glow plug to keep your wires off the exhaust. I re welded the 4 that broke off, and they seem to still work, but lets see how they do long term. Also, the Champion glow plugs are JUNK. I bought 5 two months ago and 4 of them went bad. I was expecting more from Bosch for 4X the cost.
