WellmanGlow Plugs Diesel Fast Start (Set of 8) compatible with 2001-2004 Chevy GMC 2500 3500 6.6L DURAMAX LB7

Went in great

Put them into my 02 lb7. So far they've lasted 3 years, and 30k miles without issues.

These are working just fine. I replaced all of them since I was doing a head gasket repair. Only really needed the one that the nut twisted off the threaded end. Now we have 7 spares.

Form, fit, and function are just like OEM. But all 8 only lasted about a year (OBDll codes and checked resistance - should be less than .1 ohms but all 8 are now 1-.9 ohms). And in that year I only put about 6K miles on my truck. Replaced with auto parts store purchase with 2 year warranty - we'll see.

Very well made plugs and fixed my glow plug circuit A problem on my LB7.

my husband used these and appears to do the job

Looks good, but they did not last more than 3 month. Oh, and warranty of one year WAS NOT honored. Also, so much for the amazon a-z warranty claim. That does not help.

Great deal
