Injectors

Stock and Performance injectors for 2004 - 2005 Chevy GMC 6.6L Duramax LLY
We carry stock replacement and high performance injectors for the 2004 - 2005 Chevy GMC Duramax 6.6L LLY engine. Signs of worn injectors may include excessive smoke, rough idle or a light "miss", low power and poor fuel economy. LLY owners can extend the life of their injectors by using Stanadyne Performance Formula with every tank of fuel. Clean fuel is very important, so changing your fuel filters at the recommended intervals is critical. Adding an aftermarket fuel filter or a FASS will also extend the life of your injectors.

Buyers Beware
We've noticed that some shops are installing new nozzles in old injector cores and selling them as "rebuilt injectors" at reduced prices. We're here to tell you that simply installing a new nozzle in an old core does not qualify an injector as a rebuilt unit. We could do the same thing if we just wanted to make a quick buck, but we won't do that because we actually believe in delivering only the best products to our customers. So just remember that if the price sounds too good to be true, then it probably is. Our common rail injectors are 100% Bosch factory new or remanufactured Bosch injectors, and carry a 1-year warranty.
