White smoke? Hard Start? Missing or ticking noises? No start at all? It could be that you have 1 or more bad injectors. This is an OEM direct replacement injector remanufactured by the original manufacturer, Bosch.

Injector failure on the LLY or LBZ Duramax powered trucks is usually caused by either bad fuel or the use of power adders that increase rail pressure. Bad fuel can cause injector failure immediately, pressure boxes will cause failure over time. The best insurance against bad fuel contamination is to run a 2 or 3 micron aftermarket fuel filter in combination with a water separator. For those of you that want to add filtration AND increase the fuel supply, we offer pumps from FASS, AirDog (PureFlow) and BD.

BOSCH ADVANTAGE:
The advantage to being rebuilt by Bosch is they have the ability to completely "gut" these injectors from input to output to ensure they are as close to new as possible. The only "Remanufactured" part of these injectors are the housing. All internals are brand new and then reassembled the right way by Bosch. There's no reason to pay enormous costs at the dealer. True Brand New Injectors are not available except for directly on a new truck. If you can get a Brand New Injector, the cost is usually about $800-900 per injector.

WARRANTY:
Two Year, Unlimited Mileage

IMPORTANT NOTES:
  • Priced per injector. If you need a set, you will need to purchase 8.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.

5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

To small
I had to ship back because the first step I took i knew they were to tight. Great looking casual shoe that I might revisit in a larger size eventually.
