DLC? But they are interchangeable then. The 06 is suffering from stiction, and I've got a set of 03 so I'll clean the 03 ones and swap them out. Then clean the others.

I polished the passenger side today. It seems to run great now. The injectors buzz cleanly when the key is turned on.
I'll see how it does tomorrow morning. I'd say it was certainly worth the ~90 for o-rings and the time to do it.

Never heard of anyone using the early style in a late motor. DLC = Diamond Like Coating, smoother and lasts longer than the early style.

A little more consolidation ..........
The difference between original C94 & new C95 was internal change to clevis. Had to do with plunger suffering from side loading which then causes raw fuel to flood and enter the engine oil crankcase. Design improvements aimed at preventing scuffing.
There are no physical fitment differences between the injectors, but I would not intermingle them.
Along with the clevis re-design mentioned above (which helps prevent scuffing) one additional change below:
Change in 2004 from the 2003 design:
DLC (Diamond Like Carbon) Coated Plunger
• The injector plunger has had a DLC coating applied to it
• The coating will further increase the robustness of the injector against poor fuel quality/water intrusion and will reduce the risk of internal scuffing.
Note: This injector has different operating characteristics and can not be interchanged with non DLC injectors.
Installing the incorrect injector could cause Erratic or rough engine operation.
Something I found comparing old and new...

There was a guy on here a few years ago that picked up a 2003 Excursion for $17K when it should have sold for way more. The problem the truck was that while under warranty, one of the original C94 injectors filled a cylinder with fuel, hydrolocking the engine. As a result, it got updated to the C95 injectors, but it sat on a used car lot until he came along and bought it.

I remember this actually....

Yup, me too...I was STUNNED at the reduction in overall engine noise shortly after I added it...it didn't even take the 50-100 miles I've read about.

I'm just asking this but I've always heard about stiction but have been reading a little about it. Is it something that gets worse till the truck doesn't run or what. From what I've heard the clicking for the injectors is not as noticeable when its heating up in the morning (which mine does) and it makes it grouchy until its warm (which mine does) now I'm at 306K an mine has been grouchy probably since 140K-150K but just always passed it off as a diesel being cold natured.
