Bump, my website has been updated.

I think this should be in your sig.

I will work on that. Here is a set I did for "Laken" on this forum. These had to be the dirtiest set of injectors I have seen. I had to swap one of his from my spares to complete his set because one injector was not performing up to par.

The big improvements are between cold start smoothness and fuel economy. The butt dyno is hard to measure. Out of 6 injectors, usually 2 under perform. What happens is that they are a little lean on those 2 cylinders do the computer compensate by richening up the mixture on the bank of cylinders (cyl 1,2,3 or cyll 4,5,6).

To avoid confusion, my price is $10 per injector and $5 for shipping for all of them. 6 cylinder would be $65. My machines ultrasonically cleans the, backflowed to any particles internally in the injector, and tested to flow within 2% of each other.

Guys who have had this done: was starting improved? Telkl me about the difference, please.

Thx,

I noticed a definite difference in mine... Alot snappier

[MrConflicted]

I sent mine to WitchHunter performance who turned them in a few days. I had them back in a week. $20 bucks an injector and they flow matched them to 1.5% variance. I ran the injectors for about a day before I broke a rocker arm, but that cleaning sure made a difference in throttle response!

[bowtie2bimmer]

The replacement pieces were from napa... they had them in stock. it was 4 bucks per injector

[dano670]

I am the guy who does the injector cleaning. I made this video of my machine testing a cleaned set of injectors:

I haven't finished the website yet. More difficult then I thought.

bump, see edit above. he is on r3vlimited as well.

^ May I ask whom it is?

[butters]

Butters, who did the flow matching and cleaning on your injectors? It was mail order and the guy did a great job.

edit: Dan Stevenson, dano670 did the work, only $10/ea and $5 shipping, and he has 24v injector loaners so you don't have downtime (for those who are swapped - not on this subforum I suppose!). I'll try and find the link, but I did get to see a before/after flow test video and the results speak for themselves, it's simply the best option for refreshing the injectors.

Where did you get the kit for the little injector pieces you replaced?

[bowtie2bimmer]

and cleaning the filter at the other end... i took parts cleaner and blasted it then took compressed air and shot it in there. once the liquid started coming out clear it was clean...

[OnMy2ndE30]

So NAPA carries the rebuild kits for the injectors? Is it as simple as popping the tip off, installing new orings and popping the new tips on?
