Sourcing Fuel Injectors

[caliizaktiv]

Whose got leads on injectors? Hitachi's are NLA and Audi's are $220+ each nowadays. Looking at nearly 2g's just in parts...times are rough.

[Gunnarrrrr]

if you’re still paying full msrp for oem parts idk what to tell you man. A quick google turns up 1300 shipped from europe, or 1500 after tax from the usual sources most of us use.

Fuel injectors aren’t really something to mess with, i’d stick to genuine audi. If you can afford it. But, you do have an RS4 so i’m assuming you can.

At the very least track down some hitachis. I was able to locate a few stores that still have them on the first google results page.

Yes I've been searching for info on those Bremmen injectors and can't seem to find any input/reviews on them. I may proactively purchase a set. Are the Hitachi ones the best, or the OEM Bosch ones? FCP euro sells both.

[Kenny147]

Bosch are not OE for the RS4. OE for Audi injectors is Hitachi. You’ll probably find them with the Audi logo scratched out, so there’s no reason to buy them from Audi. Don’t even think about Bremmen.

[sti2relaxxin]

Thanks for the input Kenny147.

[caliizaktiv]

Thanks. Like many other things, it's a bit of price shock seeing as I paid $75 each for the Hitachi's a couple years ago. I won't be using Bremmen but I'm sure many will at their price point. Bremmen doesn't even have a website and is seemingly some offshoot of ECS.

[sti2relaxxin]

I agree. I've never had a car that was old enough to not have readily available parts at normal prices. This is a new exercise for me sourcing wear item parts before they become "NLA", and paying stupid prices for things that will soon go out of production.

[Gunnarrrrr]

bremmen is like the ecs house brand that they’re too embarrassed to put the ecs brand on. on par with uro parts imo, and just as sketchy.

Have any of you had their original injectors cleaned/refurbished? If so have you had good results?

[blackincali]

These have been a PITA to source. I'd talk to a guy named JimmyBones on here. He sold me some rebuilt injectors.

Is the main reason for proactively replacing fuel injectors the fear that one of them will stick open, fill a cylinder with fuel when the engine is off, and bend a rod when you try to start the car? I remember that being a concern when I had an E60 M5.

Thank you very much for the recommendation.

I have them on my website. The RS4 injectors are the first option.

Isn't the main reason for proactively replacing injectors the fear that one of them will become stuck open, fill a cylinder with fuel when the car is off, and result in a bent rod the next time the car is started?

I ask because, would installing "cleaned" injectors be at all helpful for preventing the leaky injector issue? IE, I'm assuming that the cleaned injectors are just factory injectors that have been serviced to ensure that they are performing per factory specifications, but if those are just used injectors that have been cleaned and tested, how is that any better than already-installed injectors that periodically get some Seafoam and are otherwise working properly?

Mainly asking because I'll be having a carbon clean done and am wondering if injectors really are worth doing proactively, and at the same time as the carbon cleaning.

The main issue with getting your injectors refurbed, is confirming they’ve been tested at the higher psi that the RS4 runs at. As far as replacing them is concerned, there have been more than a few well documented instances of engines going bang at somewhere between 70-100k miles because of a faulty injector. Considering it’s nigh on impossible to get a new engine and the last new short block I saw recently, was being advertised at $15k, I’d do it.

Thanks for the info. That sounds like a pretty convincing argument to spend the money on the injectors if doing a carbon cleaning.

In the interest of checking injector health, I looked up the fuel trims in VCDS and came up with these numbers:
Adaptation (Idle) bank 1 sensor 1 -1.5%
Adaptation (partial) bank1 sensor 1 0.4%
Adaptation (Idle) bank 2 sensor 1 -0.8%
Adaptation (partial) bank 2 sensor 1 2.3%

I'm not sure if those numbers are good, bad, or middling.

I second Kenny147 on the replacement. As for non-OEM or non Hitachi, as stated before, no go there. Not worth the gamble. When I did mine awhile back, (time to do them again) I went with OEM just for the peace of mind that if one failed, there is a one year warranty on them, so I figured if there was an injector failure, the engine would be covered by Audi. If something else went in, not likely to happen. This may be far fetched, but, as I said, peace of mind. And Jimmy, wow, haven't seen your handle in a long time.

Thanks Jimmy Bones for providing these rebuilt injectors tested to meet the pressure demands of the RS4. I will definitely be purchasing a backup set off of you once I have my new set of Hitachi injectors installed.

[Kenny147]

Fuel trims look fine. AFAIK, the trims don’t really tell you anything about the injectors but more so, how much fuel is being added by the ecu to the air/fuel mixture.

There is a way to test the injectors by using VCDS to see how much the fuel pressure drops after the car is switched off but I’d need to find the info and I’m away from home right now.

I bought from ECS and they aren’t OEM. They sell the same injectors you can get from Amazon for $80 set of four.

Please keep in mind the Bremmen injectors are not recommended due to them being low quality. I ended up purchasing OEM Hitachi injectors from FCP, and plan on having my existing injectors refurbished by Oakes Performance Solutions once the new ones are installed.

europaparts just got a fresh batch of Hitachi's. $140 a pop. Get while the goings good.
