Anybody have review on ECS Fuel injectors?

[dalmation53]

I bought some supposely Bosch ones on amazon and the car started and ran like shit. put the old one back on and problem was fixed. i see the ECS ones are wayyy cheaper then genuine but hesitant to do the work again and they don't work properly.

Probably counterfeits then. Amazon is known for counterfeits being mixed in with genuine parts due to how they operate their fulfillment centers.


ECS branded injectors?


I would see what euro shops like fcp euro, europa parts, pelican parts, have etc if you are looking to save a bit.

Hmm....interesting. I didn't even know that was an option for DI fuel injectors. Any recommendations where to get it done? I'm more interested to know about the balancing part. The cleaning part can be a pretty simple DIY procedure, but I suppose the balancing part would need some sort of flow meter to do correctly.

RockJGC, I am perplexed by your comments given that you said you are a Audi dealership master tech in the NYC area.

Never clean injectors as you can get false positives and modified spray patterns -- always replace with new OE injectors. Places like FCP Euro are excellent companies overall for many parts but but they use WorldPac so I would avoid for critical engine parts.

Was, not am....and we never did anything but remove and replace injectors of any kind. That's how a dealership works.

I think for this stuff I would just find an online vendor like the ones mentioned.. I get all oe Audi stuff for critical parts..

Have you ever priced OE injectors? Just curious....I'd imagine they are aren't inexpensive.

[silver_tt]

They are $175 each so $700 total

That's not too bad. Who manufactures the OE part?

[silver_tt]

pretty sure it's Bosch that manufacturers the OE injector

You might be right. Not sure if these are truly OE, but the price seems really low:

Bosch is definitely OE supplier. When I replaced mine, the ones that came out were stamped with the Audi logo and part numbers as well as the Bosch logo and part number.

I would avoid buying from eBay, Amazon, etc. I would only purchase from a reputable supplier that backs their inventory. There are definitely counterfeits on the market.

Price is too cheap. places like audiusaparts sells as at a fixed margin over cost. Possible they are "real" but not tested as rigorously in QA, etc

The Bosch injectors also come with a hologram sticker and code to check if they are counterfeit but I have still seen people burned

yeah after the counterfeit plug fiasco of a few years ago , i am very leary about amazon now.

[Theiceman]

150 at genuine audi parts. id pay that and know what i'm getting.

[silver_tt]

I think it's $190 at genuine audi parts there because I believe the part number should be 06H-906-036-N. I am not a parts expert though, I always have them run my VIN to be 100% sure the parts are a match and most recent.

eBay and Amazon (especially 3rd party sellers) would be the most risky I would think... with FCP and ECS a better step up from that....I don't really need lifetime replacements for my injectors because in most circumstances they should never fail or need to be replaced. but getting it from a dealer like audiusaparts (webfront for one of the largest Porsche/Audi dealers in the USA by sales volume) would be the safest and best choice for critical engine parts

So you must be flex fuel like me! Yes - the injectors are different for the flex fuel engines (metal intake manifold).
Agree with all of the above and I would not have taken the chance had the original Audi ones not been made by Bosch.
Here are the ones I took out. Note part numbers - I had older revision J. Also note the Bosch logo on the back side.

And here are the Bosch replacements. Boxes arrived sealed with the holographic anti tamper tape as was mentioned earlier in the thread. Unfortunately I don?t have a pic of the back side.

Full disclosure - I ordered from FCP only because they had other parts I needed in stock. ECS also had them.

[silver_tt]

Ya, I am flex fuel also. I have a Q5 but it's a 2014 model year, CPMB. You are right "J" has been revised with "N" but since my injectors are original I very likely have "J"s still in there -- not sure the difference, if there is any material difference.

FCP is a good company and I have always been happy with everything I got from them. I have seen guys in the Porsche 997 forum using injectors from FCP and so far so good it seems...there was a bit of a scare when the Bosch website service was down and you would type in the code that came with the injector and it was indicating they are fake, but it turns out the service that looks it up was just down and didn't just say so.

You 100% can clean and balance injectors with a reputable shop. Tons of guys do this. I actually sent out OE injectors because flow and spay patterns can vary even with brand new, OEM injectors. When I tune, having injector flow rates greatly helps understand fuel delivery.

You have posted good information on AZ so I am not trying to discredit you but absolutely any decent professional engine builder will tell you to never, ever clean injectors and just replace them with new OE ones. I have seen on several occasions people with a new engine build that decided to clean their injectors instead of replacing them and one was leaking and took out the entire block shortly after (Alusil but still a bad injector can take out cast iron). It's not just about the flow but also the spray pattern which is especially important with DFI, as well as making sure they don't leak down. You can have injectors test PASS but in certain circumstances they are failing. Anyway my 2 cents but always just pay up and buy new OE injectors if you need them and are that far in...

I just put them (bosch) in my car while doing the carbon clean two weeks ago and they're fine...ripping it with the stage 3 tune.

To be clear on what I'm referring to:

I'm not talking about one of us cleaning our injectors with like an ultrasonic cleaner or just brake clean. I'm referring to reputable and technical shops who completely disassemble injectors, clean all the internals, test the drivers, replace filters, seals, etc. and then flow test them. They also balance and adjust the drivers so that all are firing within a percent or two from each other.

This is better than just buying new ones too.

This is the best outcome you could strive for.

So where do you get that done? I have never heard of that before, so that's why I'm asking. Like I mentioned earlier, we always removed and replaced with new, but that's the dealership lifestyle. Swapping parts left and right, up and down.

[silver_tt]

Yes, I understand you are talking about sending the injectors off to a company who cleans them. When they are being tested in a laboratory it is under controlled conditions, not in "the wild" in the real world. Especially in DFI engines that run very high fuel pressures. You can get improper spray patterns or they can leak down over longer periods (overnight) with a hot engine. Every reputable engine builder I know will not allow this if they are going to take the work....

This must be for dfi engines due to fuel pressure. This is absolutely not the case for standard fuel systems using sub 100psi. Sending out injectors for rebuilding /cleaning for pattern and matched flow rates is looked at as beneficial for performance. I have a hard time seeing how more psi would effect that and a hard time seeing how a mass production line would be the more precise of the 2. Is "the wild" heat cycles? I'm very confused by that.

[silver_tt]

Not recommended for port injection either even at 60 psi.

[87tpita]

Well now your wrong, 🤣🤣

[silver_tt]

Considering you can't even spell "you're" correctly let's just agree to disagree on this. Clean your injectors, like I care.......

🤣 that be for sure be a greate rebuittle. What is "the wild"? What is you be describing with that?

[MongoMcG]

For those confused by the english language and the use of idiomatic expressions, "the wild" (in this case) is your driveway or garage, or a service bay at the dealer, or bubba's back yard, etc. - as opposed to a highly controlled environment such as a lab. "In the wild" is a common expression akin to "in the real world". They have nothing to do with being wild nor real, but instead (in this case) are meant to infer the environment most people find themselves in when unaware of, or unwilling/unable to seek out the highly specialized environment.
Thus endeth the lesson. No, I'm not an english teacher, but I can tell you about gerunds and past participles.

[87tpita]

The idea that a fuel injector would drastically operate different in real world conditions in comparison to a lab seems mostly unrealistic. I'm aware of what he meant, I was being facetious. From what I've gathered in my short research today rebuilding injectors for dfi engines is just as safe and effective as it is on multiport injection. If fakes are a concern, have your injectors rebuilt.
