Questions Regarding Bosch EV14 Injectors And Necessary Hardware

[PovGRide742]

Regarding Bosch EV14 Injectors in STOCK B5 S4 fuel rails:

1. What size, o-ring to o-ring, is correct... 48mm or 60mm?
2. According to this post, these injector hats (6) are these fuel rail spacers (4) are required to properly secure the injectors?

Thanks, and sorry if this has already been covered...

Look them up on eBay. FiveOMotorsports sells them for $50/piece and are cheapest I found.

52lbers.

You don't need any hats/spacers or anything.

Just USCAR adapters found here:

I run them on my car, so I'm talking from first hand experience.

I found them elsewhere for $50 a piece also, plus USCAR adapters... but I keep reading people's findings that the o-ring doesn't quite sit in the manifold using the stock clips without spacers and hats. Thanks for the link and input though!

Mine don't seem to have a problem. I didn't use clips though.

[PovGRide742]

Mine don't seem to have a problem. I didn't use clips though.

That would be why then. Using the clips causes the o-rings to not fully seat in the manifolds...

They have the same part number as everyone else's, but they come in a ford racing box. Even cts says in their description that the sell the EV 14 as oem from the GT500. Difference is that ford rates them at 37psi instead of 3 bar so they called 47lb by ford.

Also they sell the plug adaptors for $42 for 8

I have a set of 6 52lb EV14's in great shape. Send me a PM if you want them.
Also, the original Bosch o-rings on them will work, however I found the best seal to be with the OEM o-rings on the EV14s. Using the OEM clips and OEM o-rings, they seal 100% with no spacers of any kind. The OEM o-rings are a few thousandths thicker and take up any space there could have been.

Whats the correct part number for the 72 lbers? 055US750? Or are they all the same?

Also what's the difference between the wireless and those that dont say wireless?

[durfA4]

Wireless are plug adaptors that clip right onto the injector, so your ev1 harness plugs into the adaptor. Wired ones have about an inch of small gauge wire between two the adaptors

[Austonwerner4]

you need the hats if you're running the short body EV14's... the ones Rated S linked are 64mm long. You will only need to make fuel rail spacers

[AudiTechS4]

i just bought these. just want to make sure they are the correct ones
http://cgi.ebay.com/ebaymotors/_W0QQ...KQ3aMEWNXQ3aIT

[NOTORIOUS VR]

no idea.. there's no info at all on the ebay or the link on the auction...

might have wanted to check if they were what you thought they were before buying them... but either way, since 034 now makes hats even if they are the shorties you're alright if you get the hats

[durfA4]

They look like the STD 52lb injector. Same body at least. Best way to find out is wait till you get them and test fit.

Size =/= body length... the EV14's come in 3 different standard lengths.

[Highhats]

The good ones to get are not the modified EV14 Bosch all based on the 52lb injector. THey are the actual Bosch Motorsport racing EV14 injectors. I know EPL sells them EPlabs.net

[PovGRide742]

I noticed you had a picture in the thread containing the post I linked from Max@034Motorsport WITH injector hats on your EV14s. I'm assuming you have the short-body injectors then (48mm o-ring to o-ring)?

[NOTORIOUS VR]

correct... I have the ID1000's from Injector Dynamics.. they use the short body ones and supply you with the hats and plugs for the injectors

[PovGRide742]

For those who care... to answer my first question:

1. What size, o-ring to o-ring, is correct... 48mm or 60mm?

EV14 PDF
The 'Standard' EV14 is appropriate for the S4 (for those curious, the 'Compact' EV14 is appropiate for the RS4), therefore a 48mm, o-ring to o-ring, should be used if the option is given (Ringer Racing, Air Research Design).

Still I'm confused regarding spacers and injector hats. The OEM injector is slightly shorter overall, but slightly longer o-ring to o-ring (OEM is like 2-3mm longer supposedly). This causes problems with the lower o-ring not seating correctly in the manifold when using the OEM clips. The following are two threads detailing this:
* http://www.audizine.com/forum/showth...r-installation
* http://www.audizine.com/forum/showth...k-on-FT-Builds

A post in the first thread says EPL's kit came with injector hats and rail spacers. A post in the second thread, from Max at 034Motorsport, says the proper method to secure the injectors is to use injector hats, rail spacers, and the OEM clips. The following are the two posts described:
* http://www.audizine.com/forum/showth...=1#post5074107
* http://www.audizine.com/forum/showth...=1#post6779388

So my assumption is for a properly secured EV14 setup, you need 48mm EV14s, injector hats, rail spacers, and OEM clips.

[PovGRide742]

correct... I have the ID1000's from Injector Dynamics.. they use the short body ones and supply you with the hats and plugs for the injectors

Fantastic! I checked their website. Their short-bodied version is the 48mm version (o-ring to o-ring). I checked the part number 0280158117, and is displayed as the 48mm version (o-ring to o-ring).

This confirms it... Standard EV14 (48mm o-ring to o-ring), injector hats, rail spacers, and OEM clips for a properly secured setup.

[durfA4]

what is the consensus on swapping of the bottom o-ring? I just bought these and am waiting to tune.

[sweets4style]

I found someone on vortex that seems to get them for the best price.

http://forums.vwvortex.com/showthrea...or-your-dollar

You do not need any hats with his bosch ev14's and you just utilize the stock clips. He also sells injector dynamic sets and got me the best price hands down of anywhere else.

Be careful buying from him.

[beast5150]

I have a question anyone know anything about the bosche racing injectors for the b5? they are 60lb 650cc they are from what I am told a ev14 style with the ev1 clip. Am told they are better than the ev14 as far as lumpy idle or hard to tune excetera. I don't know much about them.

[julex]

ev14 have super smooth idle and are easy to tune....

[getslideways]

/\ I too have never heard anyone talk about difficulties when using EV14s. Beast5150, you might be thinking of the Siemens 60# injectors.

[vtraudt]

I want to get a handful of the 'fat' Audi O-Rings. Part number? Source?
Use the fat ones (Audi) in the manifold, and the 'slim' (Bosch) on top? (spacers come with their worn O rings).

Note: I can't see how the short EV14 can seat properly without using the 12mm spaces. While waiting on the spacers (BTW: what is the most econimical source for them?), I hacked the mounting tabs off the (1.8T, AEB) fuel rail and tied the rail down (for a few days).

Also, the original Bosch o-rings on them will work, however I found the best seal to be with the OEM o-rings on the EV14s. Using the OEM clips and OEM o-rings, they seal 100% with no spacers of any kind. The OEM o-rings are a few thousandths thicker and take up any space there could have been.

Use stock o-rings on the bottom of the injectors and on the hats, and the green ones that came with the injectors on the top of the injectors into the hats.

Thanks. Makes sense. Currently looking up sources for at least 14 (1x 6 cyl, 2x 4 cyl) for the bottoms (actually 'lost' an o ring down there; assume engine ate it), or 28.
Maybe I find a bulk box of 100 and avoid paying $0.88 plus shipping for an O ring...

Interesting, I have seen venders and different forum members who have outsourced their own injectors using different Bosch variants:
Bosch 0 280 158 117
Bosch 0 280 158 123
Bosch 0 280 158 298

Are only the bottom OEM ones thicker, or also the top? Or use Bosch top, OEM bottom?

[julex]

I've never had problems with Bosch vitons. The only time you might have issues is when you dont do anything about injector length and they are barely touching the manifold.

[Seerlah]

Just to add more content to the thread. I own a B5 A4 (yeah yeah, I know) and run EV14 630cc injectors. I redid my injector wires and canceled out the adapters. I simply butt connected pig tails with the US car connector. Much happier with it this way. If you want to keep your stock harness intact, I don't suggest you do this at all. But if you are one who modifies their car to their own liking, I highly suggest it.

My injector section of my engine harness required to be redone anyways, so I first butt connected the Jetronic type (stock) pig tails. After this was complete, I would occasionally get misfires. I knew it wasn't my butt connection, as all I would have to do is wiggle the adapter section of the injector and all would be good. But...it would happen again. Tried CRC electric parts cleaner and it fixed the random misfires for a while, but I required a permanent fix. I knew the adapters were the issue. Just too many damn connections before the injector. Redid the wires again, this time around with US connectors at the end of the pigtails and have been misfire free ever since (done recently). As mentioned before...much happier. Ordered pricey ones at first from a company I'm not really in the mood to search for again. Really nice though, and will be placed back in if I ever need that style connector (doubtful). Next time around, went the cheap ebay route. I notice the quality differences, but meh. It is what it is.

And thanks for the o-ring tip. I am using Cheap Autozone fatter ones (did the trick), but did not know OEM was fatter also. Going to reorder and replace those. Thanks!
