RS4 injectors OEM or Factory

My question for you guys is, if i should buying the factory injector or should i just buy the OEM ones that are offered on eBay. and has anyone had any bad experience from buying injectors on eBay or OEM injectors? thanks

OEM = Original Equipment Manufacturer, the stuff that the factory uses.

if youre on a k03, use oem
if youre on a k04, use s3
if youre on a bt, use rs4

oem and s3 have a wide spray pattern (s3 will work without a tune on a k03, but its pointless cause theyre the most expensive) and wont cause a black bumper, but the rs4 injectors spray a little different and WILL need a tune. imagine a normal wide spray from oem or s3 and cut it in half... thats how the rs4 looks when it sprays. it can put more fuel to the engine, but it will cause a black bumper too.

in short, the rs4 is a waste unless your motor is around 400hp+. go with the oem unless your motor is lightly tuned, then go s3. if you go with the rs4 and your motor isnt at or above 400hp, then it will just cause a black bumper and youll prolly lose hp if you had went with the s3.

hope that makes sense

no, revo tunes will be tuned for s3... unless you get a stage 3 tune, but thats a stage 3... bt, not a k04.

youll benefit more from stock injectors and will prolly have rough idles running rs4 injectors... also the ugly black bumper

well they lied. the stage 3 k04 you use s3 injectors. if you get a bt, you use rs4. you said you was running k04, so you should use s3.

yes it says

Injectors; Please consult with your Revo support office or specific vehicle listing for your region for injector specification

and i did they said its rs4 and my local revo also said the same thing.

injector choise is not what i was asking. what i was asking is should i buy my injectors from the dealer Audi so its from the factory or should i just get the injectors without the audi print on it (OEM)

They didn't lie, US market Revo k04 cars call for RS4 injectors. I would make sure to change oil at 3k as you'll likely wash more fuel down the cylinders with those injectors.

you should check your facts, revo uses RS4 injectors for north america. i would recommend to the OP not to go revo k04 as there are some problems with the tune (long term problems) that revo has yet to fix. Im switching from revo to unitronic shortly as they have a RS4 injector file that was created for certain ECU numbers.

Could recommend OP sell his car, because he doesn't realize OEM=Factory.

ok factory is when you buy the part from the dealer.

and oem is when you buy the part from like IMC or napa but they part is made by the same manufacture as who makes the same part for factory just with out the vw and audi stamp on it. and which i was wondering if anyone had bad experience with it.

and the reason I'm getting revo is cause i already have there stage 1 and i was just going up stages.

no, oem will have the audi stamp on it. if not then it isnt oem and is either a cheap aftermarket part or expensive one... either way, aftermarket. ive bought a few oem parts for my gti and all have either an audi or vw or both on them.

i was gonna go revo too but then i heard about all the problems. an apr tune is faster but cost a little more, but it also has free upgrades (i think). revo is tempting cause i can get a revo tune right down the street but apr tune i gotta drive a little ways. ill prolly still go apr in the long run. as for revo needing rs4 plugs, thats for 2+, 2 you just need s3. rs4 plugs are cheaper and if you are gonna go for a 2+, id just get them. but a stage 3 tune i would defiantly get rs4.
