A4 B5 K04 fuel injectors?
The K04 will go in next week. It was suggested to install larger fuel injectors.
What is flow rate of the stock ones?
What size up should I look for? TT injectors were suggested.
From which year?
What flow rate?
Bosch model number?

At last I found the flow of the stock injectors (assuming that my car (1998 AEB engine) has still the stock): 210cc, 4 bar pressure, EV6 connector:

I called GIAC to find out the part # for the injectors.. they said they run their program with ford motorsport bosch red top 30lb 310cc injectors and the best ones you can get are the 945's... I have 4 for sale, Make an offer.. I was asking $160 for 4 like new but I'd be willing to drop a bit

Since GIAC requires to lower the fuel pressure from 4 bar (standard on my AEB) to 3 bar, I assume they haven't found a good fit that runs on 4 bar and keeps the injectors duty cycle in the range they want to see (lower than 80% (?) but higher than ??? %). Theoretically, larger injectors will just get controlled down; but I am sure there a lower control limits on the lower end.
Here is what I have (all have the EV6 connector):
A4 stock (AEB engine code, 150 hp) injectors (Bosch 0280150447) are 210cc @ 3bar (242.5 cc @ 4 bar).
TT stock (AWP engine code, 180 hp) injectors (Bosch 0280156061 ) are 317 cc (30#) @ 3bar, (366 cc @ 4 bar)
TT for 225hp, ( Bosch 280 155 811) are 362 cc @ 3 bar and 380 @ 4 bar.
(on 3 bar the TT225 would run max 70% duty cycle if the TT180 run at 80% for the same flow)
(on 4 bar the TT180 would run at 67% duty cycle vs. 80% on 3 bar for the same flow)

The Ford Motorsport/Bosch 0280150945 ("red tops") I found are EV6 connector style. My information is that my 1998 1.8T AEB engine has EV6 connectors.
I also found the same Bosch Ford Racing B-302 30# "Red Tops" with EV6 ($168.50 new).
Are yours EV1 or EV6 connector style?

I believe mine are EV1s.. the more round ones, not the thin ones.
