Fuel injectors

Flow
Bold denotes the rated pressure.

Spacers
2 1/2" injectors require 12mm (7/16") spacers when using the S4 intake manifold and fuel rail. If you are using an RS4 fuel rail you will need a 1" spacer!

Adaptors
Injectors are male, harness is female.

Conversions

 * 1 lb/hr gasoline = 10.5 cc/min (@720 kg/m3) (1 (pound / hr)) / (720 (kg / (m^3)))
 * $$Flow_{new}=\sqrt{\frac{P_{new}}{P_{old}}} Flow_{old}$$
 * Density of typical test fluid = 760 - 770 kg/m3
 * 1 lb/hr = 9.81 - 9.95 cc/min
 * Density of n-heptane = 685 kg/m3
 * 1 lb/hr = 11.0 cc/min
 * 3 bar = 43.5 psi
 * 4 bar = 58.0 psi
 * 5 bar = 72.5 psi

Instrument cluster
If you change fuel injectors, your instrument cluster will estimate your fuel consumption incorrectly. Use VAG-COM to adjust it by going to Instrument cluster (17) -> Adaptation (10) -> Channel (03).

Unfortunately, you can only set it to a maximum of 115%. Default is 100%.

If you have access to ME7.x tuning tools, you can completely fix cluster consumption by adjusting the KVB 1x1.
