About 13 - 14 Ω.
Injector test bench and cleaner.
Otherwise, install them, set up the engine for normal operation, pour a 20 oz. jug of Chevron TECHRON in the fuel tank and fill with a 93 octane Top Tier gasoline. Go for a long drive, including some aggressive "engine exercise' with its high power demands and fuel flow rates = Clean fuel system.
Google "top tier gasoline" and "chevron techron" for background info.
