BOSCH 252cc Spridare LS1

GM Part 12555894(A)  (Bosch 0280155890) - THESE ARE NEW FACTORY LS1 INJECTORS

Note: Injector flow rates are based on testing with n-Heptane test solvent (0.6855 g/ml). U.S. EPA emission test gasoline 40CFR86.113 (0.735g/ml) flows in most common injector designs at about a 3 to 4% higher rate than n-Heptane. A ratio of 1.035:1 can be used when converting the flow specifications above.

All tests run with n-Heptane @ 20oC (+/-1oC), 3.0 Bar (+/-0.01 Bar), 14VDC (+/-0.05VDC), saturated driver with RC cutoff.

This high-impedance injector will work with all factory ECM/PCM injector drivers

ADDITIONAL INFORMATION: 

Top feed disc injectors uses small multiple holes around its circumference. The disc rests on a short chimney that surrounds a metering hole. As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.

The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.
Longer service life
High-speed disc action allows wider dynamic flow range for improved idling
Quieter operation
Revolutionary disc design resists build up deposits which can affect fuel flow.
No Fuel leakage for quicker starts

Grease supplied to lubricate o-rings prior to installation.
