F1250 Fuel Filter Gears H23A (Bluetop VTEC) and F20bAn electronic fuel injector is the most precise component in a modern engine, with dimensions and tolerances measured in microns. Trouble free operation requires proper filtration; defined by Bosch as a minimum capture efficiency of 87% at 5 microns, and 100% at 35 microns. To put that in perspective, the average human hair measures approximately 75 microns in diameter. The F1250 provides this level of filtration with a pressure drop of 1. 1psi at a
