Main jets are the core component that determines fuel delivery at cruise and wide-open throttle, making correct sizing essential for drivability, economy and performance. Manufactured to Holley specifications, these jets provide precise fuel flow and maintain consistency across heat cycles and long-term use. Suitable for Holley modular carburettors including 2300 two-barrels, and 4150 and 4160 four-barrel models used on street, strip and marine applications.
