Choose the size for your engine: Physical compatibility does not make #112 the correct stock or tuning size for every vehicle above. Jet selection depends on your engine, intake, exhaust and operating conditions. This is an SI main jet, not an idle jet or air-corrector jet, and is not intended for SHA, SHB, PHBG, CVK or Keihin jet systems.
