PMO Carburetor Jet Set — 46mm Tuning Assortment | Air-Cooled Porsche 911 / 930 (PM-O852-0)

Jetting is where a carbureted engine is actually won or lost, and you cannot tune what you don't have on the bench. The PMO 46mm Carburetor Jet Set (PM-O852-0) gives you the range of jets to dial 46mm PMO carburetors to your engine, your altitude, and your fuel — instead of ordering one jet at a time and waiting a week between test runs.

Features

• An assortment of jets for tuning 46mm PMO carburetors — change, test, and change again in the same afternoon.
• Lets you compensate for altitude, fuel, cam, and exhaust changes rather than living with a factory baseline.
• Made for the 46mm PMO carburetor family specifically.
• The difference between a car that runs and a car that is tuned.

Fitment

Confirmed: 46mm PMO carburetors fitted to air-cooled Porsche 911 and 930 engines.

Match the set to your carburetors: 40mm carbs use PM-O850-0, 50mm carbs use PM-O854-0. Jets are bore-specific — ordering the wrong set means none of it fits.
