Race Bellmouth F-1 / F-1A / F-1D / F-1A-91 AF006A-026 By ProCharger

If your F-1 ProCharger is gasping for more air like it just finished a 5K in the desert, it’s time to bolt on the Race Bellmouth Inlet and let that beast breathe like it’s at sea level again.

Made specifically for the F-1, F-1A, F-1A-91, and F-1D head units, this bellmouth is all about optimizing airflow and reducing restriction at the inlet. Translation: more air, more boost, more grins per gallon. It’s designed to smooth the path of incoming air so your blower doesn’t have to fight for every breath—because horsepower shouldn’t have to work harder than you on leg day.

Pair it up with our 3.75” T-bolt clamp (part number MMCLAMP-375) for a rock-solid, no-drama install. It’s a match made in airflow heaven—like peanut butter and horsepower.

Whether you’re trying to shave tenths off your quarter-mile or just flex at Cars & Coffee, this bellmouth adds a serious “don’t mess with me” vibe under the hood. And hey, it looks cool too, which we all know is at least 25% of going fast (scientifically speaking).

So if you’re looking to give your F-series ProCharger the airflow buffet it’s been begging for, this race bellmouth is your ticket to the big leagues. Get one on there, clamp it down, and let your boost live its best life.
