Race Bellmouth F-1C / F-1R AF006A-028 By ProCharger

You wouldn’t run a marathon with a snorkel on, right? Same goes for your ProCharger. If you’re rocking an F-1C or F-1R head unit, this Race Bellmouth Inlet is the airflow upgrade your setup desperately wants—even if it’s too polite to say it out loud.

Engineered to smooth and streamline airflow into your supercharger, this bellmouth isn’t just a pretty face (although it is quite photogenic, especially in engine bay selfies). It’s about maximizing performance where it counts—right at the mouth of the beast. The result? Lower restriction, better efficiency, and more power where you feel it.

This bellmouth was designed to be used with a 4″ T-bolt clamp (part number MMCLAMP-4), so make sure you’ve got one handy—unless you’re into spontaneous disassembly at 6,000 RPM (we’re not judging, but your serpentine belt might be).

Perfect for high-performance street builds or all-out race monsters, this bellmouth helps your ProCharger stop gasping and start gulping. Whether you’re chasing timeslips or just the thrill of hearing that blower scream like a banshee at full send, this simple upgrade can make a noticeable difference.

And let’s be real: there’s just something satisfying about the phrase bellmouth. Say it out loud. Now buy one. You know you want to.
