TopAir Pro Maglock Adapter System for STILO Helmets

The TopAir Pro Maglock Adapter System is a stronger, more serviceable solution for connecting a STILO Top Air helmet assembly to a Maglock/FluidLogic helmet air system.

Factory and aftermarket Top Air connections are often bonded, glued, or epoxied to the polycarbonate duct. That works, until it doesn’t. In off-road racing, helmet air connections get pulled, bumped, loaded by hoses, packed with dust, and cycled over and over again. The TopAir Pro system is designed to replace that fragile connection point with a more robust mechanical adapter.

The system uses a two-piece design: an internal nutplate and a top adapter that sandwich the polycarbonate Top Air duct. Once installed, the adapter can be removed and replaced with basic hand tools, allowing the helmet air connection to be serviced or swapped without reworking the entire duct.

The adapter body is made from carbon-fiber reinforced nylon and secured with 6-32 black oxide coated stainless hardware. The exit angle has been refined through real-world race use and tested over thousands of off-road miles.

Two versions are available:

Maglock Adapter
A clean, compact adapter for connecting the STILO Top Air duct to a Maglock/FluidLogic helmet-side air connector.

Maglock Adapter with PCI/STILO Comms Mount
Includes an integrated comms cable mount designed for the PCI/STILO adapter cable, plus stick-on cable clips for routing the cable up the side of the helmet. This keeps the comms connection near the Maglock air connection, making helmet hookup quicker and helping prevent the comms cable from bouncing against the side of the helmet.

The comms mount is built directly into the adapter body and cannot be added to the base version later.

Compatibility:

Designed for STILO helmets using the Top Air assembly, including ST5, ST6, and WRX helmets in large and small shell versions. Directly fits Maglock/FluidLogic helmet air systems.

Installation Note:

Installation requires removing the polycarbonate Top Air duct from the helmet, drilling the duct, installing the internal nutplate, and reinstalling the duct with the included VHB tape. This is a straightforward install for experienced racers, race teams, and helmet prep shops, but it does require modifying the Top Air duct.

Included:

TopAir Pro adapter body
Internal nutplate
6-32 black oxide coated stainless screws
VHB tape for reinstalling the Top Air duct
Stick-on cable clips, included with comms mount version only

Not Included:
