Jenvey Tapered Air Horn 51mm x 90

The Jenvey Tapered Air Horn 51mm x 90 (AHT51X90) provides a smooth bell-mouth intake for a 51mm throttle body, adding 90mm of runner length to help airflow and tuning.

Designed and manufactured by Jenvey Dynamics in the UK, the specialist behind some of the most respected individual throttle body systems in motorsport.

Key Features:

• Spun Aluminium: Formed from spun aluminium for a smooth bell-mouth profile at a very low weight.
• Length Choice: 90mm length helps tune the intake runner to suit your engine's power band.
• Tapered Outlet: 4.5 degree taper at the outlet matches the standard Jenvey throttle body taper for a smooth transition.
• Lightweight: Very light, so it adds little mass to the throttle bodies.
