Gabro Racing Evo Race Airbox Kit for Aprilia RS660 & Tuono 660
Upgrade your Aprilia’s intake system with the GRT Evo Race Airbox Kit!
Overview
Developed by the Gabro Racing Team in collaboration with DMZ Engineering, the GRT Evo Race Airbox Kit brings race-proven performance to the Aprilia RS660 and Tuono 660.
This latest version maintains the same competition-tested design while introducing a new two-piece construction with a dedicated filter support, engineered specifically for:
Sprint Filter PM176S Sprint Filter 660 RS Tuono PM176S for Aprilia
or Sprint Filter PM176S F1-85
Please note: filters sold separately.
Performance & Design
Built to perform reliably throughout an entire race season, the kit delivers exceptional gains on both stock and modified engines, including those fitted with Akrapovic or SC-Project systems.
Key performance advantages include:
-
20% increase in post-filter airbox volume
-
+2–3 HP across the entire power band
-
40% lighter than the OEM airbox with a Sprint filter
Using the fuel tank as the airbox lid, the system seals with an O-ring to maximize internal volume and maintain strong pressurization right above the velocity stacks.
