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.

Key Benefits

• +20% intake volume

• +2–3 HP from low to high RPM

• 40% weight reduction vs. stock airbox

• Two-piece layout with dedicated Sprint Filter support

• Quick airbox removal for easy throttle-body and spark-plug access

• Simplified filter inspection and cleaning

• Fast and precise installation

Who Is It For?

Ideal for performance-focused riders and racers looking to enhance intake efficiency and boost engine output while keeping a race-ready, easily serviceable setup using premium Sprint Filter components.
