Speedwerx - High Flow Intake Kit // 2025 Arctic Cat ZR / RIOT / M 858 C-TEC2 

Our High Flow Intake Kit is key to unlocking maximum power and performance on the 858- we are seeing a 5hp gain by opening up the restrictive stock plenum! Includes billet aluminum adapter with rubber seal, 3 Frogzskin vents, and installation instructions.

Preliminary testing has shown a 18hp gain with the Speedwerx Pipe, Y-Pipe, Stealth Head, and Air Intake with no ECU tune required at high elevation!

We will be offering our Exterminator Kits for a complete package that include these parts plus an ECU Tune and Hypershift Clutch Kit for maximum power and performance in a bolt-on kit.
