MWR Performance Velocity Stack Kit for Yamaha YZF-R1 / R1S / R1M 2015 - 2019

MWR Performance Velocity Stack Kit for Yamaha YZF-R1 / R1S / R1M

The MWR Performance Velocity Stack Kit is a complete intake stack upgrade for the 2015–2019 Yamaha YZF-R1, R1S, and R1M. This kit includes both upper and lower velocity stacks with installation bolts, giving R1 owners a full MWR intake setup for improved airflow, sharper throttle response, and stronger performance potential on tuned street and track builds.

Designed as an OEM-style replacement stack kit, the MWR-VS-950 installs without airbox modification and is built for riders who want more than a basic filter upgrade. Supplier information notes that WSBK and BSB testing showed the MWR stack kit delivering performance comparable to official YEC stacks at a lower cost.

Why Upgrade Velocity Stacks?

Velocity stacks help shape and control the way air enters the engine. On a high-revving sportbike like the Yamaha R1, the right stack design can support stronger intake efficiency, cleaner airflow, and better performance when paired with the proper exhaust and ECU tuning setup.
