Way2Speed Magna Flow Air Filter with Velocity Stack for Royal Enfield Interceptor 650, Continental GT 650 & Bear 650

Way2Speed Magna Flow Performance Air Filter with Velocity Stack for Royal Enfield Interceptor 650 / Continental GT 650 / Bear 650

In short: the Way2Speed Magna Flow is a direct-fit, dry nano-fibre air filter for the Royal Enfield 650 twins. It comes with a free velocity stack, flows 73 CFM, never needs oiling, and gained 2.1 HP and 2.9 Nm on a Race Dynamics dyno on an Interceptor 650.

The Way2Speed (W2S) Magna Flow is a dry, nano-fibre performance air filter made for the Royal Enfield 648cc parallel twin. It replaces the stock paper element in the factory airbox. An orange velocity stack comes in the box free, so you get a Stage 2 intake setup straight away.

What you get

• 73 CFM airflow: wider pleat spacing and the velocity stack let the engine breathe more freely, so the throttle feels sharper
• Velocity stack included: it replaces the stock snorkel and smooths the air going into the airbox (Stage 2 setup)
• Dry nano-fibre media: no oiling, ever, and no oil residue reaching the intake of a fuel-injected engine
• Fine filtration: Way2Speed rates the media at 99.99% filtration efficiency, finer than oiled cotton gauze
• Tough build: reinforced ABS frame with a metal support grid
• Reusable: blow it clean with low-pressure air and refit it. You won't need a new paper element every service

Dyno tested

Way2Speed had the filter tested on a Race Dynamics dyno, on an Interceptor 650 in 3rd gear (rear-wheel figures, SAE corrected). With the same aftermarket exhaust fitted on both runs, swapping only the stock filter for the Magna Flow took peak power from 40.5 to 42.6 HP (+2.1 HP) and peak torque from 47.1 to 50.0 Nm (+2.9 Nm). Your gains will depend on your bike's condition and the rest of its setup.

How it compares with other 650 twin filters

• Way2Speed Magna Flow (this filter): dry nano-fibre, no oiling, velocity stack included
• BMC FM01070: oiled cotton gauze, cleaned and re-oiled at service, no velocity stack
• Sprint Filter CM196S: dry polyester media, made in Italy, no velocity stack

Pick the Magna Flow if you want a ready Stage 2 intake with no oiling. Pick a panel filter alone if you want to keep the stock snorkel.

Fitment

• Royal Enfield Interceptor 650 (2018 onwards)
• Royal Enfield Continental GT 650 (2018 onwards)
• Royal Enfield Bear 650

It is a direct replacement for the factory element and needs no cutting or airbox changes. The Super Meteor 650, Shotgun 650 and Classic 650 use a different filter. If you're not sure, message us your bike model and year and we'll check before you order.
