Snow Performance + ECS BOV for your BMW E9X 335 N54

Most 335 N54 owners are taking advantage of finally having an engine worthy of modifications from BMW.

Start by getting rid of the weak stock diverter valves and upgrade to an ECS blow off valve kit to handle all boost levels reliably. Next ad the Snow Performance methanol injection kit.

The combination of these two kits is a must have, offering a place to tap in through the BOV for better disbursement of the injection. The pressurized mixture blasts your intake manifold with cooler air and increased octane levels.

Snow Performance is now a supplier of BMW AG & the M4 GTS.
