After extensive and exhaustive dyno testing, Brock’s Performance is proud to introduce the all-new Honda Grom Velocity Stack. This black anodized, billet aluminum velocity stack helps direct air into the intake tract with minimum interference. The intake is especially important to consider when upgrading to a performance exhaust like the Alien Head 2 or ShortMeg 2. The velocity stack fits snuggly inside of the air intake snorkel within your airbox and provides better throttle response and increased power over OEM. Proudly made in the USA and laser etched with the Brock’s Performance logo.

    My mate has the stacks in his 2017 grom with a racing filter and a comp works exhaust. his bike beats mine in 1st and 2nd in a race by about 5- 6 meters (15 - 18 feet). Also 2nd race was around a corner - me on the inside with a stock grom and he still got me by 3 4 - meters by the end of 2nd gear.
