Cold Air Intake Tube (GY6)

Cold Air Intake Tube for GY6 Scooters

This intake tube is built for 125cc and 150cc GY6 scooters and is meant to help engine output. It is made to work with larger carburetors, covering sizes from 24mm to 40mm from makers such as Mikuni, Keihin, and Dellorto. As part of our GY6 scooter range, it can help raise horsepower and quickening, and may also contribute to better fuel economy.

What You Gain

With this tube, cooler and denser air reaches the engine, which can translate into more power. You should notice quicker pull off the line, which helps when pulling away from traffic lights. The part also gives the engine a sharper exhaust-style intake note, adding to the ride.

Fit and Compatibility

This tube works with engines built on the 157QMJ base, spanning a broad set of models. It suits several engine codes, so it fits many GY6 scooters. It is a good choice for riders who run a larger carburetor and want to get the most from that setup.
