Intake Tube 42-48mm for Carbs 21mm-32mm PWK, OKO, CVK, Dellorto

Best air intake ised with velocity stack for 22mm carbs from Dellorto.

Large Intake Tube 90 degree for both PWK carbs and large CVK carbs 30mm - 32mm

The large PWK carbs when installing into a Zuma or other two stroke scooter there is simply not very much room, this help get air filter point down

EMGO and K&N air filter will fit plus UNI Filters, a clamp is needed or the cone type will screw on, this is a mod used in the shop and will need you to understand how it install and how it will help you and it is NOT simply bolt on plus you need to choose an air filter and of course help is here if needed.

Will install in tight spaces. A velocity stack is needed to complete upgrade.
