GY6 Air Performance Upgrade - Level 2
Upgrading to a 30mm intake manifold and carburetor significantly increases the amount of air and fuel provided to your system, feeding your engine's thirst for more power! We highly recommend combining this kit with a performance UNI air filter, Endrigo cylinder head, and exhaust for best results.
This kit eliminates the problem of not having enough room to attach a 30mm carburetor to your vehicle. 30mm aluminum intakes change the angle of the carburetor so that the air intake side points directly at the stock air box mounting bar, preventing the installation of any air filter. The BPNW exclusive intake riser lifts the carburetor up approximately 2.75" giving you plenty of clearance above the crossbar that is common on many GY6 vehicles!
This kit comes with our exclusive intake riser for GY6 150cc engines, 30mm aluminum intake manifold, 30mm pumper carburetor, intake gasket, two o-rings, and socket head mounting bolts for the riser and intake manifold!
You may need to rejet the carburetor with this modification, depending on your buggy's air intake and exhaust setup.
What size jet you need to upgrade to will depend on your elevation and the season (outside temperature) that you will be riding in.
Generally speaking, with just a UNI filter upgrade, you'll need a main jet screw somewhere between 125 and 140. If upgrading the air intake and exhaust, you'll need between 130 and 145 and possibly larger depending on your carburetor, exhaust, and riding location. Purchasing multiple jet sizes can save you a lot of time in the long run. This 30mm carburetor typically comes with a 130 main jet a 39 pilot jet installed (actual factory installed jets may vary at the whim of the factory. We do not open or inspect the jets on these carbs prior to shipment). Feel free to contact Buggy Parts NW if you have questions.
The 30mm carburetors use the 2" opening UNI filter. For easy fitment when using with our 30 or 32mm pumper carburetors, remove the black cap over the choke assembly, install and clamp down this intake elbow or UNI filter, then replace the black cap onto the choke.

This carburetor can be used with your existing throttle cable with no modification!
It is highly recommended to use our high performance Endrigo cylinder head for optimal performance from this modification!
