 |
|
Click to enlarge image(s) |
Put some life into your Honda GX340, GX390 engine by adding our billet aluminum custom fabricated intake manifold! Our manifold is a direct bolt on part that doesn't require any other fabrication to make it fit. Our intake includes the intake bolts, intake gasket and pulse fitting. If you do not need the pulse fitting just plug it with an 1/8"npt plug. Either way it is there for you so there is NO drilling necessary to add this feature. Don't forget to add our Mikuni 32mm racing carburetor in either a round slide or flat slide version. The throttle response and power increase is awesome!
