Ported Intake-manifold

[mengz]

just wanna ask if powerzone does porting for the intake-manifold for Waja 1.6???
if yes, how much will it cost?

thanks

We can only do a port matching process here as the internals of the manifold cannot be accessed. Anyway, the internal finish is not affecting performance too much. It's more useful to port the cyl head.
The basic rule is that all parts along the intake path must be checked and corrected (by porting) if they present a bottle-neck. It's no use doing just one area. Hope you get the picture?
