When the old standard was an inefficient cast aluminum manifold, we knew
we could do better. Fast forward and you’ll find the original manifolds
have been converted to door stops, making way for the efficient design
that was born by Pro-werks.
This volumetric efficient smooth radius design outflows cast aluminum
manifolds by 10%. High velocity eliminates fuel puddling resulting in a
cleaner mixture with improved throttle response. Lightweight sheet
aluminum construction features quality TIG welding and Micro-polishing. Optional defrost tube may have warm water or oil circulated through it
to reduce condensation in cool or damp running conditions.
It’s really quite simple: The engine
is an air pump. The more air and fuel you can deliver efficiently the
more horsepower your engine may produce.
There are several combinations available for proper fitment. Restrictive adapters are not required.
These are manifold works of art, beautifully crafted at the Pro-werks facility.Proudly made in the USA.
