Our plenum material is designed to use
with forced induction engines. The extrusion
material makes it easy for one off manifold
fabrication while still keeping the performance
to a maximum. The quarter inch wall thickness
insures the strength that's needed for high
horse power forced induction.
It's much stronger than a hand built sheet
