D Shape Plenum Material
RMR - 072

The D shape plenum material is extruded from 6063 aluminum. This plenum material is designed with forced induction in mind. Large 4.5" ID offers maximum plenum volume for turbo or supercharged applications. The unique D shape makes it easy for one off fabrication of a manifold while still keeping the performance to a maximum. Quarter inch wall thickness insures strength compared to hand building a sheet metal intake. When ordering set the quantity field to the amount of feet you would like to purchase.
