Gas Flowed Manifold

This a standard inlet manifold taken and machined out and then hand finished to port match the head and the gasket goes in between them and give an increased and smoother flow in and out of it that along with opening out the inlet port that connects it to the inlet charge pipe meaning the inlet port has a 28% increase in cross-sectional area and each outlet port to the head has massive 41% increase in cross-sectional area.


This should either help more air get into the engine and reduce already present smoke levels or allow and already mapped/tuned engine running clean to be able to have its fuelling levels increased and thus improve its power and torque produced even further.



To do this costs £75 inc return postage to you and is on an exchange basis only of you sending DonnyDiesel your standard manifold once the ported item has been fitted.
