About this intake manifold
Combined intake manifold and water-to-air charge cooler upgrade for the F-Series B58.
Frequently asked questions
What is a cast intake manifold and why upgrade?
A cast aluminium manifold replaces the OEM unit with larger runners and a bigger plenum, reducing the intake restriction that limits power on big-turbo B58 builds targeting 500+ bhp.
Which F-Series BMW models does the B58 Gen 1 cast manifold fit?
The B58 Gen 1 cast manifold fits the BMW M140i (F20/F21), M240i (F22/F23), 340i (F30/F31), 440i (F32/F33/F36), and M2 Competition (F87 B58 variant).
What power level justifies a cast manifold?
Recommended for Stage 3+ builds targeting 500+ bhp on the B58 Gen 1. Below this, the OEM manifold is generally not the primary restriction.
Does it require supporting modifications?
Yes. The cast manifold is part of a Stage 3+ package – fit it with an upgraded turbo, catless downpipes, intercooler, and a full custom ECU remap.
