Customers looking to add a N54 Manifold can expect a higher peak in horsepower while sacrificing some low end torque in comparison to the stage 3 intake manifold*.

Recommended for manual transmissions (OR 325i or 330i automatics) as this allows you to gain some more peak power by tuning the redline to 7500rpm while the 328 automatic transmission will be limited to 7000rpm

For a N52 turbocharged or supercharged build, it is highly recommended for the N54 manifold for its design for boost and for the reliability of less moving parts (I.e. DISA valves)
