BMW 335i 135i N54 Doc Race Intake Manifold
Sorry, this item is out of stock
After 2 years of waiting we are proud to present the Doc Race N54 Intake Manifold!
Two major hurdles preventing large numbers in our platform are fueling and the plastic box BMW decided to use for an intake manifold. We wanted to address both with one solution. As fabricators we knew this was an easy fix for us, but what about everyone else? After countless hours of R&D, testing, dyno time and general obsession, we decided on a design and started the ball moving forward to mass production. This was built by and for the true BMW Enthusiasts!

The Original Design and Prototype was tested back to back on the same car against the Factory BMW Intake Manifold. The car tested was a single turbo 6466, stock head and block.
On just 18lbs of Boost we were able to add 23hp and 16ft/lbs of torque peak gains! We expect these to grow much higher as boost is increased and with the right tune. You can run extremely high boost, like over 50psi HIGH!!!
