A TCM B58 Intake Manifold is an essential upgrade for any enthusiast looking to maximize the performance of their B58 engine.

Our Intake Manifold is made from high-quality Aluminum. This unit is CNC'd our of Aluminum instead of the cheap Cast units that you'll see on the market. This leads to a stronger design that will last the test of time. It also makes a stronger unit, to handle increased boost pressures.

This unit's charge cooler  is significantly larger than the factory unit. With a larger core, you get more airflow going through the charge cooler allowing it to cool your air more. With the larger design also brings an increase in coolant volume. More coolant means it can absorb more heat, before it gets hot. Both of these together means you'll get colder air going into your engine and the air will stay cold for longer.

The intake manifold comes with an optional 6 port injection rail. The holes will come pre-drilled and capped if not wanting to be used.

The intake manifold also includes NPT ports for each cylinder for Meth or Nitrous injection.
