Double the capacity of the stock charged air cooler
Bar & Plate design
Lower pressure drop compared to factory
Integrated sensor pad with 3 x 1/8" NPT ports
1/8" NPT ports on each cylinder runner for nitrous or methanol injection
No modifications for install - accepts all factory connections and even beauty cover
Thermal Rejection spacer adapter - reduces heat transfer from the head to the manifold
The B58A engine needs this intake charge cooler if you're getting into serious tuning or track use.
The factory cooler is adequate for the expected usage of the car - regular street driving with the occasional full throttle runs. But remember that the engine computer is constantly evaluating and adjusting boost and torque output based on intake air temperature. Repeated hard use, especially in a track environment, will overwhelm the stock cooling system and lead to heat soak. Higher intake air temperatures will force the ECU to dial back timing and boost, dropping power output or causing limp mode.
The solution is a larger cooler but the B58 layout doesn't allow for a simple swap - the cooler is part of the intake manifold. CSF partnered with several well-known intake specialists to develop a new intake manifold with a cooler that has more surface area, capacity, and less pressure drop. More heat management means the cooler will keep intake air temps lower and for a longer time. It will also recover more quickly when heat saturated. The new top-mount cooler is still water cooled using all of the original connections but it can now handle more heat before the ECU steps in.
This is a direct replacement for the stock charge air cooler but also includes some additional features aimed at racers and tuners - external fuel rail, 1/8" NPT ports for nitrous or methanol, and a sensor pad with 1/8" NPT ports. All of these are optional and can be blocked off when not needed, meaning you can bolt this CSF cooler on for a 1:1 upgrade, experience the power gains and reliability, and then plan the rest of your build.
The CSF manifold is not designed to operate above 60 PSI. Any users who chose to operate their vehicle with the CSF manifold over 60 PSI does so at their own risk. Operation at these pressure levels will void the CSF Limited 2 Year Warranty.
Available as raw aluminum, black, or any other custom color or finish you can think of. Black and color options are a Thermal Heat Dispersion Cerakote that results in a faster dissipation of heat than traditional powdercoat.
