The manifold is fully made from the highest grade billet aluminum. Each part is CNC machined with the highest precision and TIG welded to form a single air-to-water charge-air-cooler that is integrated into the intake manifold. The CSF manifold is not only capable of achieving the highest levels of performance of the S58 engine, but it’s all metal design is capable of withstanding extreme boost levels.

The ultra high performance liquid-to-air core is made by PWR. This Bar & Plate core is pressure tested to 120 psi to ensure it will withstand the high boost levels motorsports race teams can throw at it. Feedback from the community has shown the OEM core which is crimped onto plastic end tanks is prone to failure starting at just 27 pounds (psi) of boost pressure.

The G8X M3/M4 S58 “Level-Up” Manifold features a top feed port injection system. The injector bungs are machined directly into the intake runners. The kit includes both the Fuel Rail and CNC Machined Block-Off Caps for non-use.


Faster recovery of Intake Air Temperatures (IATs)

30°F reduction of Intake Air Temperatures (IATs) compared to OEM

Less pressure drop compared to OEM core

Puts less stress on the turbo system, allowing more boost to be made at higher target power levels

Ultra strong CNC Billet construction replaces weak plastic tanks with crimped-on gasket sealing core.

High performance bar/plate intercooler core by PWR pressure tested to 120psi

Top feed port injection w/ included fuel rail (w/ CNC machined block-off caps included for non-use)

Individual ports for each runner for maximum control

Integrated vacuum and parameter pad to measure additional parameters

Easy access to spin-off oil filter

Integrated breather port for easy bleeding of air from the water side of the manifold

Included KIYLEX Thermal Rejection Manifold Spacer

Acts as a thermal barrier that dissipates heat between the cylinder head and intake manifold

Proven to lower intake manifold temperatures by up to 15%

Lowers Intake Air Temps (IATs)

All necessary brackets, hardware, and instructions to install

True Plug-and-Play “Drop-in Fit” Installation – Requires Absolutely No Modifications.
