When you start leaning on the S58 the way it begs to be pushed, the factory plastic manifold becomes the weak link. More boost. More heat. More risk. The CSF S58 Level Up Charge Air Cooler Manifold in Custom Finish changes the whole experience. Throttle response feels sharper. Power carries harder through the top end. Intake temps stay stable when you are deep into a pull or sitting in staging lanes waiting for your next run. This is the upgrade that lets you confidently turn the boost up and actually use it.

This manifold was developed over more than a year of CFD modeling, dyno validation, and real world torture testing. Independent dyno sessions at over 40 PSI showed measurable gains from 4500 RPM to redline. Post intercooler temps dropped significantly compared to OEM, with improved efficiency and minimal pressure drop. Eight back to back dyno pulls under high boost showed controlled heat soak and consistent performance. It is not just stronger. It is proven.

Precision Engineered Design

At the core is a custom PWR bar and plate air to water intercooler core with 23.6 percent more volume than stock. Core size measures 152mm x 239mm x 110mm compared to the OEM 142mm x 230mm x 99mm.

Air side fin height measures 2.43mm with 28 fins per inch. Water side fin height measures 2.00mm with 26 fins per inch using a lance off turbulator design to increase surface contact.

Air and water side fin thickness is just 0.08mm, roughly half the thickness of a conventional bar and plate core. Cladding sheets measure 0.3mm thick and require extremely precise TIG welding.

The core is pressure tested to 120 PSI. Each unit is leak tested under water at 80 PSI for five continuous minutes before final inspection.

The manifold itself is CNC machined from billet aluminum and fully TIG welded into a solid one piece design. No gasketed plenum joints. No crimped plastic tanks. The welded construction increases plenum volume and eliminates common OEM failure points.

Integrated features include port injection fuel rail, individual 1 8 inch NPT nitrous or methanol ports on each runner, dual 10 ORB fittings, three port sensor pad, bleeder screw, machined coolant quick connects, oil filter access recess, and full OEM style mounting provisions.

Includes the KIYLEX Thermal Rejection Competition Spacer, rated to withstand temperatures up to 1100 degrees Fahrenheit. Unlike basic phenolic spacers, KIYLEX dissipates heat rather than trapping it, helping reduce manifold heat soak and stabilize intake air temperatures.

Replaces OEM part numbers 17518092584 and 17518053321.

Configuration Options

Raw billet aluminum manifold.

Thermal Dispersion Black finish for improved surface heat transfer.

Custom powder coat finishes available in gloss, satin, or textured options.

DLC coating available for maximum durability and a unique high end finish.

Integrated port injection with included fuel rail and block off bungs if not used.

Integrated nitrous or methanol ports with steel bungs included.

Exhaust Tips & Customization

Not applicable. This product is focused on intake charge cooling and manifold performance.

Custom finish options include Thermal Dispersion coatings in black or grey, full color matched powder coating, or DLC coating for maximum durability and visual impact.

Production & Lead Time

Each manifold is built in limited production and hand assembled in the USA. The core construction and precision TIG welding require skilled technicians and strict quality control. Typical lead time is three to four weeks depending on finish selection. Quality and leak testing always come first.
