Like most turbocharged engines, adding more power generates a lot more heat. Luckily for F9X owners, CSF is here to help keep intake air temperatures (IAT) low. CSF used CFD analysis and testing to create the largest intercooler that goes directly into the OEM cooler. The custom Liquid-to-Air Intercooler cells are 100% larger than the ones on the OEM coolers. The one-piece construction integrates the charge pipe, creating the strongest system possible.
Benefits of CSF coolers:
- Custom CSF core (CFD analysis and testing performed to ensure optimal performance)
- 100% increase in cell volume per cooler compared to OEM coolers
- 1-piece seamless air intake end tanks with integrated charge pipes
- Integrated E85/methanol injection ports (two 1/8 NPT ports per cooler)
- Includes OEM-style "Quick Connect" water connections and sensor ports
- Designed with 3D scanning/Rapid Prototype technology to ensure precise fit and maximum surface area utilization
- "Drop-In Fit" installation
- Significantly lowers intake air temperatures (IAT), improving 60-130 MPH times by approximately 0.30 seconds
- Lifetime warranty
