💡 Product Highlights:
🔥 Built for High Performance
Developed for high-boost S58 applications, the CSF manifold is engineered to outperform under extreme power and thermal demands. Tested at 45 PSI on builds making over 1000 WHP, it delivers:
-
Superior thermal efficiency: 89%+ vs. 86% OEM
-
Minimal pressure drop: 1.10 PSI under full load
-
Increased core volume: +23.6% vs. OEM
❄️ Industry-Leading Cooling Technology
Featuring a custom PWR bar-and-plate core with 48 air rows and 49 water rows, this manifold utilizes a counter-flow design to optimize thermal exchange. With higher fin density and thinner materials than any competitor, it outperforms everything else on the market -- including OEM and "German-engineered" alternatives.
🧊 KIYLEX® Thermal Rejection Spacer (Exclusive)
CSF includes its proprietary KIYLEX® thermal barrier spacer, which isolates the manifold from the cylinder head to drastically reduce heat transfer, combat heat soak, and improve charge-air cooling efficiency during extended high-load operation (e.g., roll racing, track driving).
