BMW Gen 1 B58 Charge Air Cooler Manifold - Raw Billet

Thermal Rejection Competition Spacer: Made from KIYLEX?, a patented revolutionary high-performance final stage polymer. KIYLEX? is as strong as aluminum and can withstand temperatures up to 1100?F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier reduces manifold temperatures which helps lower Intake Air Temperatures (IATs), improve charge air cooler efficiency, and combats heat soak. CSF is the exclusive distributor for the KIYLEX? Intake Manifold Spacer for the B58 Motor. Utilizes a High Performance, Motorsports-Grade Bar/Plate Air-to-Water Intercooler Core - Double the Capacity of the OEM Core (12 Rows of Water Cooling vs. OEM 6 Rows) Individual 1/8" NPT Breather Ports for Both Inlet/Outlet Water Connections on Back of Manifold for Easy Air-Bleeding of the System Included KIYLEX Thermal Rejection Manifold Spacer - Proven to lower intake manifold temperatures by up to 15% Plug-and-Play design, R
