CSF B58 Thermal Rejection Competition Spacer (For Super Manifold 8200)

The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold (CSF #8200). 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.This Part Fits: Year Make Model Submodel 2020-2023 BMW 540i Base 2020-2023 BMW 540i xDrive Base 2018-2022 BMW 740i Base 2018-2022 BMW 740i xDrive Base 2020-2022 BMW 745e xDrive Base 2020-2024 BMW 840i Base 2020-2024 BMW 840i Gran Coupe Base 2020-2024 BMW 840i xDrive Base 2020-2024 BMW 840i xDrive Gran Coupe Base 2023-2024 BMW M240i Base 2022
