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

Views: 1
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.The addition of the Thermal Rejection Spacer is especially useful for Drag/Roll-Racing Events where vehicles typically sit in staging lanes in-between racing. This causes extreme heat soak to the liquid-to-air manifold as there is not sufficient airflow passing over the front mount heat exchanger when the car is idling (which is responsible for cooling the charge air fluid that runs through the manifold). This causes the starting IATs on subsequent runs to be higher than on the initial run.The B58 Super Manifold is made from Billet Aluminum and 100% Tig Welded for strength, which allows it to be able to withstand higher boost pressures compared to the OEM plastic manifold. Aluminum has higher thermal conductivity than plastic resulting in a higher rate of heat transfer between the cylinder head and manifold. Adding the Thermal Rejection Spacer reduces heat transfer between the two metal components (cylinder head & manifold). The spacer absorbs the heat from the cylinder head and dissipates it rather than transferring it to the manifold.The Thermal Rejection Competition Spacer was designed for vehicles competing in motorsports who demand the absolute best cooling in order to gain a competitive edge. With that being said, there are significant advantages to adding this spacer upgrade to any vehicle with the CSF B58 Super Manifold installed.Installation InstructionsThis Part Fits: Year Make Model Submodel 2020-2022 BMW 540i Base 2021-2022 BMW 540i xDrive Base 2020-2023 BMW 840i Base 2020-2023 BMW 840i Gran Coupe Base 2020-2023 BMW 840i xDrive Base 2020-2023 BMW 840i xDrive Gran Coupe Base 2023 BMW M240i Base 2022-2023 BMW M240i xDrive Base 2020-2021 BMW M340i Base 2020-2022 BMW M340i xDrive Base 2022-2023 BMW M440i xDrive Base 2020-2022 BMW X3 M40i 2020-2022 BMW X4 M40i 2020-2022 BMW X5 sDrive40i 2019-2022 BMW X5 xDrive40i 2021-2022 BMW X5 xDrive45e 2020-2021 BMW X6 sDrive40i 2020-2022 BMW X6 xDrive40i 2019-2023 BMW X7 xDrive40i 2020 BMW Z4 M40i First Edition 2020-2021 BMW Z4 sDrive M40i 2022 Toyota GR Supra A91 Edition 2020,2022 Toyota GR Supra Base 2020 Toyota GR Supra Launch Edition 2020,2022 Toyota GR Supra Premium
