CSF Cooling - Racing & High Performance Division A90 Supra / BMW B58 Thermal Rejection Competition Charge-Air Manifold Spacer N/A
$299.00
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.The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold (CSF #8200). Made from KIYLEX, This thermal barrier reduces manifold temps lowering IATs, improves efficiency, and combats heat soak.

CSF Radiator

Anyone who needs a new radiator should consider buying a CSF radiator. A CSF radiator and CSF cooling system offers the best performance for driving and racing enthusiasts. If you have a faulty radiator or are looking to upgrade to a high-performance radiator, a CSF radiator will get the job done. 

What is a CSF Radiator?

During the last 40 years, CSF has manufactured over 10,000 different models of radiators, oil coolers, heat exchangers and condensers for Automotive, Truck, Industrial and Marine applications. Today, their products are sold in over 60 countries throughout the world. Their US Aftermarket Division stocks over 1000 models that cover over 2100 applications for all popular Import vehicles.

CSF supplies radiators and condensers that are designed to meet or exceed original equipment (OE) engineering specifications. Their plants meet ISO 9000 standards and provide parts to OE manufacturers, and to top it all off - check out their industry leading warranty. Simply put, you cannot buy, sell, install or own a better value radiator or condenser.

Why Should I Buy a CSF Radiator

A CSF radiator offers a number of benefits over the competition. Below, we explain the main reasons why you should buy a CSF radiator.

A Market Leader for over 45 Years

CSF has been a market leader for over 45 years, as the company was initially established in 1975 and have been selling CSF radiators ever since. Over time, a CSF radiator has become known for its innovative design and impeccable quality.

High-Quality Radiator Testing

Every single CSF radiator and CSF cooling system has been put through a rigorous series of tests to make sure every system is reliable and performs at a high level. In their testing lab, CSF puts in the time to make sure every product works perfectly. 

Cutting-Edge Technology

Each CSF radiator uses cutting-edge technology to bring customers the best CSF full cooling system possible. CSF racing radiators combine a high-efficiency core, advanced endtank designs, and innovative design and engineering to give our customers the most advanced and efficient radiator possible.  

Get a CSF Radiator or CSF Cooling System From Vivid Racing 

Vivid Racing carries a wide selection of CSF radiator products, including CSF cooling systems and other accessories. If you are interested in learning more or would like to purchase a CSF radiator, please contact Vivid Racing today by calling (480) 966-3040.

CSF takes pride in the quality of its products and offers one of the best warranty’s in the industry. Please refer to the CSF warranty card in the shipping carton for details.

CSF warranty is applicable only to the original owner of the vehicle. Original paper work verifying the proof of purchase and pre-installation cooling system checklist signed by the professional installer is required to process warranty claims.

All warranty claims should be directed to the point of purchase. Due to CSF’s established agreements with Authorized CSF Warehouse Distributors, CSF is unable to handle and/or process warranty related calls/inquires from any individuals – all inquires/warranty related claims should be directed to the point of purchase or an authorized warehouse distributor.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.

Any repairs or alterations to the unit will automatically void the warranty.

Any form of abuse, including the use of improper coolant mixtures, damage caused by steam, corrosion etc and use on commercial vehicles voids the warranty. It is the vehicle owners’ responsibility to maintain the cooling system as specified in the owners manual.
