Product Details

Race-Proven Thermal Management: Rein CTA0079

Component: Thermostat Housing Assembly (OE #11537644811)

In professional racing, thermal consistency isn't just about reliability—it’s about performance. When your engine operates at its precise "goldilocks" temperature, you maximize combustion efficiency and protect the tolerances of high-performance internals. The Rein CTA0079 is engineered for teams and drivers who demand that level of OE-plus precision.

This is a complete thermostat housing assembly designed for modern, high-output European engines (including BMW B46/B48 platforms). It is built to ensure that even under the stress of spirited driving or track-day heat cycles, your cooling system remains stable and predictable.

Technical Specifications & Race-Day Advantages:

• Precision Calibration: Every CTA0079 unit is temperature-calibrated to ensure a consistent, lightning-fast response to thermal changes. This prevents the "temperature creep" that can trigger ECU power-cutting or limp-mode during high-load scenarios.

• Zero-Modification Fitment: In the pits, every second counts. This assembly is a direct-fit replacement that matches the original equipment geometry exactly—from the mounting points to the thermoplastic quick-connect fittings.

• Advanced Durability: Manufactured with premium-grade metals and high-resistance polymers, this housing is built to withstand the "war zone" of the engine bay—resistant to extreme heat cycles, road debris, and chemical contaminants.

• Sealing Integrity: To eliminate the risk of catastrophic pressure loss, the CTA0079 comes complete with factory-grade seals. It’s designed to prevent leaks and "comebacks" by replacing the high-failure O-ring and connector points entirely.

• Equalized Flow: Engineered for optimal coolant velocity, ensuring that heat is pulled away from the cylinder head as efficiently as the manufacturer intended.
