CSF BMW Gen 1 B58 Charge-Air-Cooler Manifold - Black

If you're pushing your Gen 1 B58 BMW engine beyond stock, especially with bolt-on modifications, turbo upgrades, or performance tuning, the factory charge-air-cooler manifold can become a bottleneck. This CSF "Super Manifold" is designed to handle the increased demands of modified B58 engines, offering a significant upgrade in cooling efficiency and reliability. It's built to withstand higher boost pressures and combat heat soak, which can cause your engine to pull timing and even enter limp mode.

Crafted from solid billet aluminum and 100% TIG welded, this manifold is much stronger than the stock plastic unit. It features a high-performance bar/plate air-to-water intercooler core with double the capacity of the OEM core, using 12 rows of water cooling compared to the stock 6. To further reduce heat transfer from the cylinder head, it includes a KIYLEX Thermal Rejection Competition Spacer, a patented polymer that acts as a strong thermal barrier. CSF also engineered unique features like an air inlet divider to ensure consistent airflow to all cylinders and a recessed design for easy oil filter access without removing the manifold, complete with a counter-balanced protrusion to maintain smooth airflow. It also comes equipped with top-feed port injection bungs and an included fuel rail for users adding port injection, along with individual ports for nitrous or methanol injection on each runner.

This CSF manifold is a comprehensive solution for Gen 1 B58 owners looking to maximize performance and reliability in their modified BMWs, including models like the 340i, 440i, and M240i. The kit comes with a well-thought-out hardware kit, including brackets, bolts, and fittings, along with detailed diagrams and instructions for installation. It also includes breather ports for easier air bleeding of the water cooling system and an integrated sensor pad with three NPT ports for additional parameter monitoring.
