Wagner Tuning 2003+ BMW 3-Series E46 318d/320d/330d Competition Intercooler Kit

This kit includes the Wagner Tuning Competition Intercooler, along with all the necessary mounting hardware and piping to install it on your 2003 and later BMW 3-Series E46 models equipped with the 318d, 320d, or 330d diesel engines. This intercooler is designed to replace the factory unit, offering a significant upgrade for vehicles that have had their engine performance modified or are looking to handle increased boost pressure more effectively.

The core of this intercooler features a high-performance, bar-and-plate design with a generous surface area and depth. This construction allows for much more efficient cooling of the compressed intake air compared to the stock intercooler. Cooler intake air is denser, which means more oxygen can be packed into the cylinders. This improved air density can lead to a noticeable increase in power and torque, especially in modified diesel engines where boost levels are often raised. The kit also includes custom-fit aluminum piping and all the brackets and fasteners needed for a direct bolt-on installation, meaning no cutting or welding is required. Wagner Tuning is known for its well-built cooling components, and this competition-grade intercooler is built to withstand the demands of performance diesel applications.

When installing this intercooler, it's important to ensure all connections are secure to prevent any boost leaks. Because this is a performance upgrade, it's recommended to monitor your engine's parameters after installation to confirm optimal operation. Please note that this intercooler kit is not CARB approved and cannot be shipped to California.
