Ensure optimal engine performance with the replacement of your vacuum system hoses. The vacuum system plays a crucial role in the engine's functionality, transforming it into an efficient pump that influences air-fuel mixture and combustion. Damaged vacuum hoses can lead to various performance issues, from rough idle to difficulties starting the engine. If you're experiencing these issues, it's time to upgrade to this plastic hose with a 2.3mm inner diameter. The hose is black, arrives in an 8-foot section, and can be easily cut to the desired size for a perfect fit.

Key Features:

• Engine Optimization: Replacing old hoses ensures the vacuum system operates at peak performance.
• 2.3mm Inner Diameter: Designed to meet specific engine requirements.
• Black Color: Blends seamlessly with the engine components.
• 8-Foot Section: Provides flexibility to cut the hose to the required length.
• Easy Installation: Upgrade without hassle for improved engine efficiency.

Upgrade your vacuum system with this high-quality plastic hose, addressing performance issues and ensuring your engine runs smoothly.

Maximize cooling efficiency and take your BMW’s performance to the next level with the ECS High Performance Cooling System Bundle—a complete, track-proven upgrade engineered to handle the extreme thermal demands of the G2X B58 platform. Developed by the enthusiasts at ECS Tuning, this system includes both the High Performance Aluminum Radiator and High Performance Aluminum Heat Exchanger, designed to deliver consistent, reliable temperature control in even the most demanding driving conditions.

The factory BMW cooling components just aren’t built for high-performance or track use. Both the OE radiator and heat exchanger feature weak plastic end tanks and undersized single-row cores—common failure points when exposed to elevated heat and pressure. ECS set out to solve these shortcomings with an all-aluminum, dual-row system designed for enthusiasts who demand more from their BMW. ECS engineers started by replacing the fragile plastic end tanks with TIG-welded 6061-T6 aluminum for unmatched durability. Each tank is precision-crafted with CNC-machined billet aluminum hose connections, flanges, and brackets, ensuring direct OE-style fitment with the factory hoses, fan shroud, and accessories—no cutting or modifications required.

Both the radiator and heat exchanger feature high-capacity, dual-row 42mm cores, a massive improvement over the factory’s 34mm and 25mm single-row designs. The result? Faster heat dissipation, lower intake air temperatures, and more consistent performance, whether you’re cruising or carving apexes.

Radiator: Replaces OEM part numbers 17118666740 and 17115A30677

Heat Exchanger: Replaces OEM part numbers 17118666811 and 17115A54040

Features:

6061-T6 aluminum construction eliminates weak plastic end tanks Dual-row core design for increased cooling capacity and efficiency Radiator: 42mm dual-row core (45% thicker than OE 34mm core) Heat Exchanger: 42mm dual-row core (72% thicker than OE 25mm core) TIG-welded end tanks for superior strength and reliability Polished aluminum finish for a premium, high-performance look CNC-machined connectors and brackets for perfect OE fitment Fully compatible with factory hoses, fan shroud, condenser, and intercooler Direct bolt-in installation—no modifications required

BMW’s turbocharged B48 and B58 engines use a water-to-air charge air cooling system, with a front-mounted heat exchanger responsible for heat dissipation. Unfortunately, the factory single-row, 25mm core design is quick to heat soak under high load, leading to excessive intake air temperatures and potential limp mode conditions—especially on modified or track-driven cars.

ECS Tuning’s High Performance Aluminum Heat Exchanger was developed in-house as a direct replacement and upgrade over the factory unit. Designed for durability and maximum cooling efficiency, this heat exchanger is a must-have for high-horsepower street builds, spirited canyon driving, and extended track sessions. Built from TIG-welded 6061-T6 aluminum, the ECS unit eliminates the factory plastic end tanks—one of the system’s most common failure points. Each heat exchanger features CNC-machined billet aluminum hose connections, mounting flanges, and brackets for perfect OE fitment and trouble-free installation.

To drastically improve thermal efficiency, the factory 25mm single-row core has been replaced with a dual-row, 42mm performance core, offering a 72% increase in thickness. This expanded design nearly doubles coolant volume, allowing for greater heat dissipation, reduced intake air temperatures, and more consistent power delivery.
