• Durable Construction: Features high-quality, stainless steel braided lines for superior strength and resistance to wear.
• Enhanced Performance: Designed to ensure optimal performance and reliability of your water-methanol system when relocated.
• Easy Installation: Provides all necessary components for a straightforward trunk mount installation.
• Versatile Application: Suitable for moving standard and custom water-methanol tanks to the trunk of any vehicle.

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.

Regardless of power goals, your B58 needs to breathe! The stock plastic charge pipe fitted between the turbocharger and the intake manifold is adequate for daily driving, but your BMW was built for more than just the daily commute and hauling groceries. If you want to get the most performance out of your BMW, it's time to ditch the restrictive plastic charge pipe and upgrade to Mishimoto's performance aluminum charge pipe.

This Mishimoto performance aluminum charge pipe replaces your stock fragile plastic charge pipe with a free-flowing, 3" aluminum version that's guaranteed to last the lifetime of your vehicle. This design removes the kinks and pinched sections of the stock pipe in favor of smooth-flowing curves. The couplers and flanges transition seamlessly from one component to the next. All of this adds up to a charge pipe that outflows stock by up to 42%!

The Mishimoto performance charge pipe is constructed from two mandrel-bent aluminum pipes with CNC-machined flanges for ease of installation, maximized durability, and perfect fitment. Two pre-installed bungs can be drilled and tapped for boost pressure sensors or methanol injection. The included coupler is made from five layers of silicone with embedded heat-resistant fibers and is reinforced with steel wire to prevent ballooning under high boost pressures. This charge pipe kit is a direct fit with no other modifications required and includes constant-tension worm gear clamps for reliable performance.

Features & Benefits:

Direct fit for 2019+ G20 M340i and G29 Z4 M40i 3-in mandrel-bent piping with internal transitions for reduced turbulence and improved flow The included coupler is constructed with steel wire reinforcement to prevent ballooning under high boost pressures Two-piece design for a perfect fit and easy installation Reduces restriction by up to 42 percent over stock pipe Precision CNC-machined adapters for smooth flow and secure fit Two pre-installed bungs can be drilled and tapped for boost sensors, nitrous, or methanol injection Includes constant-tension worm gear clamps for reliable performance Red powdercoated finish
