Intercooler

Maximize performance and reduce intake air temperatures on your E90 335d with the Turner Motorsport Stepped Intercooler. Designed as a direct-fit upgrade for the factory intercooler, this high-efficiency unit increases charge air volume and airflow, helping your diesel-powered BMW run cooler, stronger, and more efficiently.

Cooler air is denser air, and denser air means more power. By reducing intake air temperatures (IATs), this upgraded intercooler allows your M57 engine to pack in more air and fuel per cycle, translating to improved performance across the RPM range.

Engineered for performance and durability, the Turner stepped intercooler features cast aluminum end tanks and a bar-and-plate core design, offering superior thermal efficiency and structural strength. Compared to the stock unit, it delivers a 65% increase in both frontal surface area and internal cross-sectional flow, ensuring better heat dissipation and reduced pressure drop. All of this performance comes in a lightweight package under 20 lbs.

Finished in a stealthy black coating with laser-etched Turner logos, this intercooler not only performs but looks good doing it.

Key Features:

Designed specifically for the E90 335d (M57 engine)
Cast aluminum construction for durability
High-efficiency bar-and-plate core
65% increase in frontal and cross-sectional area
Significantly lowers IATs for improved power and reliability
Reduced pressure drop for more consistent boost delivery
Lightweight design – under 20 lbs
Dimensions: 520mm wide × 200mm tall × 150mm deep
Direct bolt-on installation – no modifications required
If you're looking to get the most out of your E90 335d, the Turner Motorsport Stepped Intercooler is a must-have upgrade for your turbo diesel intake system.

BMWs turbocharged S55 engine uses a water-to-air charge air cooling system, with a front-mounted heat exchanger responsible for heat dissipation. Unfortunately, the factory single-row, 27mm 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.

To solve this issue, we've developed a drop-in upgrade over the factory unit. Engineered 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 5052 aluminum, our design eliminates the factory plastic end tanks one of the systems 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.

By replacing the OEM 27mm single-row core with a robust 35mm dual-row design, this heat exchanger dramatically increases both cooling capacity and surface area. Frontal area jumps from 307mm to 475mm, resulting in a 100% increase in coolant volume and significantly improved heat-soak resistance. The outcome? Lower, more stable charge air temperatures that help your S55 deliver consistent, reliable power on the street or at the track.

Complete Silicone Intake System Kit

This kit includes the intake boot, hot side boot, and cold side elbow kit to complete your MINI's intake system with silicone components. It offers a matching set for your engine bay.

M7 Speed proudly announces the release of its newly developed 100% silicone, four-ply fiber reinforced intake hose for all MINIs equipped with the N14 turbocharged engine. This direct OE replacement part provides superior durability, enhanced airflow, and virtually unlimited service life. Beyond its outstanding performance, it also adds a striking under-hood appearance that MINIs desperately need.

Unlike other similar hoses on the market, the M7 hose retains the OE PCV (positive crankcase ventilation) connection location and size, allowing the OE hose and connector to be installed without any modifications. This ensures no disruption to the PCV electrical connection, eliminating the risk of triggering a DTC code (Check Engine Light). The kit comes complete with three properly sized stainless steel clamps and easy-to-follow installation instructions. Please note that this part is only compatible with MINIs equipped with the N14 turbocharged engine that have one large PCV vent hose connected from the intake hose to the cam cover.

Key Features:

• Constructed from 100% silicone materials, resistant to oil and most chemicals.
• Designed for high-temperature service up to 300°F (149°C).
• Four-ply fiber reinforced construction for maximum strength and durability.
• Retains stock PCV connection location and size for ease of installation.
• No modifications or cutting required for installation.
• Provides 33% larger internal flow volume compared to the stock part.
• Features a super smooth inner flow surface and transitions, promoting better airflow to the turbocharger.
• Available in four standard M7 colors: BLACK, RED, BLUE, and GREEN.
• Dimensions: 2.75” (70mm) ID at the MAF sensor and 1.97” (50mm) ID at the turbo inlet.
• Easy DIY installation.

Heatsoak is one of the obstacles to making big power from turbocharged engines. The stock intercooler design is commendable for single runs at the stock boost levels, but add any more boost and the system is quickly overwhelmed. As the ECU corrects for heat soak, the boost will be decreased and power reduced. Installing an upgraded intercooler is essential to keeping the engine computer from restraining boost as temperatures climb and helps to maintain boost levels even in the face of elevated turbocharger temperatures. The Evolution Racewerks Competition intercooler is much larger than stock, providing more surface area for cooling air to pass through. Even heat soak at low speeds is reduced, making this a worthwhile addition even for stock or mildly tuned engines.

Available in either Brushed, Polished or Type III Hard Anodized Black, this intercooler looks great and holds up! The hard anodized will not only give your car the stealthy look but will also protect the intercooler fins from damage. Without any reduction in thermal efficiency, hard anodizing will prevent your fins from getting deformed as easily from daily driving or road debris. It also has the added benefit of not drawing attention to the fact that the vehicle has been modified. 

The Full Kit consists of everything included in the Standard Kit but adds the Turbo to Intercooler Pipe Kit (TIC Pipe). Increase throttle response, as well as decrease turbo lag, are the benefits of the new TIC Pipe Kit.  With the Full Kit, ALL the factory rubber and plastic intercooler pipes will be replaced.  You will have full hard piping throughout your system.

Based out of Nevada, Evolution Racewerks stays at the forefront of performance BMW technology and offers top quality aftermarket parts ahead of the competition. Proven performance gains and an exhausting attention to detail is making ER one of the top names in the industry. Backed by countless successful and happy customers with the timesheets to prove it, Evolution Racewerks is a name you can count on when adding reliable horsepower.
