Airflow efficiency and maximizing the potential of the stock intake design were the keys to development for the Dinan N55 intake. Dinan improves on the factory air box system by delivering more cool, dense air. The increased amount of air feeds into dual larger volume airbox complete with a larger cone filter that elicit a slightly more audible and sporty tone over its stock counterpart. Dinan claims 10hp and 15ft-lb torque gain with this kit.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This intake is worth 3 points toward your Dinan badge.

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. 

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.

Amplify your driving experience with heightened turbo/induction sound, along with increased air flow, throttle response, and overall performance.

Discover a whole new driving experience, complete with captivating induction sounds, heightened throttle response, and noises you have not yet heard from your turbo. Unleash the full potential of your turbo and engine by ditching the restrictive enclosed intake box. The factory intake is no match for your N55 paired with the Luft-Technik Intak Intake.

It is important to highlight the distinctive dual-cone filter design, featuring a standard conical shape with a smaller inverted cone in the center. This configuration produces an exhilarating sound when lifting off the throttle. The airflow pattern as air exits the filter creates a unique turbo flutter sound, adding to the excitement of the driving experience.

The stock intake box, often labeled as a muffler/silencer, is engineered to dampen induction noise for a more refined ride. However, as enthusiasts, we crave the exhilarating sound of our induction as we accelerate. Our ECS intake is tailored for enthusiasts who seek a heightened driving experience. Crafted with function in mind, it features a silicone coupler, rotomolded inlet tube, heat shield, and filter, seamlessly integrating with the OE fresh air scoop and utilizing stock mounting locations. Experience enhanced performance and a renewed passion for driving with the ECS Luft-Technik Intake for your N55.
