IMPROVED INTAKE EFFICIENCY: The intercooler improves the engine’s intake efficiency by cooling the hot air compressed by the supercharger, making the air entering the cylinders denser. This directly leads to more complete fuel combustion and stronger power output.
REDUCED ENGINE TEMPERATURES: Intercooler reduces the risk of engine overheating due to hot air, helping to maintain the engine in a safe and efficient operating temperature range, prolonging engine life and minimizing potential thermal damage.
IMPROVED FUEL ECONOMY: Intercooler By improving combustion efficiency, intercoolers help to reduce fuel consumption, which in turn improves vehicle fuel economy and reduces running costs.
ENHANCE STABILITY AND RELIABILITY: Under long time or high load operation, the intercooler can effectively stabilize the intake air temperature to ensure the continuity and stability of the engine output, which is more obvious especially under hill climbing, high speed driving or heavy load conditions.
EASY INSTALLATION: Intercooler is designed with plug-and-play principle in mind, providing clear installation guide and necessary accessories, which makes it easy for users to install on their own or upgrade in specialized stores. (Professional installation is recommended)

Engineered Specifically for BMW 335i (E90 / E92 / E93)

The KAC Intercooler Kit is a direct-fit upgrade for the 2007–2013 BMW 335i, compatible with both N54 twin-turbo and N55 single-turbo engines. It fits seamlessly into the factory intercooler location, requiring no cutting, trimming, or modification to your front bumper or air ducts.

Every KAC intercooler is CNC-machined for precision fitment and built from TIG-welded aluminum, ensuring superior strength and performance under high-boost conditions.

High-Efficiency Bar-and-Plate Design

The KAC Intercooler features a high-density bar-and-plate core, engineered to maximize heat dissipation and minimize pressure drop. Compared to the OEM intercooler, this unit offers:

• ❄️ Up to 80% more core volume

• 💨 Significantly lower intake air temps (drops up to 50°F)

• ⚙️ Reduced restriction for better airflow

• 🔥 Improved turbo spool and throttle response

The result is smoother power delivery, stronger midrange torque, and improved reliability, even under aggressive driving or tuning.

Built Tough for High Boost and Long-Term Reliability

The KAC 335i Intercooler Kit is constructed from 100% TIG-welded aluminum — no plastic end tanks, no weak points. The rugged design ensures consistent cooling and long-term durability, even under sustained boost pressures exceeding 30 PSI.

Its corrosion-resistant finish protects against the elements, while the precision-welded end tanks ensure optimal internal airflow and maximum strength.

Direct Bolt-On Installation

This kit is designed for a plug-and-play installation. It mounts directly in place of the factory intercooler using OEM hardware and connects seamlessly with both stock and aftermarket charge pipes.

Installation typically takes 1–2 hours and can be done in a home garage with standard tools — no fabrication required.

Compatible Models:

• BMW 335i (E90 Sedan, E92 Coupe, E93 Convertible) — N54 / N55 Engines

• BMW 335is (2011–2013)

• Also compatible with select 135i, 1M, and 335xi applications

Ideal for Tuned and Stock 335i Builds

Whether your 335i is bone stock or tuned with a JB4, MHD, or Cobb Accessport, the KAC Intercooler Kit provides the cooling capacity to handle your setup.

For stock cars, it reduces heat soak and provides more consistent power delivery during spirited driving. For tuned or high-boost builds, it’s essential to maintain low IATs and safe operating conditions at higher boost levels.

Performance Gains You Can Feel

Dyno testing and real-world performance show immediate results after upgrading to the KAC Intercooler:

• ⚡ 10–20 HP gains from cooler intake temps

• 🧊 Reduced IATs by up to 50°F (10–15°C)

• 💪 Faster turbo spool and improved midrange pull

• 🔥 Better reliability and consistency under high load

This isn’t just a cosmetic upgrade — it’s a performance enhancer that lets your 335i breathe, spool, and accelerate the way it was meant to.
