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)
Precision-Engineered for the BMW 135i
The KAC Intercooler is designed specifically for the 2008–2013 BMW 135i models equipped with the N54 and N55 turbo engines. It’s a direct-fit upgrade, meaning installation requires no cutting or modification to the factory bumper or piping.
Each intercooler features a high-flow bar-and-plate aluminum core, offering up to 80% more cooling volume compared to the stock unit. The result is drastically reduced intake air temps and improved resistance to heat soak — even during repeated high-boost pulls.
Key Performance Benefits
When you install the KAC Intercooler on your BMW 135i, you can expect noticeable, real-world performance improvements:
-
❄️ Reduced Intake Air Temperatures: Keeps boost cool and dense for consistent power delivery.
-
⚙️ Improved Turbo Efficiency: Reduces strain on the turbocharger, promoting longer life and better response.
-
💨 Lower Pressure Drop: Maintains boost pressure across the core for smoother, faster throttle response.
-
🔥 Eliminates Heat Soak: Perfect for track use, spirited driving, or tuned applications.
-
🧊 Supports Higher Boost Levels: Ideal for cars with performance tunes, upgraded downpipes, or larger turbos.
Built Tough — High-Quality Aluminum Construction
The KAC 135i Intercooler is constructed using TIG-welded aluminum for maximum durability and thermal efficiency. The bar-and-plate core design provides excellent heat transfer while maintaining strength under high boost pressures.
This intercooler is engineered to handle 30+ PSI of boost pressure and withstand the rigors of both daily driving and performance tuning. Its corrosion-resistant finish ensures long-term reliability and OEM-like fitment behind the factory bumper.
Direct Bolt-On Installation
Installation is simple — the KAC Intercooler is designed as a bolt-on upgrade for the BMW 135i. It mounts using the factory locations and connects seamlessly with OEM or aftermarket charge pipes.
No trimming, no cutting, and no permanent modifications are required, making it the ideal DIY-friendly upgrade that delivers instant results.
Compatible with:
-
BMW 135i (2008–2013) N54 & N55 Engines
-
BMW 1M Coupe (2011)
-
Compatible with both stock and tuned setups
Perfect for Tuned and Modified 135i Builds
The KAC Intercooler shines brightest when paired with ECU tunes, upgraded intakes, and downpipes. It provides the cooling efficiency required to sustain higher power levels safely.
For stock setups, you’ll enjoy more consistent performance and improved reliability under load. For tuned cars, you’ll unlock your turbo’s full potential while protecting the engine from excessive heat.
Tested and Proven Cooling Performance
Dyno and road testing show that the KAC Intercooler reduces intake air temperatures by as much as 50°F (10–15°C) compared to the factory unit. This ensures stable power output even during long pulls, track days, or high ambient temperatures.
By maintaining cooler, denser air, your BMW produces more consistent horsepower, better throttle response, and stronger midrange torque — all while keeping engine components safe from heat stress.
