HF-Series intercooler for BMW 135i, 335i, Z4 35i (N54/N55)

HF-Series upgrade intercooler for BMW

More power. Lower intake air temperatures. Maximum performance even under extreme conditions.

When intake air temperatures rise, every turbocharged engine noticeably loses power. This is exactly where the HF-Series upgrade intercooler for BMW comes in. Its significantly larger high-performance core and flow-optimised design cool the charge air far more efficiently than the standard intercooler. The result is greater power stability, improved throttle response and noticeably more consistent performance – even at high ambient temperatures or on tuned vehicles.

Developed for maximum efficiency

The HF-Series intercooler was developed with a clear objective: to maximise airflow while minimising pressure loss. The high-quality Bar’n’Plate high-performance core offers:

• excellent cooling performance
• high thermal resistance
• an extremely robust construction
• lower heat soak than many comparable cores

The complete charge-air path was also perfectly matched for flow and efficiency using:

• CAD flow analyses
• 3D scans
• test-bench testing
• measurements on real vehicles

The flow-optimised intercooler tanks made from high-strength cast aluminium ensure even air distribution without unnecessary turbulence.

Noticeable benefits in everyday driving and under load

With the HF-Series upgrade intercooler, your BMW benefits from:

• significantly lower intake air temperatures
• improved throttle response
• greater power stability
• reduced pressure loss
• reduced thermal load on the turbocharger
• optimised airflow
• higher efficiency on tuned vehicles

Particularly in warm ambient conditions or during repeated acceleration, the intercooler effectively prevents power loss caused by excessive intake air temperatures.

Technical details

• Width: 525 mm
• Height: 145.4 mm
• Depth: 120 mm
• Volume without tanks: 10.14 litres
• Standard volume: 7.076 litres
• Core type: Bar’n’Plate
• Surface: black powder-coated

Road use: The intercooler is supplied with a parts certificate in accordance with §19.3 and can therefore be registered for road use.

What does an upgrade intercooler really provide?

A high-performance intercooler does not only offer possible power gains – above all, it helps the vehicle maintain its available power over a longer period. Cooler, denser air improves:

• combustion efficiency
• power stability
• the engine’s thermal resilience

Depending on the setup, power increases of up to 5–10% are possible. It is particularly important that the engine reaches its thermal protection limits significantly later – ideal for performance-tuned vehicles and spirited driving.

Recommendation for maximum performance

For the best result, we recommend combining it with:

• software optimisation
• an upgraded intake system
• a flow-optimised exhaust system

This allows the full potential of the turbocharged engine to be used efficiently.
