Designed for Performance Exhaust Systems

Performance headers and sports mufflers significantly improve exhaust flow, but to extract the maximum benefit the Bosch Motronic ECU requires recalibration. OE Match software has been specifically developed to provide the additional fuel and optimised ignition timing needed for freer-flowing exhaust systems, ensuring safe air-fuel ratios while preventing excessive knock sensor intervention.

The result is a dramatic improvement in the way your 964 drives, including:

• Increased low and mid-range torque
• Sharper throttle response
• Elimination of the factory flat spot below 4,000 rpm
• Smoother idle
• Dyno-proven horsepower gains
• Improved acceleration and everyday drivability

The engine comes alive from low RPM, making the car feel noticeably lighter and more responsive whether you're driving on the road or attacking your next track day or autocross.

Dyno Developed for Real-World Driving

Unlike generic replacement chips, OE Match calibrations are written specifically for each engine and exhaust configuration.

Every program has been extensively developed through hundreds of hours of dyno tuning, road evaluation and real-world testing using everyday pump fuel. Ignition timing, fuel delivery and throttle mapping have all been optimised to deliver:

• Smoother idle
• Increased low and mid-range torque
• Sharper throttle response
• Elimination of the factory sub-4,000 rpm flat spot
• Stronger acceleration throughout the rev range
• Dyno-proven horsepower gains
• Improved everyday drivability

Unlike inferior calibrations, OE Match software maintains safe air-fuel ratios, ensuring the engine continues to run efficiently while avoiding the lean conditions that can reduce performance and increase knock sensor activity.

Includes the Lightweight Flywheel (LWF) Fix

Every OE Match calibration includes the latest Lightweight Flywheel Fix, eliminating the stalling and RPM dip commonly associated with RS lightweight flywheel conversions. The software also improves clutch engagement and throttle response while remaining fully compatible with standard flywheel cars.

Developed Specifically for Your 964

Unlike generic replacement chips, every OE Match calibration has been extensively developed through dyno testing and real-world road evaluation using premium pump fuel. Each program is tailored to your exact engine specification and exhaust configuration, delivering maximum performance without triggering the Check Engine Light.

Suitable for:

• Porsche 964 Carrera 2 & Carrera 4 Manual or Tiptronic transmission

• Porsche 911 1975-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1979 3.0L / SC  

Diagram Ref No 9

Over time, the original hose can become brittle, split, crushed, or deteriorate due to continual exposure to heat, vibration, and age. A damaged heater blower hose can reduce airflow, decrease heating efficiency, and allow heated air to escape before it reaches the passenger compartment. Replacing a worn hose restores the efficiency of the heating system and helps maintain passenger comfort. This OE Match heater blower hose is ideal for routine maintenance, heating system repairs, and Porsche restoration projects.  

What This Product Does:

• Transfers heated air from the blower to the heating system.
• Maintains efficient airflow through the ventilation ducts.
• Supports effective cabin heating and demisting performance.
• Helps minimise heat loss within the heating system.

Symptoms Of Wear Or Failure:

• Reduced airflow from the heater vents.
• Poor cabin heating performance.
• Heated air escaping within the engine compartment.
• Split, cracked, or crushed heater hose.
• Excessive deterioration caused by heat or age.
• Difficulty maintaining cabin temperature.
• Heating system restoration requiring replacement ducting.

Why Replacement Matters:

• The heater blower hose is an essential component of the Porsche heating and ventilation system, carrying warmed air from the blower assembly to the cabin. A damaged or deteriorated hose can reduce airflow, decrease heating efficiency, and allow valuable heated air to escape, resulting in poor cabin comfort and less effective windscreen demisting.
• Replacing a worn heater blower hose restores proper airflow, improves heating performance, and helps ensure the heating and ventilation system operates as intended. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Heater Blower Hose provides the correct fit, dependable performance, and long-lasting durability, making it an excellent choice for Porsche maintenance, repairs, and restoration projects.
