NRF 350204 Air Conditioning Installation

The NRF 350204 is a high‑performance air conditioning condenser designed specifically for the Porsche 911 series, including the 991 and 918 models. It serves as an essential component in the vehicle’s climate control system, ensuring optimal cooling efficiency, reliability, and longevity.

Key Features and Design Excellence

• Easy‑Fit Construction: The condenser is engineered with a modular mounting interface, allowing for straightforward installation without the need for extensive modifications. This feature reduces labor time and simplifies maintenance procedures.
• Aluminum Alloy Core: Constructed from lightweight yet durable aluminum, the core offers superior thermal conductivity while maintaining structural integrity under high pressure conditions.
• Seamless Integration with Porsche Systems: The design aligns perfectly with the Porsche 911’s existing HVAC architecture, ensuring seamless communication between the condenser and the vehicle’s electronic control units (ECUs).
• Enhanced Heat Dissipation: Optimized fin geometry increases surface area, promoting efficient heat transfer from refrigerant to ambient air. This results in lower operating temperatures and improved overall system performance.
• Corrosion‑Resistant Coating: A specialized anti‑corrosion layer protects the condenser against moisture, road salts, and environmental contaminants, extending service life.

Compatibility Matrix

The NRF 350204 is specifically tailored for the following Porsche models:

For each model, the condenser fits without requiring a frame or additional brackets, thanks to its EASY FIT design.

Installation Procedure

1. Preparation: Disconnect the vehicle’s battery and ensure the HVAC system is de‑pressurized. Remove any existing condenser components following manufacturer guidelines.
2. Mounting: Position the NRF 350204 onto the designated mounting points on the rear of the engine bay. Secure with the supplied fasteners, ensuring a tight seal to prevent refrigerant leaks.
3. Electrical Connections: Connect the condenser’s wiring harness to the vehicle’s ECU and power supply. Verify correct polarity and secure all connections with heat‑shrink tubing.
4. Refrigerant Charging: Refill the HVAC system with the specified refrigerant (commonly R134a or R1234yf, depending on model). Use a calibrated gauge set to monitor pressure levels during charging.
5. System Test: Power up the vehicle and activate the climate control. Observe condenser operation, ensuring proper airflow and temperature regulation. Check for any abnormal noises or vibrations.
