Intercooler Hose

• Heat Resistance: Silicone and certain rubber blends can tolerate temperatures up to 400°F (200°C) without degrading.
• Pressure Strength: The braided reinforcement prevents the hose from expanding under pressure, preserving airflow efficiency.
• Chemical Stability: Resistance to oil, fuel, and coolant vapors ensures longevity even in harsh engine bay environments.

Compatibility with BMW E39 Series

The METZGER 2400137 intercooler hose is specifically engineered for the BMW 5 Series (E39), covering both the limousine and touring variants. Its dimensions—length, inner diameter, and connector type—match the OEM specifications, guaranteeing a seamless fit:

• Length: Approximately 1.2 meters (adjustable depending on vehicle configuration).
• Inner Diameter: 22 mm, matching the standard BMW turbocharger intake.
• Connector Type: Flanged or threaded ends that mate directly with the intercooler outlet and throttle body inlet.

Installation Overview

1. Remove Old Hose: Carefully detach the existing hose from both the intercooler and throttle body, noting any retaining clips or bolts.
2. Prepare New Hose: Inspect the METZGER 2400137 for any manufacturing defects. Ensure that the ends are clean and free of debris.
3. Attach to Intercooler: Slide the hose onto the intercooler's outlet flange, secure with the provided clamp or bolt, and tighten to manufacturer specifications.
4. Route to Throttle Body: Guide the hose along the engine bay, avoiding sharp bends that could kink the tube. Use cable ties or hose clamps as needed.
5. Secure at Throttle Body: Connect the other end of the hose to the throttle body inlet, ensuring a snug fit and tightening any fasteners.
6. Check for Leaks: After installation, start the engine and inspect all connections for pressure loss or air leaks.

Performance Benefits

Replacing an old or damaged intercooler hose with a high‑quality METZGER 2400137 can yield noticeable improvements:

• Reduced Air Temperature: A well‑sealed hose prevents hot air from re-entering the intake, maintaining cooler airflow.
• Improved Pressure Retention: The reinforced construction minimizes pressure drop across the hose, allowing the turbocharger to deliver more boost.
• Enhanced Reliability: With superior material resilience, the hose withstands long‑term thermal cycling and mechanical stress.

Maintenance Tips

• Inspect the hose annually for signs of wear such as cracking, bulging, or discoloration.
• Check all clamps and fasteners to ensure they remain tight; loose connections can lead to air leaks.
• Avoid exposing the hose to extreme heat sources (e.g., exhaust manifolds) that could accelerate material degradation.
