Product Details

Common Problems This Hose Can Address

• Hose wear from heat and engine bay exposure

Installation Notes and Tips

Verify hose routing, end style, and dimensions before installation. The EMH048 uses a push-in end and OE-exact sizing, so it should be installed in the original location with the factory routing preserved. Inspect nearby fittings and related ventilation components for wear, contamination, or damage before completing the repair.
