Detailed Description

URO 93020738601 is an engine crankcase breather hose built for the emission control and crankcase ventilation system on the Porsche 911. The molded NBR construction is selected to handle exposure to heat and oil vapor, helping reduce cracking and splitting that can occur with aged factory hoses. This hose routes from the engine to the oil reservoir on 1984-1989 Porsche 911 applications and is intended to restore proper breather operation when the original hose has failed. If you are replacing a cracked or leaking Porsche 911 crankcase breather hose, 93020738601 provides the correct fitment and hose configuration for the listed vehicles.

This part cross-references 106 43055 066 and URO-011406 for the same application.

What It Helps Fix

• Cracked or split crankcase breather hose
• Oil vapor leaks at the breather connection
• Loss of crankcase ventilation flow
• Improper hydrocarbon emissions control
• Hose deterioration from engine heat exposure

Installation Notes and Tips

Fits 1984-1989 Porsche 911, from engine to oil reservoir. Confirm the hose routing and connector orientation before installation, and inspect adjacent ventilation components for wear, oil saturation, or hardening. Replace any damaged mating connections to help maintain a secure seal and proper crankcase ventilation performance.

Quality Assurance

URO backs this hose with a 24-month unlimited mileage warranty. The molded NBR material and OE-style fitment support consistent replacement of the original crankcase breather hose on Porsche 911 applications.
