URO 2710161321 Spark Plug Tube Seal

Overview

This URO spark plug tube seal is a specific-fit replacement for Mercedes-Benz applications that need a reliable valve cover seal around the spark plug tube. It addresses oil intrusion at the plug well and helps restore proper sealing where hardened or cracked seals can lead to performance issues.

Part number 2710161321 is built with an OE-style profile and compression characteristics for consistent sealing. It is a practical choice for Mercedes-Benz C250 and SLK250 service work where the original seal has aged from heat and oil exposure.

Key Features

• ACM material resists engine heat and oil degradation.
• O-ring seal design supports a tight seal at the valve cover.
• Flat rim shape and OE-style profile promote proper compression.
• Black finish for a clean, factory-style appearance.
• Specific-fit design for targeted engine service applications.

Detailed Description

The URO 2710161321 spark plug tube seal is engineered for valve cover sealing where spark plug wells need protection from oil seepage. Its ACM construction and OE-style durometer help maintain sealing pressure between the valve cover and cylinder head, reducing the chance of oil buildup around the spark plug and ignition wire connector. For Mercedes-Benz C250 and SLK250 service, this seal supports a proper repair when the original component has become brittle, hardened, or cracked.

Part number 2710161321 is also cross-referenced to Elring 428.480 and MAHLE VS50676 for the same application.

What It Helps Fix

• Oil collecting around the spark plug tube.
• Misfire caused by contamination in the plug well.
• Vacuum leaks from a hardened or cracked seal.
• Loss of sealing performance at the valve cover.
• Engine performance issues related to degraded ignition-area sealing.

Installation Notes

Install during valve cover service or when replacing worn spark plug tube seals. Clean the sealing surfaces thoroughly before assembly and verify the seal seats evenly in the valve cover groove. Confirm application details for Mercedes-Benz C250 and SLK250 before installation.

Quality Assurance

URO lists a 24-month unlimited mileage warranty for this part. The OE-style seal profile and heat- and oil-resistant gasket material are specified to support consistent sealing performance in engine service.
