URO URO-011191 Spark Plug Tube with Viton O-Rings

The URO URO-011191 is a direct replacement spark plug tube designed to restore proper sealing and prevent common oil contamination issues in the valve cover. This OE-style plastic tube creates a critical compression seal between the valve cover and cylinder head, preventing oil from seeping into the spark plug wells.

Key Features:

• Supplied with high-quality Viton O-rings for superior heat and oil resistance
• Replaces broken or cracked tubes that can create vacuum leaks and degrade engine performance
• Prevents misfires caused by oil buildup around spark plugs and ignition wire connectors
• High-quality plastic material resists engine heat and oil degradation
• OE-style design ensures proper fit and compression seal

Leaking or damaged spark plug tubes can allow oil to contaminate the ignition system, leading to misfires, rough idle, and decreased performance. This replacement tube restores the factory seal to maintain optimal engine operation. Cross-references to BMW OEM part number 11127835170.
