• Hydraulic oil-fed design provides consistent, automatic tensioning
• Genuine Porsche OEM quality ensures precise fitment and reliability
• Engineered for high-performance air-cooled Porsche engines
• Helps eliminate cold-start chain rattle and timing chain noise
• Critical component for proper engine timing and longevity

This timing chain tensioner is part of the pressurized lubrication system upgrade for classic 911 models. Two tensioners are required per engine (left and right side). When updating models with original wide flange hydraulic tensioners, additional spacers (930-105-513-00) and sprocket supports may be required for proper installation.
