Detailed Product Overview

This INA timing chain, part number ZC0250, is engineered for precise timing control in the upper left position of the engine. It is a fitment-specific replacement for vehicles including the Audi S5, Audi A6 Quattro, Audi S6, Audi A8 Quattro, Audi Q7, Audi R8, Audi S8, and Volkswagen Touareg, helping maintain proper camshaft synchronization in the valve train. The ZC0250 timing chain is a practical choice when servicing timing components on these applications and is identified by INA Global Number 553 0250 100.

Common Uses

• Replacing a worn or stretched left upper timing chain
• Restoring accurate valve timing on Audi S5 and Audi A6 Quattro engines
• Addressing timing noise from chain wear in select Audi V8 applications
• Servicing upper timing drive components on Volkswagen Touareg models
• Correcting timing-related drivability issues tied to chain condition

Installation Notes and Tips

Verify engine code, model year, and left upper position before ordering. Timing chain service requires precise alignment of timing marks and careful inspection of related components during disassembly. Follow the vehicle service procedure for tensioning and timing verification after installation.

Quality Assurance

INA timing chains are manufactured to OE-quality expectations, with plates and pins heat treated to specified hardness for durability and performance consistency. Part number ZC0250 is backed by INA engineering standards for timing chain applications.
