The OE Match 99610444502 Heat Shield for Cylinder is a high-quality replacement component developed to replicate original Porsche specifications for fit, durability, and thermal protection. Installed on the cylinder head area, this shield acts as a protective barrier between the engine and sensitive ignition components.

Positioned directly over the ignition coil packs, this heat shield helps deflect radiant heat generated by the engine, preventing excessive temperature buildup that could affect ignition performance. It also provides protection against moisture and debris, which can contribute to premature wear or failure of ignition components.

Designed for both banks of the engine, this component fits either the left or right side, making it a versatile and essential part for maintenance or replacement. It is commonly used on Porsche 996 3.6L engines and 997 Gen 1 3.6L and 3.8L models, and supersedes earlier part number 99610444501.

Due to its location in the engine bay, the original shield is exposed to constant heat cycles and environmental conditions, making it prone to corrosion and deterioration over time. Replacing it with an OE Match unit ensures continued protection and optimal engine performance.

This heat shield protects ignition coil packs and surrounding engine components from excessive heat, helping maintain reliable ignition performance and component longevity.

Function
•  Shields ignition coil packs from engine heat
•  Deflects radiant heat away from sensitive components
•  Protects against moisture, dirt, and debris
•  Helps maintain consistent ignition performance
•  Reduces risk of heat-related component failure

Heat shields in this location are highly exposed to extreme temperature changes and moisture, making them prone to rust and deterioration. A damaged or missing shield can lead to overheating of ignition components, reduced reliability, and potential misfires.

Replacing the heat shield ensures proper thermal protection and helps extend the lifespan of ignition coils and surrounding components.

When to replace
•  Visible rust, corrosion, or deterioration
•  Missing or damaged heat shield
•  Ignition coil issues related to heat exposure
•  During coil pack replacement or engine service
•  Preventative maintenance on high-mileage vehicles
