Designed to replicate the original engine compartment labelling, this sticker is positioned on the inner surface of the rear engine lid, where it provides factory specification information relevant to the vehicle's engine and exhaust system.

The Porsche 911 (964) was supplied in several market-specific configurations, with differences in emissions equipment, exhaust settings and engine specification information.

To identify these configurations, Porsche fitted designated information labels to the vehicle during manufacture.

The 96400610902 sticker is associated with 1990 model-year vehicles built for the Australian, United States and Canadian markets, subject to the applicable factory specification.

These labels are particularly important during the restoration of classic Porsche vehicles, as they help preserve the original engine compartment appearance and the information associated with the correct production specification.

Over many years, the original engine specification sticker may deteriorate because of heat exposure, moisture, cleaning products, abrasion or previous repair work.

The printed information may become faded or unreadable, while the adhesive may lose its effectiveness and allow the sticker to lift or peel away.

Engine lid replacement, repainting and body restoration can also result in the original sticker being removed.

Replacing a missing or damaged label helps restore the factory-style appearance of the engine compartment and preserves the intended identification information.

This component is especially relevant to Porsche 964 restorations, concours preparation, engine lid refurbishment and repairs where original decals have been lost or damaged.

What This Product Does:
The engine specification sticker displays factory engine and exhaust-related information for the applicable Porsche 964 model and market specification.

It is a passive identification label rather than a mechanical or electrical component.

Its main functions include:

• Displaying engine information: Presents the relevant original engine specification details.
• Identifying exhaust-related specifications: Provides information associated with the original exhaust and emissions configuration.
• Supporting vehicle identification: Helps distinguish the correct factory specification for the applicable model year and market.
• Preserving factory information: Maintains an information label originally specified by Porsche.
• Supporting restoration accuracy: Helps return the engine compartment to an original-style appearance.
• Assisting inspection: Makes the displayed engine information available for visual reference.
• Completing engine compartment presentation: Replaces an absent or deteriorated factory-style decal.
• Supporting documentation: Provides a reference label alongside the vehicle's original service and technical information.

Symptoms Of Wear Or Failure:
Engine specification stickers are exposed to environmental conditions within the engine compartment.

Although they have no moving parts, they may deteriorate through age, heat and repeated cleaning.

Common signs that the sticker needs replacement include:

• Faded printing: Text and markings become difficult to read.
• Peeling edges: The adhesive begins to separate from the engine lid surface.
• Cracked label material: Age and heat exposure may cause surface cracking.
• Missing sections: Parts of the sticker may tear or break away.
• Discolouration: Heat, cleaning chemicals or contamination may alter the original appearance.
• Adhesive failure: The sticker no longer remains securely attached.
• Wrinkled surface: Material deterioration or poor previous installation may cause distortion.
• Scratches and abrasion: Contact during cleaning or maintenance may damage the printed information.
• Oil or grease contamination: Deposits may stain the sticker or obscure the text.
• Water damage: Moisture exposure may affect printing or adhesive performance.
• Incomplete information: Printed details may have become partially illegible.
• Missing original sticker: A previous engine lid repair or repaint may have removed it.
• Incorrect replacement decal: The vehicle may have been fitted with a label intended for another year or market.
• Poor engine compartment presentation: A deteriorated sticker may detract from an otherwise restored vehicle.

Why Replacement Matters:

Restore Original Engine Compartment Appearance

The original Porsche engine compartment contains several factory information and identification labels.

Replacing a damaged sticker helps recreate the appearance of the vehicle as originally supplied.

Preserve Engine Specification Information

A legible engine sticker provides a convenient visual reference to factory specification information.

Replacing an unreadable label restores the ability to see that information in its intended location.

Support Accurate Classic Porsche Restoration

Correct decals can be an important detail during restoration work.

The proper model-year and market-specific sticker helps preserve the authenticity of the finished engine compartment.

Replace Labels Removed During Repairs

Engine lid repainting, accident repairs and panel replacement frequently result in original decals being lost.

A replacement sticker allows the engine lid to be completed after refinishing.

Improve Presentation

Faded, peeling or damaged decals may detract from the appearance of an otherwise well-maintained Porsche 964.

A clean, correctly applied replacement helps provide a tidier finish.

Support Concours Preparation

For owners preparing a vehicle for a classic Porsche display or concours event, details such as correctly positioned information stickers may contribute to a more factory-accurate presentation.

Address Age-Related Deterioration

Original 1990 labels have been exposed to decades of use and environmental conditions.

Replacement may be appropriate where the printed information is no longer legible or the label has suffered adhesive failure.

Maintain the Correct Market Specification

Selecting the correct label helps avoid fitting a later-year or different-market sticker that does not correspond to the original vehicle configuration.
