Manufactured from high-quality automotive-grade EPDM rubber, the seal offers outstanding resistance to UV exposure, ozone, moisture and extreme temperature variations. Supplied in a 3750mm length, it is precision-profiled to replicate the original factory design, providing excellent flexibility, long-lasting sealing performance and straightforward installation during restoration or maintenance.

What This Product Does:

• Creates a weatherproof seal between the bonnet and body.
• Prevents water, dust and road debris from entering protected areas.
• Helps protect the luggage compartment or engine bay from moisture.
• Reduces wind noise around the bonnet.
• Cushions the bonnet during closing to reduce vibration.
• Maintains correct bonnet alignment and fitment.
• Helps prevent moisture-related corrosion.
• Forms an essential part of the vehicle's body sealing system.

Symptoms Of Wear Or Failure:

• Water ingress into the luggage compartment or engine bay.
• Cracked, split or hardened rubber.
• Flattened or compressed seal profile.
• Increased wind noise while driving.
• Visible gaps between the bonnet and body.
• Loose or detached sections of the seal.
• Dirt and debris entering beneath the bonnet.
• Damp components or corrosion around the bonnet opening.
• Perished rubber caused by age or UV exposure.
• Bonnet vibration or rattling during driving.

Why Replacement Matters:

• The bonnet seal is continuously exposed to sunlight, rain, road salt, engine heat and repeated compression every time the bonnet is opened and closed. Over time, the rubber can harden, shrink or crack, reducing its ability to provide an effective weatherproof seal.
• A deteriorated bonnet seal can allow moisture and contaminants to enter the luggage compartment or engine bay, increasing the risk of corrosion, electrical issues and unnecessary wear of surrounding components. It may also contribute to wind noise, bonnet vibration and reduced refinement.
• Replacing a worn bonnet seal restores the weatherproof integrity of the bonnet assembly and helps protect the vehicle from environmental damage. The OE Match replacement provides factory-style fitment, premium EPDM rubber construction and excellent long-term durability, helping preserve the originality, reliability and value of your classic Porsche.
