Product Details

The Genuine Porsche 999-652-811-40 is an OEM replacement seal designed for the engine coolant temperature (ECT) sensor electrical connector. This small but critical sealing component prevents moisture, dirt, and engine bay contaminants from entering the sensor connector, ensuring a reliable and corrosion-free electrical connection at the coolant temperature sensor.

Key Features:

  • Genuine Porsche OEM part — engineered and manufactured to original factory specifications
  • Provides a weatherproof seal for the coolant temperature sensor connector plug
  • Protects against moisture ingress, corrosion, and electrical faults at the connector interface
  • Direct factory-fit replacement — no modification required
  • Durable rubber construction designed to withstand under-hood heat and fluid exposure

Using a genuine OEM seal ensures the connector maintains its original environmental protection rating and delivers long-term reliability. This part is ideal for restoration, preventive maintenance, or replacement during coolant temperature sensor service.

Great product!

Was quick and easy

Great price, much cheaper than other retailers. Also, the package got shipped within 24hrs.

Best price for an expired item around, though more options in shipping would be appreciated. Ordered saturday night and item shipped tuesday morning, saved about 30% off of the originally planned purchase price. Definitely will use them again in the future.

I enjoyed the quick and simple the checkout process

good and fast
