Product Details

The Wahler 0PB 121 110 A is an OE-quality engine coolant thermostat engineered to maintain precise operating temperatures in Porsche flat-six engines. Manufactured in Germany, this thermostat is a direct-fit replacement for the Porsche OEM part and is produced by Wahler (a BorgWarner brand), a trusted supplier of original-equipment thermal management components.

The thermostat regulates coolant flow between the engine and radiator, keeping the engine within its optimal temperature range for maximum efficiency, performance, and longevity. A properly functioning thermostat prevents overheating and ensures the engine reaches operating temperature quickly for reduced wear and emissions.

Key Features:

  • OE-equivalent replacement thermostat for Porsche applications
  • Manufactured in Germany to original equipment specifications
  • Wahler (BorgWarner) OEM-quality construction
  • Direct drop-in fitment — no modifications required
  • Restores proper coolant flow regulation and engine temperature management

Part Number Cross-Reference:

  • Wahler MPN: 411076.104D
  • OEM Part Number: 0PB 121 110 A (also: 0PB-121-110-A, 0PB.121.110.A, 0PB121110A)
  • Porsche OEM: 9A7 121 110 00 (also: 9A7-121-110-00, 9A712111000)
  • UPC: 4014427165552

Installation of this thermostat requires draining the cooling system beforehand, and a new seal (Porsche part 0PB 121 688) is recommended at the time of replacement for a leak-free installation.

Shipping was fast and efficient! Very happy that the fuel pump I ordered was available and arrived in perfect condition. This was a quality fuel pump that was difficult to find and was very pleased with the procurement of my order. I will use THMotorsports again! Thank you.

Good

Paid for 2-day shipping but it took 4 days. I have not used the Simrad GPS yet so I cannot comment.

Very excited, can't wait to get them !

Boatplicity shorted me one saddle float. I called customer service to see if it was backordered, I spoke with Joy and she was a big help and i had the 4th float within 2 days.

Great price with free shipping

Ordering was easy.
