This housing directly replaces the OEM cast unit and is available in either -16AN or 32mm hose end specific versions, with no leak-prone modular fittings to deal with or the frustration of trying to remove the AN line & having to fight with 2 large wrenches in a very tight area to get the line off without taking the fitting with it.

Includes an 1/8 NPT accessory port for a cooling system pressure sensor or temp sensor (not included) along with provisions for the OEM cooling fan switch and engine harness ground.

Product Features: 

  • Precision CNC machined from 6061-T6 billet aluminum
  • Black Anodized finish adds durability and eliminates corrosion
  • Laser-etched SFR logo
  • Dual bolt pattern fits both B & D Series (Except D16Z6)
  • OEM fan switch port
  • Engine harness ground provision
  • x1 1/8 NPT accessory port (use for coolant pressure or temp sensor)

Includes:

  • (1) Billet Thermostat Housing
  • (1) 1/8 NPT Pipe Plug

Fitment:

  • 88-01 B-Series engines
  • 88-00 D-Series engines (Except D16Z6)

Notes: If installing a pressure sensor (NOT INCLUDED) directly into the housing rather than remote mounting with a -4AN line, you will need to use a small diameter body sensor such as the AEM stainless pressure sensors for fitting/hose clearance.

-16AN hose ends are large and may require adjustments to other items such as fill necks, scattershields, etc for clearance.

Does not block RFID scanners
Does not block RFID scanners. I literally scan my badge into work every day through it. Other than that, they are nice wallets, but only last about 3 years before the leather starts crumbling off. This is the second one I have bought. 2 Stars because they only last about 3 years and does not block RFID scanning as advertised.

2nd time purchase in 7 years.10 stars!
This wallet design is fantastic. Compact, front or back pocket use. Has a ton of storage even though it doesn't look it. Last one lasted 7 years of abuse and use. I ordered 2 in case these never get made again. Grab one, best wallet and real durable leather, not fake leather.
