SpeedFactory Billet Thermostat Housing Honda B-Series 88-01 D-Series 88-00 (Except D16Z6)

For those that wanted a premium billet option, we present the SpeedFactory Racing Billet B/D Series Thermostat Housing!

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 etc. (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, etc.)

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.
