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

CLICK HERE TO ORDER TITANIUM INSTALLATION HARDWARE! (Order Qty. 2 bolts)

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.

This is a great brand! The products are quality, and well made! These pillowcases are extremely soft and comfortable! The fabric is luxurious! The colors that I ordered are true to description! And these pillowcases are generous with size - it isn’t difficult to put your pillow in th case!! The cases are not slick/slippery! They are soft and comfortable (I know I already said that, but it’s worth repeating!! They look great on the bead like a sham as well!! Best of all, they are more than worth the money! Highly recommended!!

So soft and cool on my face at night. Fit my pillows perfectly and don’t slip off. They’re thin but thick at the same time (if that makes sense), super breathable and clean well in the washing machine. I cosleep so stains happen and I love good quality fabric that doesn’t stain easily.

Decent quality, good color, bad shipping package

You pay for the quality you get. I think they’re thick & soft enough and the coloring is spot on. However, like other reviews, it was shipped not inside an Amazon box but the actual company slip packaging & the tape was already off with some of the pillow cover sticking out. They should change how they ship them, I would have given it 5 stars.
