I asked rhdjapan.com for the combination brake/oil cooler ducts but apparently Mazda makes a separate oil cooler duct now for the 99 spec bumper?! The part number for the 99 spec oil cooler duct is not the 93-95 one is it? The link is below, thanks for the clarification.

Well, yeah, the 99 has much bigger inlets so the duct is completely different.

 

There is the brake duct and the oil cooler duct. Both are separate items on the 93-95 and 99-spec fronts.

nice i have the R E Oil Cooler Duct (larger overall ) but soon to replace with this to truly complete the 99spec

 

do both of these parts fit or do you have to use one or the other?

 

Gene, don't waste your time. Fitment is blah. In fact, the term used by some members was "generic" lol. And Chuck's were great but fitment wasn't the best. I'm already making much larger and better fitting 99spec brake and oil ducts. Just be patient w/ me

sounds good

 

Shouldnt be hard to fab up some ducts out of sheet alumium or glass..

BTW...does anyone know what temperature the oil cooler thermostat is set to? ie what temp does it open/close?
