Just wanted to see who else has done this on their AT rx8 and see what your impressions were before and after the install?

One thing I notice is that when the car is at running temperature the idle seems to be a bit smoother. I don't have temp. gauges in the car as of yet so I don't have any before and after temps. Does anyone on here know how much it brings the temp. down adding the second oil cooler? I have read 30 degrees F but do not know how accurate that is.

One other thing I would like to know is does anyone else notice that the oil at every change is dark? Not black but definitely a lot darker than I would expect considering I change my oil every 3k miles.

Cheers

 

We did this mod to a friend's RX-8. On track days his oil temps were about 40-45 degrees cooler after the install. Very worthwhile modification.

 

Found a thread on this exact issue by some guy I know.............

During an oil change, you can't get all of the old oil out since it is stuck in the oil coolers. You'll likely only get a little more than half of it out with the 2 coolers you have now.

Its not a big deal, oil color is far from an indication that it has lost its lubricating properties.
