Looking at the pics, it seems like the cooler isn't getting cool air. I'm sure there are still some benefits such as more oil in the system, but it still looks like a nice setup.

 

What about a filter for the metal shavings that normally collect at the bottom on the magnet?

 

Best to run filters - always, my install i used a filter before and after the pump, to prevent damage to the pump.

Question on temp was asked, my set-up has complete function, but as many as you know, my car see's more shows than the road. If your car is a daily / track best to install a temp sensor into the pumpkin (simply tap and place a temp probe into the diff - I believe Titan makes a kit and / or you can get one from GTM), so you dont have to turn it on and off by a switch as I do. No temp readings where taken.........

 

It's cooler air than it normally would be since it outside ambient air. When driving, the air hits that cooler like your front radiator. Even Nismo R34 Z Tune GTRs have theirs located out back like this.

Also, you do not need to run the pump unless you're driving the car hard, normal day to day routine, it's not essential to even turn it on at all.

Just FYI

 

Correct, Always run an inline filter prior to the pump. That's what I did, and it's super easy to do.


Also, if anyone out there is at all interested in setting up a kit, I can get you all the components you require for under $420
