I will look up the specs on the oil cooler I am running with the DHM crash bar and big IC, I did an oil cooler upgrade as soon as I bought the car, it was lots of fun figuring it all out, finding the part to install the plate took even longer so I had to do that part later..it sure would of been nice to just buy a kit even if I had to still make my own mounts to install the cooler.
NOTE:
Dirt cheap and easy upgrade, use a bigger oil filter, adds a bit of capacity, a little more surface area for a tiny bit of cooling and more filtering with little added weight. I use NAPA Gold filters, made by WIX, widely known as a very good filter for a very good price, an even larger unit can be used than this one but I had spares from my first install when I had to leave the stock cooler in place, just disconnected, until I found the part I needed to remove it and install just the plate.
# 1355
NOTE 2:
Free way to increase air flow in and out of all the coolers.
1) Drill big holes in the crash sensor mount bar, or as I did later build a much smaller new one.
2) Drill holes in the lower radiator support between the grids, I used a step bit for this, it opens up quite a bit of flow and removes a little bit of weight.
I will post a picture when I find one.
NOTE 3:
SEAL up everything you can so no air can go around the coolers, ABS sheet works great as easy to cut, low weight, easy to mold using a heat gun or carefully with a propane torch.
