I installed an OEM oil cooler from a 1990 Eclipse. This is the air cooled cooler and not the cooler that utilizes coolant like every other year. I ran this setup on LILEVO1 and installed it better this time around. I even cut some underbody plastic and attached it to the cooler to better duct the air through the cooler. I plan on sanding, using putty, and touch up paint to make the bumper look stock. This will eliminate the jagged edges and turn them into smooth curves.

Parts list:
16mm x 1.5 to 8 AN Adapters x 4
Straight 8 AN coupler x 1
90 degree 8 AN coupler x 2
45 degree 8 AN coupler x 2
Few feet of 8 AN braided stainless line
