Just did my Injen CAI and oil cooler install on my Nismo. The CAI was fairly easy except for all the bolts and clips. The oil cooler was a different story. Because the Nismo has a body damper the normal oil cooler installation location is problematic. I ordered a series 9 setrab cooler from BAT along with their mounting bracket. Also found a way to route the oil lines thru the frame member so no cutting involved. After installing the cooler plus hose plus larger 1010 filter I am now at 6.2 quarts capacity. Cruising at Interstate speeds I am running about 25 degrees cooler. Yee ha! Track day in a little over two weeks, can't wait. Rather than post the pics here I put them in my album. Anybody else done a cooler install on a Nismo? Seems kind of funny that the Nissan motorsports cooler won't fit on the Nismo?
