I assume my '14 Nismo has an OE cooler. The thought behind the spacer was this. This one increases capacity by 1 Liter. That's an increase of 20%. So, oil should be 20% cleaner between intervals. And with E85, injecting 25% - 33% more fuel, on top of the fact I'm boosting (ever more fuel), could cause some fuel contamination / "bore wash". It should also be 20% more resistant to increasing in temperature. It *may* not effect the ultimate temperature, but it should take longer to reach that point. For now Im thinking spacer, and see what happens. Im already planning to change oil every 3333 miles if I do this. Also, it's only $130 right now. Black Friday might change some of these prices. The down side is, if I end up with a cooler too, I just spent $130 I didn't need to because I agree I don't need both.
