Little update.
For those with fog lights and are looking to buy this HKS oil cooler it will not clear the turn signal connector unless you buy the harness from the non fog light model. The turn signal connector that connects to the bulb is much longer on the fog light model for some reason and I wasn't able to put the bumper on.
To be honest I have lost motivation to keep the build going as I'm constantly finding small issues like these turning me away from the car. Currently looking at purchasing a new vehicle so we will see where that goes.
