Mine was fouling the stock airbox very slightly, so used some heat proof exhaust pad (usually made for motorbike exhausts) stuck to the airbox against the oil cooler line and its been fine. The thermostat hex thing corner was against another pipe too, although not common and Mike sorted that out quickly. Would recommend TD oil cooler kit overall, just don't need to worry now about track temps Sent from my Pixel 4 using Tapatalk
