what does the underside of your splitter look like where the oil cooler outlet is? i imagine its pretty hard to make that area a high pressure zone, but without proper ducting, air might be just flowing around it.
the oem undertray on thse cars is decently form fitting with minimal leaks for what it is. i feel like distrupting the packaging is problematic.
