So I just got back from a track day and wanted to replace my oil and upon inspection found that I have a leak in the oil cooler lines and unfortunately the dealership here doesn't have them in stock. So I'd like to know whether I should stick with OEM or upgrade to aftermarket and what are the options available ? I found a thread about oil cooler lines but for some reason I cant view it.

One last thing I need them yesterday as I have my annual time attack event in a couple of days and want to get whats available.

Thanks
Yousif
