I recently bought a Japspeed rad to replace my split Apex one and they're not the same. I'm guessing the Apex rad split because I had no coolant in it over the winter due to changing the turbo and not using the car. I tried to order another one a couple of weeks back but there's no stock till May I was told so I bought the Japspeed one instead and the fit is far from perfect, it doesn't line up with the support brackets atall and I'm seeing higher oil temps, nothing dangerous though, compared to the Apex rad.
