Here we go, another piece of the puzzle arrived: A Koyorad Japan (Koyo) Aluminum Racing radiator. The great thing compared to the OEM Radiator is that this one is a bit thicker and has a crossflow-design which means better cooling efficiency. Also i was impressed about the weight. this thing is about 1/4 the wheight of the OEM Item. Great bang-for-the-Buck deal in my opinion! typical japanese manufacturing quality: Also  had to buy a koyo radiator cap because the OEM cap would not fit: have some other news soon, but it’s currently just a bit too cold out in the garage 🙂
