Please be very careful with KOYORAD product, they never have production for Proton or Perodua Cars, u may directyly refer to KOYORAD website, those cheap with logo KOYO is fake/imitation product.
But for ur car, u can use EVO1/2/3 KOYORAD. Normal Type RM900. Peformance KOYORAD RM1850....Item is 100% genuine KOYORAD.
Consider this, a front wheel driven Volvo with 306hp, 400Nm. Who knew, that a Swedish marque known for building safe cars would put that kind of power on the front wheels, and is that even realistic? We’ll come to that later.
