It wasn't too hard to install... water pump here, water reservoir there.... and almost no piping! (this change from front mount to water/air was incredible, just cause of the piping lenght, my power band changed a lot! , no more low end torque, but much more top end! I had to dial the cam gear for less overlapping, to get back some low end torque)
I'm not sure, but it's almost sur that it's sold allready, I sold that:
water/air intercooler 16" X 4" > water pump (5year waranty)> Water reservoir aluminium> 2 X cooler 8" X 12" for 1000$ Canadian > almost 1000$ Aus
