do88 performance intercooler are an all aluminium construction with cad designed, flow optimized cast end tanks and optimized core design to achieve best possible cooling efficiency combined with lowest possible pressure drop!Always remember that the OEM intercooler was designed for the power level the car was built for and a power increase or even very hard use of the car in a standard version may cause that the OEM intercooler don’t have the performance you need. So only after engine software tune do88 performance intercooler will give a performance increase over the OEM intercooler!The OEM intercooler have plastic tanks that don’t keep up with higher boost levels very well so the do88 performance intercooler will also add reliability!A common misunderstanding is that an intercooler installed in this position cannot provide good performance and a front mounted intercooler / FMIC would be much better. But actually the do88 performance intercooler are far better than most FMIC installations where only a core with small front surface are possible to install and often also installed partially behind the bumper beam which will reduce cooling capacity even further and often cooling below the OEM intercooler are achieved.do88 performance intercooler comes with all hardware necessary for installation.This intercooler fits all Volvo S60 / V70 / XC70 / S80 turbo models with or without sensor on the intercooler outlet as it have this mounting plate but also include a block off plate that will be used only on cars without sensor mounted on the intercooler outlet.do88 performance intercooler installs in original position with original fastenings. NOTE! When installing this intercooler on a S60 R / V70 R the small auxiliary intercooler needs to be removed as it no longer will be used. On R-models the grille is a part of this auxiliary intercooler. This means when you remove this intercooler you will have to install an new mesh if you which to have a grille / mesh in this opening. You dont have to install a mesh, if you dont do this the bumper intake hole will just be open into the AC-condenser.
