The S58 cools through three frontal radiators, one large central unit and a smaller auxiliary radiator in front of each wheel, and the factory auxiliaries pair slim cores with plastic tanks that fall behind once the engine is tuned. do88 replaces both sides with a dual row 48mm core carrying 43 percent more core volume than the original and 13 percent more active cooling area, built in full aluminium with TIG welded end tanks and greater fluid capacity. Both radiators are drop-in on either side, supplied with CNC machined mounting brackets and OE style quick connect inlet and outlet fittings, and the factory rock guard reattaches for debris protection.
