Expanding on our knowledge in effective heat-exchangers (intercoolers and oil coolers), GReddy now offers a thicker core upgrade for your engine's coolant system. The core and end-tanks are made completely of aluminum and incorporate all of the factory mounting, fan shroud, cap and connection points for an easy bolt-on installation. The TIG-welded, GReddy embossed, end-tanks also feature a pre-drilled and tapped port for installing an aftermarket temperature probe (like our GReddy Temp Gauge).
