This high performance heat exchanger replaces the OEM version and provides an increase in cooling efficiency to lower engine air intake temperatures. This makes it ideal for tuned engines where increased intake temperatures can reduce power and cause engine damage. This heat exhcanger has been proven to consistently reduce air intake temperature by 10 deg C, improving power output.Triple pass flow for maximum heat dissipation and reduced engine intake temperatureUltra efficient fin design provides maximum surface area68mm thick dual dual row core provides maximum surface area for the space availableReplaces OEM heat exchanger with no modifications required to fitHigh quality aluminium TIG welded constructionHand polished mirror finishIncludes a rock guard to protect against damage from stones.Cars which have been remapped and running higher than standard boost levels will benefit from this performance heat exchanger. The OEM unit is O.K for stock cars but struggles to cope with the inc
