**Although it is not recommended, we can manufacture these intercoolers with the smaller diameter 2.5? (63mm) inlet and outlet sizes to allow for some compact installations. However, to achieve the maximum flow and power benefit from this intercooler core, we suggest 3.0? (76mm) outlets, in either push-on hose style, or Plazmaclamps**
Please be advised that the flow rating figures for this intercooler is based on CFM flow figures and experience. These figures might not be correct if a larger capacity engine (6 Litre +) and/or larger body 90mm + front blade size turbocharger is used. Please contact us if you fall into this category for intercooler requirement.
