The Process West Stage 2 Front Mount Intercooler Core for the Ford BA/BF Falcon is a 500 x 360 x 80mm bar & plate core, with hi-flow polished aluminium end tanks. This allows for smooth flow and effective cooling of the charge air entering the engine. The intercooler core is available in both black powdercoated or silver finish. CROSS OVER PIPE KIT - This crossover pipe is designed to work with the Process West Stage 2 Intercooler Kit and Under Battery Cold Air Intake. It can also be paired with the "around the battery" Intercooler Piping Kit which will enable fitting of the under battery cold air intake even with the stock intercooler in place.The upgrade crossover does 2 things - Removes the factory restrictive cross over pipe, Allows fitting of the Process West Under Battery Cold Air Intake. This product opens the door for a great package that consists of the Stage 2 Intercooler Kit, Cold Air Intake and Crossover. Also worth noting is the bonnet clearance above the crossover. I have made the unit as large as possible but still left 10mm clearance to the bonnet... something which can not be done with bent aluminium tube (it can be done but you a left with a very awkward looking pipe). UNDER BATTERY COLD AIR INTAKE - Our air intake system is designed to be used in conjunction with our billet plenum or in other custom set ups. It utilises the space normally taken by the factory intercooler plumbing under the battery tray.
