• Billet tanks CNC machined in-house from aircraft grade 6061 T6 aluminium

• M6 internal threads in each end tank for ease of mounting 
• Pressure tested after welding 
• 10AN hi flow adapter fittings included. The common adapters aree somewhat restrictive so Green Brothers now manufacture these in-house with a 12.5mm internal diameter for maximum flow

Two configurations available:

Double Pass - Direct replacement for factory Mazda oil coolers
