An alloy male to male bayonet style 65mm coupler with inline bayonet nipples.
This coupler replaces the pressed steel hose coupler that is found on the VW / Audi/SEAT/Skoda 130 hp diesel engines ( ARZ engine code). The coupler connects the boost pipework to the intercooler ( see diagrams below ) This replacement eliminates the problem of the OEM couplers blowing apart. This upgrade is advisable to all software upgraded, or tuned engines and higher mileage standard vehicles.
Please note Two couplers are required of different design ‘M’ and ‘N’ These can either be purchased separately or together (FMABHCMN) at a reduced cost.
PLEASE NOTE: THE ORIGNAL O-RINGS/SEALS MUST BE RETAINED FOR USE ON THE FORGE HOSES
