We've taken input from guys running big turbo setups on this one. The integrated filler now clears up more room for big turbo setups. The filler neck comes off the top of the housing and can be used to relocate the radiator cap to a higher point on the engine itself. The new location is the highest point of the cooling system and allows air pockets to easily escape during the coolant bleeding process. The Filler Neck is also available with standard 1.25" hose or in 12AN and 16AN sizes and was designed for use with an OEM 92-00 Honda Civic radiator cap. This part will be very helpful on an engine that already has a bad reputation for coolant bleeding.
