K Series Upper Coolant Housing w/ Filler

  • $95.00

Precision Works K Series Upper Coolant Housing with Built In Filler Housing

Applications: K20A, K20A2, K20A3, K20Z1, K24A1 cylinder heads.

Note: Does not fit with PRB manifold and throttle bodies with cruise control.

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 comes standard with 1.25" hose fitting, but is also available with a -16AN fitting. It was designed for use with an OEM 92-00 Honda Civic radiator cap.
