K-Tuned KUW-24T-F02 K24 Upper Coolant Housing w/ Side Filler Neck K24A2 K20Z3

Upgrade your K-Series cooling setup with this K-Tuned KUW-24T-F02 K24-style upper coolant housing with filler neck. This is the previous side-filler-neck version, as shown in the product photos.

Important: K-Tuned has updated the design of newer upper coolant housings. The newer version routes the filler neck upward from the top at an angle. This listing is for the older KUW-24T-F02 version where the filler neck / fitting comes out from the side.

This K-Tuned upper coolant housing is designed for K24-style cylinder head cooling setups and is commonly used in K-swap builds, custom radiator hose routing, turbo setups, race cars, and cooling system conversions. The integrated filler neck setup helps move the fill point higher in the cooling system, which can make coolant bleeding easier on K-Series engine swaps.

This kit includes the upper coolant housing, filler-neck components, OEM-style coolant fitting, 16AN fitting, standard hose fitting, and hardware shown in the photos.
