Here is the K-Tuned Upper Coolant Housing. With applications for both K20 and K24 engines, these housings will provide several unique advantages over the stock units. The hose outlet on the K-Tuned housing pivots slightly, allowing approximately 15 degrees of angle adjustment. This is helpful when compared to the fixed the factory outlet that always seems to put the upper rad hose in the path of the intake piping. There are three available hose outlets to work with any radiator hose setup. Choose the standard 1.25î rad hose outlet for use with regular rubber or silicone rad hoses. Switch to our optional 12AN or 16AN fittings for use with upgraded hose and fittings that are also available from K-Tuned.
The K-Tuned Upper Coolant Housing will compliment our Swivel Neck Thermostat and our Water Pump Block off Plate. All of these parts allow plenty of options for custom and race engine cooling setups.
