Made here in the UK in our own workshop. These Honda K20 baffled sump kits are designed to fit inside the factory sump pan without any modifications. Located across the original sump pan inner webs and sized precisely so that the factory windage tray locks it in place when the sump is refitted. No drilling or welding is required, simple easy-fit design. A baffled sump is essential for track day cars and fast road use.
