Description
A stock filler neck is often the first casualty in a high-performance build—corroded, cracked, or simply inadequate for custom cooling systems. The Moroso 63466 replaces it with a heavy-duty billet aluminum solution that integrates seamlessly into your cooling circuit while offering the durability to handle aggressive track conditions and custom engine bay layouts. This bolt-on upgrade eliminates guesswork and delivers the reliability you need when every degree of coolant temperature matters.
