Mishimoto Billet Aluminum Coolant Fill Inlet

The Mishimoto Billet Aluminum Coolant Fill Inlet (also called a coolant filler neck or coolant fill neck) replaces the factory plastic fill inlet with a more durable aluminum part.

Key Features:

• All-aluminum construction for higher durability than stock plastic
• CNC cut and bent for proper sizing
• Includes a replacement cap, as documented for Mishimoto's coolant fill inlets
• Designed and tested to work with OEM hoses and Mishimoto replacement silicone hoses
• Durable finish for long-lasting appearance
• Easy installation
• Backed by the Mishimoto Lifetime Warranty
