Vibrant Performance -4AN to M8 x 1.25 Metric Straight Adapter Fitting - 16603
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The Vibrant Performance 16603 straight adapter is a precision-engineered solution for plumbing high-performance fluid systems. This adapter allows for a secure connection between a -4AN line and an M8 x 1.25 metric port, commonly found on aftermarket oil pumps, fuel pumps, and fuel filters.

This component is designed for easy assembly and consistent flow in demanding automotive applications.
