The CSF all-aluminum filler neck with high performance radiator cap is an easy and effective upgrade. It's a great combination with the stock radiator or even better with a CSF or other high performance radiator.
- Mirror finish polish
- Drop-in fit, no modifications to install - simple plug-n-play
- Comes with a mini sized filler neck. The original filler neck is a micro size (flat edges on cap). The mini size is more popular (rounded edges on cap).
