AE-2 for Aluminum Pencil Anode — Replaces E-2, E-2Z, CMEZ2 Anode Only

Protect your engine’s heat exchanger from corrosion with the AE-2 aluminum pencil anode. Designed as a replacement for multiple OEM-style pencil anodes, it provides reliable corrosion protection in saltwater, brackish water, and freshwater applications.
