13BREW Front Iron Coolant Passage Block-Off Plate

Keep it sealed where it counts.

The 13BREW Front Iron Coolant Passage Block-Off Plate caps off the coolant port on the front iron of your rotary engine during storage, display, or mid-build downtime. No more open water passages inviting corrosion and contamination into your cooling system.

Why you need it:

Exposed coolant passages are a rust magnet. Moisture in the air is all it takes to start corroding the inside of your water jackets — and once that starts, it doesn't stop. This plate seals it off clean so your front iron stays protected while your engine sits.

Features:

• Direct fitment over the front iron coolant passage
• Prevents moisture intrusion and internal corrosion
• Clean, purpose-built look for storage and display engines
• Simple bolt-on install — no modifications needed

If you're building a showpiece motor or shelving your engine between projects, the 13BREW Front Iron Coolant Passage Block-Off Plate keeps water passages sealed and corrosion-free.
