Aluminum Zenoah G320RC / G320PUM Insulator Manifold Block with PTFE heat spacer gaskets for both cylinder and carburetor side.
This version is the exact same thickness (spacers included) as the stock manifold setup, so no adjustment is required in R/C throttle linkage setups.
Fits Zenoah G320RC / G320PUM engine only.
Does NOT fit earlier Zenoah RC models!
