Fair to midland
I assume Vans firewall forward oil cooler kit?
Cooler, I think its a less expensive and efficient clone. I only use SW. I am cheap but spend my money where it counts.
The Firewall oil cooler mount kit is terrible. The idea is not bad just the parts which might work well for a Lyc 320. Search archives for more info. There are several extensive threads on how to remotely mount an oil cooler properly.
