Hey Chris,

Are you still making inlet diffusers?

I bought a used 320 and we are having no luck getting sufficient cooling from the original firewall oil cooler installation.  I want to try using diffusers and a front-mounted oil cooling arrangement.  Not ready to give up and go with a full plenum just yet...

If you (or anyone else, for that matter) still has a couple of these lying around please contact me!
