A while back I was asking for information on air filters for TR3 equipped Plus Fours and recieved a lot of feedback, for which I was very thankful, but I wasn't completely happy with the idea of hurting the bonnet side panel.
In the interm I also encountered a problem with manifold heat boiling off fuel in the float chambers during hot weather.
After a bit of design work and some metal bashing I ended up with what I think are acceptable solutions for both issues.
Here is a link to the page on my site that explains how the work was done.
