there is the pic as promised.
Rather crude, rather quick to make and for under $20
will suit Weber air filters more so than every other std EA81
I just used the paper cardboard bonded foam core board rather than the PVC bonded board - sign board stuff from newsagents or stationers ~ $12 and about $5 for one length of the pipe insulation and some bastard put grey silicon cartridge back in clear section on shelf !
Is held down by fact smaller hole than air filter housing, so housing holds it down, and just squirtd out silicone where I wanted it, and shut bonnet down to hold all in place to set.
Need reflective foil or alloy sheet below to reflect more heat below.
It is MKII so should look better than MKI
