Alternatively a shed load of heat shielding and I would seriously look at a NACA duct on the bonnet to supply air to the filter.rwilsonrs4 wrote:having looked back through the build could you not reposition the filter by shortening the intake hose and put it under the wheelarch at the corner , even get a 90 or 120 deg elbow
There isn't many places that will be drawing in air except that which has passed through the front grill so could already be heated by the radiator.
I'd be looking to fabricate an airbox surround for it to blank of as much heated air as possible fed by a duct on the bonnet and also the wheel arch. This would also protect the electrics from any water entering the bonnet vent.

Doesn't have to be big to have a big impact.
