Air filter protection from road dust

The Sylva J15 was designed to take the 1.7L Sigma engine. In my interpretation of the engine install The air filter and MAF sensor ended up perilously close to the rear wheel. In inclement weather (in Scotland) it gets covered in water off the rear wheel. The problems are two fold 1) Air filter contamination 2) MAF meter reliability. The ECU in my  car is stock with a Puma Speed upgrade. As such it is a closed loop system with air flow as part of the Ford mapping. I decided to fence off the route for contamination from the back wheel. This is the penultimate winter mod as it is now on the cusp of Spring in Scotland.
