PVC pipe is great stuff for making intake snorkels but, in this case, it would have been very difficult to route a large enough pipe from the fog light area to the airbox. The problem is the limited selection of angles available in PVC bends.
An easier option is flexible pipe. But note that not all flexible pipe is the same - many have a near-smooth inside wall (which helps maintain airflow) while others are very convoluted (which restricts air flow). Cost also varies massively so shop around. Our 3 inch flexible pipe had been sitting in the shed for several years so it cost nothing.
With the original intake snorkel removed, we could fit the end of our flexible pipe to the airbox. This was easy in the case of the VR4 – our flexible pipe slipped tightly over the snout of the airbox.In some vehicles you might be able to run the flexible pipe from the airbox to the front of the car without cutting any metal. However, in the VR4 we were forced to put a hole through a difficult to access section of the inner guard alongside the battery tray. Note that there’s plenty of support structure in this vicinity, so you can get away with creating a 3 inch hole.
