Item 1 Brain shield. This little plastic box stops water dropping onto the elec connector and the ECU underneath. Push fit onto existing studs.
Item 2- scuttle drain hose. This is a push fit on the scuttle drain spigot. Routes water to back of engine instead of dumping it over inner wing cladding, which leads to several issues.
Item-3 Scuttle drip tray. This directs water to the back of the engine instead of it cascading over the air filter and fuel injector. Push fit onto scuttle brackets. Performs similar function to rob drew tray but doesn’t restrict airflow at back of engine.
These items are cheap, easy to fit (no screws) and can be pulled off prior to having van serviced if you are worried about warranty. I have had them fitted for a couple of months now. Very effective.
