Fresh air.
while i’m relocating the battery i decided to try forced fresh air to engine bay to see if there are any clear benefits, the drivers high beam is perfect and has a clear shot for sidedraft, i’ll be adding some duct work and perhaps removing the passenger side high beam as well. i went with store bought funnel which fit the OE rings and mount but i did need to modify the bulb cups. the screen is readily available for motorcycle light protection, the factory bmw bulb is 5.75″
