*also posted on cumminsforum.comHow is the BHAF affected by driving in heavy rain? Is there a possibility that it would get wet from the water going up through the wheel well past the shock tower? If it gets wet will it ruin the paper element? I don't run a heat shield, but do they help keep the water out of the filter? Thanks!

Now notice you towards the middle of the manifold and mounted in a area away from coolant passages... But 2nd Gen is mount at the end of the manifold (#6) with a coolant passage right next door... I think location has a lot to do with it...

It must, 2nd gens appear to only get the #6 airflow to cool it, where 3rd gens get 4,5,6 airflow to cool... But its amazing to me that it would rise 30* in 6" but sensor placenemt is key.. How much hotter does yours get at sustained boost when towing?

Like coming home with a trailer loaded and the bed loaded I saw about +45*F over outside air and was boosting about 10-15 PSI all the way home...
