Riding on 40c days here so if it's going to help keep the air cooler then its nothing but a good thing.Hope this helps your queries, Bit biased here but apart from looks you get air cooler from the front direct onto the filters instead of drawing hot air from the top of the engine and Ive done plenty of miles in the rain with some pretty heavy downpours with no issues with a RamAir filter
