Maybe slightly higher tech than the tights but K&N do what's called a filter sock to sit over their filters and protect it from water spray which in time can wash the oil from the element.

Bit like this, there's one in the garage somewhere but off a turbo'd bike



These are usually more necessary for filters out in the open and possibly prone to water spray - dunno if this is the case with the DS application with the intercooler deflector removed as they recommend during fitting?

If i'm right the DS filter doesn't sit as low as K&N have it with their Gen 2 kit, and the only cars i'm aware of which have had problems with that kit did unfortunately end up driving through very deep water. Don't think there's much advantage in wrapping the turbo pipe, the intake air is still going to get cooked by the turbo before getting cooled through the intercooler.

The air won't be go the pipe long enough to get warm. As said, the turbo will heat up the air anyway so wrapping the pipe will not have an effect. The filter sits higher than the k&n and you have an undertray stopping the worst of the water. The water would have to be up to the doors for it to be sucked in

Water does get into the area that the filter sits. but only a small amount. but as said above for water to get 'sucked' up it would take a huge puddle and some bad awareness for it to happen. I have just had the DS fitted i am not sure how much higher it is then the K&N but the K&N sat pretty high anyway IMO so you should be ok with the DS one.

Wearing tights might draw some funny looks off people

Thanks for mentioning this simo, its just made my mind up! DS induction kit hear I come. I should be alright because the undertray will protect the spray and it sits higher up than what I thought. I'm also going to get one of those filter socks from K&N so it keeps it cleaner. The old rs focus used to have something similar to this I think.
Theres a part of road near me that always has surface water everyday and sometimes its a very large 4 inch deep puddle and I was worried about it spraying up or nearly touching the filter. Should be fine though. Even if I gunned it through a puddle it should be ok.

Thanks for the other replys guys.

Ive run the K&N 57i kit since April 2007, covering 44000 miles through rain and puddles including a few days going round the Nurburgring in the conditions pictured below! I have never had any problems! Unless you drive through a river nor will you! Somebody running a completely standard car ruined their engine through hydrolock so it isnt down to where the filters mounted its down to how stupid you are lol!

Them pics are good enough for me to prove that rain and puddles are ok, I'll just stay out of rivers.
And if nobody reports problems today after the snowy weather its almost certain that its safe to have an open cais.
I'm going to order it next week when funds and mrs allow. And sell my GGR thats broke on the piece between the cold air feed hose and cais. GGR have said £50+vat+postage for the new redesigned part. Thought I would have got it free but no luck.
