As above, get a proper heat shield, it will be more effective and won't look like someone's dropped their sandwich into your engine bay
What did you use for the cold air feed and where did you get it from?
I was going to take a cold air feed pipe to the lower grill too.. but this talk on ukmivs about water can get in engine stuff has put me off..
For it to suck water up you'd have to drive through a huge puddle and completely submerge the filter, anyone who does that deserves to have their engine flooded
