just keep the filter where it wont get too wet and too dirty, yeah AEM boasts big HP, but its always on a dyno, with a fan in front of it. i have had just as good of time slips with an HP cold air which is some no name brand as AEM, you will make more torque with a drop in K&N. and heres a thought, how hot on a summer day do you think 6 inches above the black yop pavement really is?????
