Does the TRD CAI hurt or help the FJ while going thru water?
where do you base this info on? As far as I know all of the exposed electronics ore environmentally sealed, or waterproof. That is unless you fill the cabin up to the fjammer then you may have problems.:rofl:However, i think the snorkel is a little overkill for water as you have plenty of not waterproof electronics that are a lot lower than the snorkels intake.
I've seen independent dyno results adding 8hp with an opening in the air box. That's why you're seeing the newer models by Volant and AFE with a port on front.The only problem I can see is if you remove the lid you wouldn't get as good of a gas mileage as with the lid on.
Some people want the lid off just to make the intake louder, but I wouldn't want to sacrifice performance over noise.:simmadown:
