Re: intake
I've been driving on it for well over a year.. through some really rainy seasons.. and have absolutely no trouble.. even some where I submarined it and the thought crossed through my head, but no problems at all.
I'm sure they do that just as a disclaimer, which EVERY part manufacturer does.. list it as "off-road" use.
The filter location is well housed within the fender, but it is more accessible than the stock location, but that adds to pulling colder air.
Common sense prevails in any situation, drive smart, and you should have no problems.
