Is the fenderwell intake really that much better than one that sits in the engine. Kenne Bell says that engine ones can cause damage to the engine. Got to get a new intake so I don't know which one to get.
CAI kits really don't allow the engine to draw "cooler air". The air temp difference in the fender well vs. the engine bay is negligible. CAI kits really just less-restrictive intakes over stock.
I've never heard of the engine bay ones causing damage to the engine. Did they explain why?
The fenderwell one would draw cooler air is the only advantage I'd see.
I disagree. The temp under the hood from the engine and hedders has got to be warmer than the air coming into the fender well.

Heres a bit of info, take it as you will.
My last car was a 92 fox with a 351 high compression engine. It had an afm pms on it with the iat sensor re located to the c&l intake tube.
When I had the stock box (works just like a fenderwell cai kit, sucks air from fender) the avg intake temps were 75-80 (on a 70 degree day).
I later changed the upper elbow to one that fit under a stock hood and had to go back with a filter on the end of the maf b/c the angle was too much to fit it all back in right. My temps went to 120-130 at BEST. Got much hotter if I were in traffic while the factory box kept it cool at most all times.
Thats just my experience. Engine bay filters just offer too many oppurtunities to f chit up. Fan wash, more dirt/grease and heat are the obvious culprits.
the difference in iat temps from the c&l and the stock airbox was the fact that c&ls is aluminum and the stock is plastic and rubber. aluminum is gonna retain and transfer more heat than the plastic.
i made my own cai out of abs plastic and it stays cool all the time, it has a 45degree bend with the maf and the filter in the fenderwell. the plastic does not get hott and the filter is out of the engine bay. made a noticable difference from the chrome cai i had before.
Sounds like the K&N FIPK fits what you want. I have the kit and absolutely love it.
Whatever kit you get, stay away from those made of metal. I made the mistake of purchasing an MAC CAI (made of chrome) the first time around and I swear that I would have suffered 3rd degree burns if I had touched the thing.
