Do you fellers prefer your intake element in the fender or in the engine bay? Why or why not?

Before the supercharger, i was running the stock airbox (my engine is completely stock though). With the supercharger, it comes with its own air filter assembly that keeps it in the engine bay but has a cover to protect it from heat and air turbulence. Eventually i want to do a powerpipe to move the filter to the fender, but may not due to CARB/SMOG issues.

CAI in the inner fender. Colder air and cleaned up the engine bay.

Mine is in the fender as well. Just been noticing it in engine bay on quite a few cars lately. I would think it would just eat hot air under hood like that.

K&N Filter in fenderwell via home built intake. Keeps the intake charge nice and cool. The stock setup does a very good job of this as well.

The stock airbox setup is actually very good and was not a limiting factor at my power levels. I swapped to this setup simply to clean up the engine bay.

From my experiences with a speed density setup, if you're making under 300whp the stock intake w/o silencer isn't holding you back or costing you any hp.

I've dyno'd this car with both setups.

Stock air box here to with no silencer that was my very first mod and put a k&N filter inside so it breathes better.

0-1 below 5k rpm, 3 at 5500. Essentially nothing, within margin of error.

If you're interested in a CAI, I have a Densecharger one that I had to remove due to no CARB cert here in California. Nothing wrong with it, but bought a BBK one so as it passed smog. As all say, engine bay gets to hot.

I put a “through-the-fender” intake kit on my ‘86, but later removed it and used the stock air box with the silencer removed and a K&N panel filter. This brings cool air in from inside the fender well.

Stock air box (which pulls air from the fender not the bay) or in the fender filter kit. Otherwise you don't have a cold air kit, you have a hot air kit.

... Or you do a functional hood scoop ...

It's amazing how many people install a 'cold air kit' that has the air filter exposed inches from the exhaust manifold/header. They have no idea what they've done.

That was my train of thought when I started this thread.
