Re: Intake Routing
the factory setup is a cold air and you can open it up to work better with a K&N. Doing this and putting the filter in the engine bay to suck boiling hot air isn't a great plan unless you live in North Dakota...
Shorty on my car, my intake plenum would still be cold to touch after 1hr of sitting in traffic on a 90* day. That was filter sitting right behind the battery. The factory box sits almost on top of the rear exhaust manifold, with 2 almost 90* bends, combined with the 180* from the computer tube to the engine tube., I don't buy that the ambient air running a short ram is warmer than the air out of the factory intake.
My experience with both, especially in traffic, the short ram keeps the plenum cooler, which tells me the short ram pulls colder air than the factory intake.
