Its been cold as h*** here lately but I've taken a look at the intake and yes it is similar to a cold air setup, this leads me to think that something of an air charger might be best, it reduces/eliminates the restriction of sucking up air trough a path, and would probably take in slightly warmer air being as it sits open in the engine bay. However with this idea I've also noticed that my engine has a (i guess i'll call it a hole but it comes out to a hole) hole on the top of the one side of the exhaust manifold which has a metal hose attaching it to the bottom of the stock air intake. This leads be to believe it is somewhat of a WAI, what would I be required to do to that if i put an air charger on the vehicle.

It also seems like a lot of people are recommending changing the belt driven parts such as the cooling fan and the water pump, with with electric ones. I was wondering if anyone had done this and would have recommendations for installation, as these all seem to have 100% support. I was also wondering if a more efficient or more powerful alternator would be a good idea if I'm changing more parts to be electric?
