Cold air intake vs Forced Induction
I have been researching for days and I am totally confused.
I am trying to figure out what is better. A cold air intake, which still goes through to a panel filter (like Autodelta one). Or an induction kit.
What confuses me, about ramming a massive K&N filter, or pipercross filter in your engine bay, is the engine heat.
SURE, the sound of this type of induction will be great. But when I stop the car and open the hood it's HOT under there, very hot. Surely sucking in hot air is BAD for your engine (let alone performance), there just is NO cold air near the engine bay, especially when at stand still at the lights. BUT, why is it that some of the fastest performance cars I see in magazines always have massive K&N filters under the bonnet? Also, with rally cars, which go through very dusty conditions, they all have massive K&N or Green filter pods next to their engines too. Surely if it's good for rally, in heat and dust it must nean it works?
I am truly confused! Any help appreciated. LOL.
