I never really examined the intake system until today.
I don't understand how I would "gut" my airbox, since there is nothing inside of it. There is a pipe leading to the airbox, then the filter, and a hose to the TB. Ya there are those little reservoirs hanging off of it for some acoustic tuning, probably.
So at the risk of being controversial, I don't see that much wrong with the stock intake setup. It pulls air from behind the headlamp, just like you want. The filter has a lot of area for airflow.... and you could put in a K&N.
So where is the problem.... hmm well the actual intake area is not huge, but GM could have made it bigger.. but they didn't for some reason. Maybe they didn't need to? The hose going to the TB is a corrugated style, so yes it isn't perfectly smooth, but the engine needs to move.
I am wondering if half the performance gain of these intakes is the sound level.
Yes, I am posting this to get a response, and no I am not trying to insult anyone.
Oh, I also took at look at the MAF filter. I can see where that would be a restriction point. I also think that mine could use a good cleaning, it looked like it had some buildup of "stuff" on the inside edges of the holes. Not a lot, but something. I will have to take it out and clean it up.
