Whats more effective about spending a pile of money for a mass produced piece of plastic that does the same exact thing he already has?
That is very subjective. I think the SRI looks way better than a NPG CAI. To me, aftermarket CAI says "I like throwing money away".
Now, the heat shields, THOSE look ghetto. Trash cans? Pipe insulation? Really? Your telling him what he has looks ghetto and suggesting a trash can in the same conversation?
There is absolutely nothing wrong with what you have right now. Unless you dont like the appearance, dont worry about it.
A factory SVT intake is a good option if you want to restore a factory look without wasting a bunch of money.
The NPG CAI gets all the glory as the "best available", but realize that our stock intakes are already cold air intakes, and perform just as well with a high flow filter installed. That SRI you already have, although it sucks relatively warm air from the engine bay instead of the fender, will still perform just fine for as long as you want it to.
One question though, where is your IAT? It looks like there is a hole on top of your filter adapter for the temp sensor, but there is nothing there. Does it tap in on the side where we cant see it in the photo? If that really is an unused hole on top, you should fill it or cover it to prevent anything getting sucked in unfiltered.
