Rev up Airbox vs other intakes?
Rev up Airbox vs other intakes?
Sorry if this has been asked before (don't flame me 
), but after searching I haven't been able to find the answer I want yet. 
I can't decide whether to buy a K&N Filter and Rev Up airbox or get an aftermarket intake... I was looking at the Stillen one (because it has an airbox unlike the JWT) or the R2C (which looks to be the best but I haven't heard too much about it).
Will any of the aftermarket ones make me lose any power or make the car sluggish in the lower RPMs? From what I understand, the new airbox cover will give me a little bit more power in the lower RPMs (probably not noticeable) and a deeper sound. How does this compare to the Stillen/R2C?

The aftermarket intakes that lose power are the ones that are a short ram and have heat soak.
Honestly, I think the revup airbox is very slightly better, if at all. Not worth what you would pay.
I have the stillen intake but I'm using a JWT pop charger. The jwt heat shield doesn't block enough heat plus the venturi ring on it is metal and isn't shielded. The stillen air box is the next best thing to the stock airbox. I wrapped mine with some heat shield tape and my intake air temps are right about where stock intake temps are. Much better air volume though.

(Sorry for all the questions
)
if i were you and you are not concerned with it looks shiny. i would just get a drop in knn filter and keep the stock airbox and get a ztube. none of the aftermarket set ups are going to do any better than the knn drop in. save yourself lots of money

Can anybody else comment on the R2C or Stillen intake?
Don't worry about his opinion. He is almost always wrong and this is no exception.
Heat soak is a killer. JWT uses a metal heat shield (conducts heat) and a metal velocity stack. Both will conduct heat and cause the dreaded heat soak. You just need to find a better way to shield from heat. Queue the HEAT SHIELD TAPE that I use. Think about it.
You won't lose power with the JWT but most people with the Injen do.
Long tube CAI (not short ram) lose throttle response and it has been proven that air 0-18" off the ground is normally higher in temp than 18-36"

I'll just add that most of the quickest and fastest NA Gs and Zs run the OEM and Revup airboxes. They are not restrictions. I absolutely love the Revup airbox. The sound and driveability are worth the $90 price.
As for "shielding heat", it's not going to do much. The issue is heated air in the engine compartment. You can shield from radient heat, but all the shields in the world won't help the fact that the underhood temps are 120+ degrees at a stop or slow roll.
