Which would give more of a horsepower gain, the JWT Pop Charger (6.5 rwhp independent of Z Tube) & Z-Tube or this Stillen intake w/ Z Tube? It lists the intake alone as producing an extra 11 horsepower independent of the z-tube. I just dont know if that's rwhp, or flywheel... :/ anyone help me out please?

The Stillen Hi-Flow intake listed here:

If you are set on buying one, the stillen gets the nod. But none of them really give the hp as advertised.

 

well what I want to do is get the Z-Tube, the cold air intake, and the motordyne 1/2" plenum spacer. Do u think the 1/2" spacer will outperform the 5/16" spacer? It states that it's supposed to

 

go on their website and examine the dyno charts. decide for yourself,

Get the stillen high flow intake, it has a better heat shield

 

do some more research here on the forums.

Seems all you want is power and only looking for HP number only.

 

You won't feel those extra horsies, It's more like adding 10 lame horses to your car, could potentially slow you down.

 

Stillen cause it looks nicer!!! neither one you will feel the difference!

 

So even if i gain horsepower on the dyno charts like they show, it won't help at all? I'm planning on getting aftermarket headers and test pipes with a friend building me a custom straight pipe exhaust system in addition to the intake, z tube, and plenum spacer. All of that together won't raise my horsepower?

 

yes, yes, maybe, not really, not really and yes

 

^^ LOL

Intakes aren't going to net you much but noise gains. If you're going to go with one the Stillen is the most OEM looking box/heat shield.

 

well even if it's not much, it's still something, & I dont have the money to twin turbo my car like i'd want to... =/ I'd also like to get the aps single turbo system even if i didnt get the greddy twin turbo. But sadly both of those are just too much for me... it sucks. I have to stick with cheap mods.

 

Injen Cold Air Intake RAWR

 

save the cash, dont get an intake go another route. when all your mods are complete then get the intake; my opinion

 

05+ use the stock airbox with a K+N drop in. Lots of threads on this.
