stillen is quieter than your popcharger

 

in order from loudest to quietest..hope this helps

ztube + popcharger
ztube + stillen
ztube + k&n panel
gtube + stock filter

either way, you wont really get much performance gains from this. none that youll really be able to feel anyway

and of these combinations are purely for sound most of the time

 

haha as most are with this mod

IMO stay with the p/c

some say it has heating issues but IMHO thats only when youre idling

once you smart moving again youll flow cooler air and itll be fine

 

Popcharger and Stillen sound identical to me.... during rev and while driving.

And the short ram intakes like the popcharger and Stillen should actually produce better results from the CAI. The air flow through the engine bay while driving is very efficient, and the heatsheild from the popcharger and especially the Stillen box really make a difference. Also the shorter piping should have a better throttle response. In theory, the a short ram with an effecient heat sheild will out perform any long piping cold air induction intake system. But no one is really going feel the difference from a pony or two from a 300hp car

 

^^yeh i forgot to mention i would say stillen and p/c are very similary but still IMHO p/c is a tad bit louder

like Silverbolt said you wont feel the difference..

so i say stick with p/c since it is louder/equal to stillen in sound and will produce more power "in theory" even though you wont feel it lol but the thought makes you feel better hahaha

 

And if you want that mean aggressive look, get the popcharger. If you want an OEM stealthy look... then get stillen

 

if you already have it dont bother switching it out.........its all really the same thing, jst CAI is a little louder

 

I really like the mods I made with the Stillen CAI
and the Z-Tube......then adding the MotorDyne
1/2" spacer didn't hurt either.....more mods..more
mods.....more m

 

1/2"...5/16"

it all depends on whether or not you wanna keep the engine cover aka keep this mod stealth

engine cover wont fit with 1/2" to my knowledge..unless you modify it maybe?

 

5/16 for a street car. 1/2 for a track car. The 5/16 has a nice even little increase through out... where as the 1/2 suffers a loss at the bottom, and has to wait towards the end to pick up alot of its gains. Granted, the 1/2 has more hp increase... but its not just about how much... its also about where, and what are the trade offs
