septa New Member 7 Member For: 11y 9m 7d Posted 29/01/14 05:39 AM Share Posted 29/01/14 05:39 AM Just a few quick questions, was about to spend some cash on a cai but after reading a few posts I can see the idea of cutting a hole in the standard box seems more the go. Its free so why the hell waste cash. Just wondering wats the downside? Im assuming u dont get the small power gain u do from a cai? Do u still get a bit of extra sound? I guess I want a cai coz its a cheap n easy diy project but if its a waste of cash I'll leave it Link to comment Share on other sites More sharing options...

As u have read the cross over and piping is the restriction not the box so save your money for now and spend on a better cooler or exhaust . Downside is not much really. Will sound a little bit louder Link to comment Share on other sites More sharing options...

Only closer to 375-400rwkw I think I'd want mine gone. Anyone been at those power levels, changed only that and seen the gains? Link to comment Share on other sites More sharing options...

This was my airbox that I hacked up Last week fitted plazmaman turbo side intake , worth the $700 just for the noise it makes, haha still makes me giggle everytime I give it some. I also like the look of the engine bay after getting rid of that fat ugly crossover Edited 29/01/14 12:16 PM by sct911 Link to comment Share on other sites More sharing options...

Looks plain without it Unless you have a Nizpro plenum with the writing back on it! Link to comment Share on other sites More sharing options...
