Intake flow will only be as great as what the exhaust will allow. I have a DE with the Injen CAI and I could hear it with the OEM exhaust. Now I've installed an Agency Power and dayum! Combined these two things make my Z SCREAM like a banshee!

 

Neither.

JWT Popcharger has shown the best gains for the DE (what i have) and suprise! Its the cheapest.

 

Some intakes have even shown loses. The AEM and Nismo are the worst i believe.

The only 2 good things to do to the DE's intake is either a popcharger, or switch your intake box with that of the 06-08 and throw in a K&N filter. Any other intake is a waste of money imho.

 

how much power would i get from the popcharger compared the to stillen? this is a really hard choice for me. since i keep hearing diff things. can anyone help me out.

 

lol i know im right. i have these intakes and when they where the only mod on my car at the time i was dissapointed about the lack of sound. Even at WOT in the cabin you wont hear it.

 

My HRs Injen CAI start growling at about 4500 rpm. Its much louder than stock.

 

Actually the injens use dry filters. Not sure if the OP is running something else, but that's what came with mine.

They are blue, if you search the DIY installs, there are a few pics of them.

I noticed a big change in sound when I installed mine.. much more throaty than stock intake. The real growl comes from the HFC's + Bassani combo or equiv.

 

Not sure, exactly...i would try and search on here for that.

Just believe me when i tell you to either get the popcharger, or a 06+ airbox with drop in K&N filter.

I think Z magazine did a comparison of all the intakes, and the popcharger won with the most gains. AEM, Injen, Nismo, Fujita, etc are all a waste of money.

You must understand, cold air intakes are not always better. The further the air has to flow through a tube the weaker the suction is at the filter, thereby the less air the intake is sucking in. Thats why they have short-rams.

You want to find the perfect balance between the shortest length of tube, and best placement of filter/box to bring in cold air....pref as far away from the hot air the engine is heating up as possible. The stock length of tube is the perfect length.

 

my jwt does make a growl but I can't hear it anymore over the injen cat back and test pipes

 

injen has joined with amsoil and now come with blue dry filters..i up graded from my oil filter to a new amsoil/injen filter (on my DE cia)..supposed to be better??
