which intake is more efficient and louder?

 

Injen, but it's only been discussed about 4 thousands times already

 

+1 (lock it down)

 

+2


P.S INJEN FTMFW!

 

And "louder"? There's a good reason to get an intake...

 

My Injen gives it a throaty growl when its hits WOT at 3k til redline, at about 3.5k the hoover vacuum turns on ;) Love that sound! Oh, dynos show Injen giving more hp and trq but they are all the same, just Injen is 3" piping and R&D so the MAF sensor wont tell the difference from the stock intake to it "supposedly"...not sure if i buy it but oh well.

 

injen, i have a injen intake and its nice, the vacuum sounds great the whistle is awesome!!

 

Injen FTW. I seriously think this is the most posted topic on SL...

 

Ha... no way.

"will this void my warranty?" I think would spank the "which intake?" topic.
