I bought and installed the SRI from Injen and it there was a difference from before. Couple that with an exhaust and it's much more better than stock.

Oh yeah, and you will hear some sound and as your rpm's rise, the sound will get louder but not too loud.

 

k im coming out. SRI's will give you more power because they breathe a lot easier than the stock box. if you take apart the stock box, you realize that the entire inside is a big filter. because of that, its very restrictive. the SRI gives you more power because its less restrictive. but i still swear by CAI's :P

 

Holy crap! Nails had a breakthrough!

Congrats, big guy. Are you feeling fragile now? Do you need a hug?

 

I feel a group hug coming!

 

a CAI will give more overall HP, but as for better useable power... im all about the SRI. Plus they sound way better than cold airs do. Also, the HP gain of a CAI over a SRI is about 2hp at best on a civic.

 

a man can get confused on CAI or SRI

 

CAI has the laws of physics backing it up

 

I'm totally confused now........so, what's better, stock air box or Iridium spark plugs? LOL
