How much hp will a street flow air intake system add to my engine i have a 1.5 liter 4 cyl. engine the number is D15B7 its a 102 hp right now i don't know if thats to the wheels though

 

lol, top end probably about 3-7, but still anything helps.. i say go for it.

 

You'll probably gain a few ponies. Not too much, not like 12 like some people advertise on ebay. I'd say 3-5 tops. But, the intake really helps the engine breathe better and definetly helps the car drive smoother, along with throttle response. In my opinion you shouldn't look at it as a big power boost, just something to help the engine breathe better. But, that's just my .02.

 

^+1 I agree... not near as much hp as ebay promises... my 04 civic loves it... I was more into the sound than anything else... there was better response but mainly I got my money's worth because it just sounded fierce
