intake sounds messed.

[sackerius]

yo, i got my intake on today, and it doesnt have that 'intake' sound... i have a feeling its the D.P.I. injection on my car.... its a ractive air intake... also i have straight pipes that end at the cat lol and my car is very loud.. so i just might not be able to hear it.. or what?.... gimmie some experiece u guys have had... thanks.

I had an intake on the little 1.5L motor before I swapped it out. It didn't have the intake sound either. I think it has to do with the convoluted intake tract near the throttle body. Plus you not might be able to hear it if you are running a straight pipe.

Ok, little known fact on DPFi intakes. Take off the covering that says DPFI and remove the brass plate that is inside the box. i think this was an emissions trick to reduce power. I did it and the intake sounded better.

I have a 1.5 dpi motor and the intake sound is great on my car. I dodnt have to take that brass piece off, im not really sure about that mod. I have heard people say it's not a good one to do.

hey i have a 1.5 dx and i put intake and it sounds good. im going to take the brass piece inside while i wait to save some more money to buy my si intake.

mine only has the intake sound when I am really flooring it and under about 3 rpms, after that the exhaust takes over. I might just put the stock box back on and sell the thing, cause I hear the stock box blocks dirt and water and stuff better. But the car seems peppier with this in. I bet I would be able to hear the intake better if I had stock exhaust

my friend has a 97 hb i love that engine set up, he bought a k&n and took off the air box because those engines the throtlebody is like facing up i guess and the filter is right there and he can take off his air box, it sounds tight as hell, i know it has nothing to do with this but..........

k yo, if i take that litle piece out, the brass piece... will it wreck anything?, i really dont want to fuck my car over becuz i dont have $$ to fix shit right now... plz emphisize on some stuff thanks.

Take off the top of the box and look inside. it is empty except fo a brass plate that blocks the airfolw. I have had mine out for six months and my car stills perfect. All that piece does is block the airflow instead of giving a unintreputed path to the TB

Hey guys, i took off the little brass piece like a year ago on my DX, and i havent had any problem with it, and i have an Si now, and i only have a AEM CAI on and its fricken loud! My car sounds like a Harley under the brige at High RPM's! Its Fukin SWEET! i can't wait untill i get my Exhaust, then it will sound 10X cooler!!!! I wanna get a nice quiet one though, i have already had a Type-R-ICE car, now i am gonna have a Type-S-LEEPER car and get an Apexi World Sport cause its Low Profile and its a quiet exhaust and its CatBack!

Speaking of DPFI.... is the DX and under the only engine that has that little round box on top of the TB? Are all of the ZC's MPFI without that box?

The DX/LX are the only ones with dpfi. The ZC DOHC is mpfi.

Yes, the ZC is MPFI and has the same throttle body as an Si...The DX (and LX if it is a sedan) has the d15b2 with DPFI.

Back to turbcivic's plate thingie..I have also heard about it being a bad idea to take out the little plate...I have a DX with a CAI and mine doesn't have the cool sound either...but I sure hope my ZC does!!
