So many intake options!!! :(

1013mm · 05-16-2011, 02:56 PM

Should I just leave it alone

?

BSM 135i · 05-16-2011, 03:16 PM

just buy a drop in a call it a day. these kind of threads lead to nowhere, you won't get an answer. i have an aFe intake but currently running stock.

esscolab · 05-16-2011, 03:17 PM

One answer...

YES

Leve it the fuck alone, they muck sod all differnce

ErvGotti · 05-16-2011, 03:43 PM

Leave it stock unless you plan on boosting more than 14psi. Anything less and the stock intake is more than adequate.

Tough choice. Dinan and GruppeM are the best looking, but DCIs make cooler sounds.

As for function, DCIs are good for drag racing and don't cost very much; and Dinan is good for everything, but it's expensive.

i measured a loss of 5hp with dci's on the dyno

bogart · 05-19-2011, 04:02 PM

the sound is well worth it!!! i know you have the N54, but i just installed the Injen intake on my N55, and it is awesome. You can hear the turbo spool and the DV release pressure.

pixelblue · 05-19-2011, 04:04 PM

that gruppeM looks sweet. too bad it costs an arm and a leg

MikeVictor · 05-19-2011, 05:22 PM

I think there's a thread on e90post somewhere with some comparisons on drop-filters (and possible DCI's) to stock. Not a great deal of difference unless you're running much higher boost levels as ErvGotti pointed out.

infinitekidM2C · 05-19-2011, 05:41 PM

Not much difference between the two; i felt better throttle response with my dci

M3Newbie88 · 05-19-2011, 06:09 PM

Trust me you might as well leave it.. i have 4 different ones..

DCI
SCI
RR
AFE

LOL... dont even know what they all do but just switch them up.. might as well start selling a few of these and keep one on lol..

mineo77 · 05-19-2011, 06:21 PM

get a drop in and leave it alone, even if you boost more than 14psi all the DCI will do is suck your power away (along with a shit ton of hot air).

infinitekidM2C · 05-19-2011, 06:32 PM

here's my setup...at the quarter mile track i did a couple runs and got better times with the dci but you know how unreliable track times are...i switched back and forth and like the modded intake best.

I had been planning on doing this same comparison. Do you have the Cobb logs between the runs?

Eyeman · 05-19-2011, 07:12 PM

Injen seemed the best choice to me.

Was that while stock, or modded?

escobar929 · 05-20-2011, 09:40 AM

so many options, so many threads on the same subject

Dmacc · 05-20-2011, 11:47 AM

If you get a tune, and boost high psi, DCI all the way. Just get the ones from burger, they're like $95

Did your trap speeds increase? Thats a good indication if you actually made more power.
