I need some advice on some Cool Air Intakes for a 2005 Civic Si?
Any suggestions

where to buy, ebay,
install, take off bumper
take of ugly black intake and remove o2 sensor and vaccuum tube,
put in new intake
replace o2 sensor and new vaccuum tube. voila 1-7 hp

Yes k20 motors perform best with
Injen Intakes. Look online for that brand name.

What about the AEM V2 cold air intake, is it better than Injen's?
And is it worth paying the extra money for the V2 then a regular AEM cold air, or is it just paying more for the sound?

AEM V2's do not perform much better than the regular AEM CAI. Go with the Injen if you want a little boost in power.

Nother question, about the exhaust system on the Si, which should i get? And what size car speakers are in the Si.

I was thinking of going with DCspots's catback exhaust system, but is there better out there?

They all do basically the same thing, but may sound different. I have to say the Invidia full cat exhaust system is the best performance wise and sound wise that I have come accress ( check for this part number INV-HS02HC3GTP ). I have this on my EX as well as a Type R teg. I dont recommend the Greddy EVO2. I have heard good things about the DC SCS system, but have not experienced it first hand. Now to finish your project get a header DC 4-2-1 Ceramic.

I was at the Injen website, and looking at the intakes like producepetesi advised me to.
Would it be wise to go with the RS? or do I not really need that and can stick with the RD?

Thanks again for all the guys helping me out

Also having problems finding parts for an 05 Si, i've sorta come to an assumption that all 03-04 parts will fit the 05, how far back can the part year go for it to fit on an 05? Cause i see no difference in the engine. For example that header you recommended only could find it for an 00 Si..i'll keep searching though

99-00 si has a completely different motor.

Yes 02+ SI HB parts fit 05 models and the DC header is there 335$ .

Thanks, that will help alot of searching and strenous work when im trying cause i would be trying to put an 00 part on an 05 :-P
And wtf the header i found on DC was 725 lol, but that was off their main website, prbly find it cheaper somewhere else no?

Froogle it :bigthumb:

Does anyone effin know the speaker size's of the 2005 Civic Si! god i can't find it anywhere lol.

I know im annoying ya guys, but I just don't wana fuck my car up and I want the good equipment.

Now for the Clutch, im thinking ATC or clutchmasters Stage 2, any expert hints by all you awesome people ;).

That ya told me to get.

And also if i would replace the cat as well, think i'd pass emmissions. I sorta got an idea of putting a bypass valve on the exhaust before the cat so when emmissions come up i can switch to the cat, and when im done, switch to no cat :-P

Does anyone effin know the speaker size's of the 2005 Civic Si! god i can't find it anywhere lol.
check www.crutchfield.com just never order from them overpriced bastards.

Just get an aftermarket cat, which will pass emissions with out a problem. Mines getting ripped off when the turbo is complete.

-What I think you should do is buy some nice Recaro seats for your vic and sell me you stock ones :evillol:

My bros got a v2 on his 02 si, and it sounds damn good, i noticed a difference in performance as well, and if you live where you get a lot of rain in, you dont have to worry about sucking in any water ,because it doesnt extend as far as a cold air but produces about the same power gains.

front speaker hole: 5 1/4" hole, rear 6 x 9 type A

I already blew out a stock speaker in my 04 Si bought in Sept. oops, to much Lincoln Park.

err linkin park

these for example will fit..... oh and this site tells you what will or wont fit..... http://www.cardomain.com/item/POLMMC525?vq_id=none

Good deal, I already bought some 5 1/4 and 6x9 Rockford Fosgates for my 1996 Honda Accord V6, and i took em out before i sold it. So im glad i don't have to re-buy new speakers ha
