Which intake? 07 si

[Mattzilla]

OK first off I'd like to say that my #1 priorities are:

-No hacking my new car up
-No problems like rough idle, hesitation, CEL

Secondary priorities are sound and performance...

So which intake do you guys recommend?

Thanks in advance,
Matt

if you don't want to 'hack' your new car up then you are looking for a SRI. With a CAI you will have to cut the fenderwell, which is nothing major. Some people actually got CAIs in w/o cutting. in the SRI a few good ones are Inje, AEM, and Fujita.

My first suggestion would be an Injen SRI since you don't want to hack up your new car supposedly. I have an Injen CAI and I didn't need to cut the fender and I have no rubbing issues at all.

You are going to get the highest gains by getting a CAI. It makes the engine sound a lot more throaty if you get the CAI. Other members have good reviews on the fujita SRI as well if you choose to go SRI.

Go with Injen CAI, no major cutting or anything, like reaper said some fit in without...It gives the best gains, and sounds great!

[Mattzilla]

OK and the bumper needs to come off for both SRI and CAI, correct?

Also, has anyone had issues w/CEL or rough idle or anything of that nature with the Injen CAI?

Bumper for the CAI. The SR is pretty easy install.

No issues with my Injen SR

Just installed the Injen CAI yesterday and it is awesome. I cut inside the fender (very small amount), but I know I could have done it without the cutting.

Sounds great, no CELs/hesitation and I've noticed a slight power increase. I'm very happy with it. The car sounds like a monster now at WOT past 5k rpms.

Definitely easier to take the bumber cover off. I didn't for my Injen CAI but it's a PITA. I didn't realize how easy the cover comes off until installing my fogs.

Everyone's mentioning Injen this, Injen that. Consider K&N; it comes with a heat shield, unlike Injen. If you don't like the oiled-filter, swap it out for a dry AEM or Secret Weapon.

personally, i would go with the AEM CAI (if the CEL goes on, that means you didnt install it properly) over the INJEN CAI (the CEL doesnt go on at all after installation)

i agree with SI_CIVIC...but i would go with the AEM CAI and K&N FILTER combo.

Injen CAI all the mother beeping way. Sick, deep roar at WOT and NEVER EVER EVER a CEL like the sack of **** AEM product. Buy the K&N if you wanna suck up tons of hot air. If you want a great pronounced engine roar, but also want the best possible performance you SHOULD buy the INJEN CAI. Just do it man, you will not be disappointed. IF you do buy the AEM, I'll drive by with shaking my head with my Injen roaring while you're in your garage trying to turn off the CEL.

This post boggles my mind.

[reaper702]

no need to take off the bumper for a SRI, but you do for a CAI.

btw injen > aem!!

[UncleSid]

INJEN FTW!!!!!!

[imtim25]

combustion engines work like this:gases mixes with cold air to for a mixture(the fuel air mixture) that is ignited by the spark plug in the combustion chamber and it psuhes the pistons up and down which makes the car run. what the intake does is it pushes more cooler air into the combustion chamber.

if the intake, such as Injen's CAI, is installed and there is no CEL...how would you know if it is installed correctly or if it isnt if the flow sensor isnt turning the CEL on in any situation. that means i could just install the Injen CAI by just reading the instructions (hell that means i could even skip some steps) and end up thinking that i installed it correctly just because the CEL doesnt come up and my car is roaring.

i like the aem cai becuase if the CEL comes up, that means something is wrong and i installed it half-assed and i need to fix it to get reach maximum efficiency.

this is my 2 cents but i would just go with the AEM.

never the less, i recommend the K&N filter for any cai's.






FLAME ON!
(i know it coming)

OK, well that explains your logic behind the statement and makes sense. But, I think its the design of the intake that is making the CEL come on, not how people are installing them. Thats the point here. It's not like the Injen "CAN'T" get a CEL. If you had leaks or improper installation on the Injen intake you would know because of the sounds, performance, and yes a CEL would come on. If I installed the Injen intake with a blindfold on and then purposely didn't tighten the seals and stuff it would be messed up just like the AEM would if you did the same thing. BUT, the AEM is being installed right and still has CEL issues (with some people at least). Also, Its proven that the AEM doesnt make as much power as Injen. People have put up dynos of the Injen CAI gaining as much as 13 horses. The AEM one is 7.3 on their website. Given that, plus the CEL issues, plus the fact that there race header falls apart, I don't know how in the world anyone would buy an AEM intake. Why would you do that? I just don't know. No flaming here......I understand your thinking and you have a point, I just don't think thats the problem. Anyone else?

You will if you want to fully remove your stock intake unless you somehow get that huge lower resonator box out from the battery section. I'm not sure if it can be removed from the fender though.

[imtim25]

i realize the gains a long time ago but i'm just playing it safe.
if i cared about the gains more than my engine, i would just experiment and create my own CAI like some people do.

its all up to the owner on what they're going to buy for their car but again..this is just my 2 cents and i'm glad that you understand where im coming from.

SI's arent Civic's...dont treat them like one. <--my new slogan

If run for a long time, there will actually be hotter air entering into the combustion chamber then from the stock airbox because of the heat within the engine bay and the metal intakes like AEM's, Injen's, Fujita's etc. For the AEM part just because you have a cel doesn't necessarily mean you installed it wrong, but because of the rushed development on AEM's part and the poor design of the intake tube.

ah yes, forgot that bottom part of the resonator box
