sentra intakes...i need opinions

[sentrastace]

so whats better....a stillen hi flow intake, or a fujita cold air intake? those are currently the only ones out for the sentra 2.0's and i'm having trouble choosing. can anyone give me the advantages/disadvantages, which one is better for gains, which one sounds better or anything? does anyone actually have one of them? Thanks

I dunno about CAIs other than it takes abit longer to install than a SRI. I personally like the SRI because its easier to get to the filter. The Stillen CAI takes the air from infront of the wheel well, so it made me think about water, rain, floods. The SRI is high enough for me no to worry about things like that. Anyways, the SRI that I just ordered a Weapon-R SRI for my 2.0s. Let see if it exceed my expectations.

This has been discussed before, but here's the skinny:

CAI's offer more power overall. The gains in terms of throttle response aren't as noticeable as an SRI, but the net result is still more power. Thus, performance-wise, a CAI is the best bet.

People who are paranoid about sinking their car in a puddle with a CAI aren't thinking straight. Because water is more dense than air, you would have to submerge the ENTIRE filter element/intake point to actually pull in enough water to damage your engine. Unless your car is slammed to the ground, the likelihood of that is practically nil short of driving through a lake or a 100-year flood. I've had my CAI for nearly 5 years and driven through some large puddles and moderate flooding during a hurricane. I've never once had an issue with taking in water. Oh, and I'm on a ~1.5in+ drop, too.

The advantages of an SRI are a tiny bit more noticeable throttle response increase (again, either way you're getting better throttle response than stock, but the fact that there's less piping means the SRI feels like it's pulling sooner, even though in terms of power it's not doing any better than a CAI) and the fact that they're cheaper than CAI's.

I'm using bold for emphasis because a lot of people mistakenly claim that SRI's make more power at low rpm/initial throttle tip-in. The reason for this is because SRI's get louder sooner than CAI's when you get on the throttle, again because of the shorter piping, thus creating the illusion that you're making more power at that moment than the CAI.

[sentrastace]

that was ridiculously helpful, thanks so much!

[DarkAquarius]

That is a good comparison. No parranoid, but ideas about those who might live in a flooding area... Anywho... Nametakennow has the right diff on it.

[djoxide]

ebay is the same as the other big names, its all the same piping, just get a decent (k&n) filter and you're good to go.

I just got a CAI from Injen - took a while to install (had to take off the whole front bumper) it but it was a really nice kit. Came when several rubber padded mounting brackets and built in MAF holder. Over all quality was top notch, all in all a really nice kit if you don't mind spending the extra money.

Nametakennow, always gives some of the best info, but anyways personal story with water.

I have a short ram intake and it was a massive storm so I drove home from school and parked into my garage. I noticed my hood was popped open a bit. I didn't touch my hood in a bit so i opened it and it was soaked. My air filter and all. I just switched air filters and thankfully no electrical damage. Moral of the story, the air filter can take a wetting.

If you are paranoid K&N and other top brands have this water shield that goes over your filter.. And AEM has a bypass valve so if you filter does get clogged.... So there are options to give you a peace of mind.

actually, most people dont know but some water into the intake is a good thing. Water injection FTW.

Either way though, i perfer the SRI. Ease of installation, piece of mind, and i usually mod for low end torque, then high end power.

A VERY tiny amount of water, usually 50/50 mixed with alcohol, yes. However, that by no means means that anyone should wet their filter and head to the races.

The SRI doesn't actually make more low-end torque. It has a flatter powerband and makes more noise initially, so it gives the impression of having more torque.

[djtorello]

true, but my powerband is already flat. Gotta love CVT's.

[nametakennow]

The trans doesn't change the engine's powerband, it changes how it's used. Regardless of transmission, you'd be making more power and more torque with a CAI.

Actually, why would you "mod for low end torque" with a CVT anyway? Your trans is going to put you in the fat spot when you floor it no matter what you do.

[jason51873]

If you scroll up I stated that I installed a CAI. Now after driving with it for a few days I am really happy with it. I have had SRI's in the past and I have to say that I like the cold air better.

I did notice that I did loose a little spunk right out the gate, but the increase a few seconds later is really noticeable. Over all it seems like the CAI is a little more performance.

Speaking of CVT's and intakes, does anyone have audio clips of their intakes (CAI / SRI) on a CVT? I've been curious as to what they sound like.
