Best intake sound/performance 3.5 SE

[striklybidnis]

Any thoughts? Or are they too comparable to see a difference?

Figured this was a good place to start modding my 3.5. Cheap, something I can do myself in little time, noticeable difference in sound (and power?).

Thanks.

Big difference in sound, my butt dyno says its faster, but I know thats not the case, Blake says his car was slower with his injen intake. I have the fujita, and love it.

[striklybidnis]

damn that was fast...thanks brother!

i'm just going to wait for the K&N

[Alt.ImaCoupe]

I installed the AEM. Sounds nice and feels a bit quicker.

I have the Fujita and I love it. It just roars once it gets to 4k. Got a10whp and 14ft/lbs gain at the wheels on before and after. Check out the dealer locater at http://www.f5air.com you should be able to find one close to you. Or E-bay it...

or you can order it from their website with free shipping.

Will the Fujita work with a manual transmission? Most of the intakes I've searched for state that they only work with the auto's.

[mcheddadi]

yep, it will

[EMAN44]

Good deal, that means I know what intake I'm gonna get

Addidas, u still ahve ur injen intake? sell it to me, il dyno the difference between stock, fujita, and injen lol not evne sure if the numbers will show up significantly enough since intakes give like what 2-3 hp gains?

[RobPaulson]

I swear it was

i just installed mine, my butt dyno says my power gain was over 9000

[08whitecoupe]

I just got a stillen hi-flow intake and it came with a k&n filter.it's got a growl to it at about 5000 rpm and you feel the power.u also get better mpg not much 1-2 better.I was gonna wait for the k&n but the stillen is the same thing.it took about 20 min to install and it was $250 from stillen.

part # 402841- thats for the 3.5 coupe .

[Dexion]

To each his own, however for me there was definitely an increase in power over the stock intake. I switched back to stock for a week and I can tell the difference in acceleration easily.

This is my first post on the forum. I purchased a 2012 3.5 RS Coupe a couple weeks ago and actually ordered the Nismo Cat-back exhaust that Nissan listed in their brochure. As it turns out, the exhaust is not available for the coupe - Nissan's bad. I will be selecting an alternate system (there is some great info available on this forum for exhaust systems) but the purpose for my post concerns the Fujita intakes. Their web page is not very user friendly when it comes to contact information. I would like to touch base with them and find out if anything is available for my application. Those are the two mods that I would like to make initially (exhaust and intake) if I can get some information. The 2011 and 2012 may be similar enough to be used laterally IDK. If you guys have any further information please pass it to me.

Further, I just spoke with the Dealership and will likely be purchasing the Borla exhaust system (if it is available as a cat-back kit). I don't know how beneficial the axle-back kit will be for HP increases. That would likely fit better under an exhaust topic...lol

Nissan discontinued the 3.5 Nismo cat-back. You can still find a few on ebay, or you can go with the 2.5 and get the required part fabricated.

I went with the Borla axle-back, and it sounds amazing. You will not regret it. $631.95 on Amazon with free shipping.

Yeah, try to get it anywhere besides the dealership.. they'll rape you on the actual price of it + plus installing it, which you can do in under 1 hour with little more than a couple sockets and a jack.

With the intake, I'm almost 100% nothing changed engine-wise that would make an intake work for the coupes before '12. In fact, I think nothing has changed engine-wise since the release of the coupe (maybe minor differences, but nothing too crazy). My GF got me a DC Sports intake for my '08 coupe for Christmas, and I'll be getting it in the mail soon hopefully.. I told her to get me that instead of the more expensive Stillen, AEM, K&N etc because at the end of the day, they're all more or less a metal pipe with a filter that improves airflow over stock.

Just my opinion though.

[funkee]

mattyfo0z: I wouldn't bother with an intake. But if I ever did, I would certainly go with a reputable brand. The intake is one of the most sensitive areas of the car. If any part of the intake fails you might suck in some nasty s*** into your engine that could cause very expensive, possibly irreparable damage.

That's why I've been holding off on getting an intake myself. My engine is under warranty. If Nissan's intake fails, I'm in good shape. If my ebay intake fails, and I suck in some sand, gravel, bugs, water, etc - there goes my engine and a p0rn load of money. If the only gain from an intake is sound (and there aren't any worthwhile gains in hp or mpg) then it's not worth the money and the risk.

The only intake I have ever seriously considered was K&N's. They have a guarantee that if the dealership refuses to repair your engine under warranty and blames the intake, they will duke it out for you. That's still a lengthy process, but it's more of a promise than some ebay seller will give you. Check it out here: http://www.knfilters.com/warranty.htm

That's the intake I will likely purchase today: http://www.knfilters.com/search/product ... 69-7062TTK It hasn't been officially cleared for the 2012 on the web site but they say the fitment is the same as the 2011. The HP gain is right at 10 ponies - that's significant (at the wheels)... The Dealership is installing my Borla axle back system this morning and I'm hoping for a credible increase in power. When its all done I will report the results.

I really like the way the K&N isolates the filter from the heat of the engine and still allows the factory cold air duct to plug into the side. The system actually looks factory with a performance twist..IMO

The 9.36hp gain is most likely the maximum obtained on a dyno by K&N throughout many runs. Their site does not say that it is the average increase, nor does it say it was tested on our exact vehicle, or that the vehicle's other components were stock.

It does state: Horsepower gains based on similar vehicle dynamometer test. Results will vary.

If Nissan could squeeze out a few more ponies or mpg, from something relatively cheap like an intake, they would have. Nissan devotes millions to R&D, and although they do divert some of their top-of-the-line stuff to Nismo, I have no doubt that they spent plenty of time and money testing our stock intake.

Having said that, it will increase air intake. Will that translate to a noticeable gain in horsepower? Unlikely. For the intake to have a significant effect, the exhaust - from the headers to cats all the way down to the tips needs to be freed up. That means wider diameter piping and fewer catalytic converters. That alone will give you a noticeable gain, because our stock intake is quite good. It's the exhaust and the emissions standards we have to abide by, that limit the engine's capability.

Imagine taking a huge deep breath and then whistling the air out. When it's time to take another breath, you're still left with a bunch of CO2 in your lungs. Bottom line, it's not going to be very effective until you free up the exhaust system. The K&N will sound louder and it might feel faster, but until I see a stock Altima on a dyno with only a K&N delivering 9-10hp gains, I'm not a believer.

The Borla axle-back will sound very nice. But the most limiting factor are the catalytic converters. Unfortunately, here in Cali, you can't even delete one of the three and pass a "visual" inspection.

True, but I've never had any problems with knockoff intakes on my two last cars so I feel I don't have much to worry about.

I don't know if it's like this everywhere here in CA, but I've taken a handful of cars to get smogged before and not once has the shop lifted up the car to do a visual inspection. They do pop the hood and check out your setup, though.. so an intake or header with no CARB stamp will probably fail you on the visual part. I myself won't be too worried when it comes time to take my car to get smogged with the RL y-pipe + full exhaust. I'll probably take off my intake just because it only takes about 15 minutes and I'd rather be safe than sorry with having to pay again or get my car resmogged.
