Greetings everyone!

I have a '12 GS w/ headers, xpipe and npp. Is it worth it to swap my intake? If so, any recommendation?

I've heard the best intake (air cleaner) is the one that came from factory.

I have a '12 GS and was looking into it, then people said stock is best.

I don't think there is any gain by changing your intake, the new design (2011-2013) is way better than previous years and flows just fine.

The stock one is good for 436,505 and 638 depending on your ride.... and it actually "filters" the air too...you ain't getting any better then that!

Since you have headers and npp,I would look at the K&N Aircharger intake system. That is what I've had on my 08 for years.

gsvette2012

yes, that is what i have been hearing. the stock intake is best bc it is a 12 gs.

i guess i will stay put and save a few $$$. thanks!

The 12 & 13 cars came with the LS9 (ZR1) air filter from the factory. You don't need an aftermarket air intake until you're pushing significantly higher HP than where you are now.

Honestly, if there are any real performance changes they are minimal if at all, what I have gotten is alittle quicker revving and alittle intake noise, that's really about it.........

Not listening to others I went and had the vararam put in mine. As they say, to each his own. I have the stock CAI from my base vette and my GS sitting in the basement. Anyone know what they're worth by the way?

I cut the 2 pieces out at bottom of the baffle, so with a cam and LT's and Borla Stingers it made a hell of a different.

I couldn't give away the stock setup from my base vette years ago..that was LS2 though. The LS3 I've seen anywhere from free-50-125 in a few places. If the filter is in good shape that will bring 50 bucks on it's own since they're over 100 new at the dealer.

Purchased my 2010 GS with stock exhaust, and Corvette intake. Then added Billy Boat bi-mode exhaust with dead pedal switch. Wanted more, so installed a Halltech Killer Bee intake. Notable hp improvement. Then the check engine light came on... running to lean! Had a custom street tune and wazza... she's a beast. Generates about 480 at the crank!
I think an intake, the right one, can make a difference.

EvanZR1

Exactly how did you measure power at the crank? Unless you pulled the engine, it's kind of hard to do. If you've got a dyno number, use that as adding up vendor HP ratings doesn't work, and calculating crank/flywheel from RWHP dyno numbers can be way off based on what correction factor you use. If you have a dyno number, post it.

It's really humorous to me when people throw on just an air intake and say it made a noticeable improvement. Even if it did add 10HP, that's barely 2% on an LS3, and not something you can really feel seat of the pants. Heck, the difference from a nice cool low humidity day to a hot humid day could see a much bigger difference. There's plenty of people that love to talk air intakes on LS3s, but if you research, you'll find very few that actually show any benefit on a dyno. And before anyone starts going on about them only making a difference at speed on the road, the Vararam is the only one that can really make any claim to that, and even there I think the science is questionable (I think I remember someone doing a test on a Ram Air f-body many years ago, and the speed required to show adjustment for extra air flow was over 100). I think many people that put on an air intake and "feel" a difference do so because they think they should feel a difference. We've all learned over the years that stock air intakes are restrictive and this was backed up by performance gains on earlier models (C5 LS1 & LS6, C6 LS2), but the factory LS3/LS7 air intake is a great design, especially on 12/13 models with the LS9 filter.

I definitely notice a difference driving my car now during the cooler months than driving it last summer lol.

Who needs an intake? Just drive when its not hot out!

Bam free hp!! Lol

billyboy47

both in excellent condition. I'll just give them to whoever buy's the car.

I have a nice Corsa intake set up for cheap if anyone wants one....they look good but I went back to stock.....if the stock set up can take care of 600 + hp its good enough for my LS3....plus it filters the air.......the more air the car gets thru other induction systems is providing less filtration....

Here is what I would do. I put this on mine, ( https://www.corvetteforum.com/forums...ke-shroud.html ) Even after 6 close dyno pulls (in 100 degree Florida heat), it was still getting "cold air". I don't think any other CAI would do any better

Or is the OP talking about CAI?

gsvette2012

I wasnt talking about the intake manifold, HOWEVER, u just peaked my interest.

Worth the $? any significant improvement?
Should i start a new thread? lol
