Is the G2 CAI respectable?

That is what I have on my car now, and I am just wondering how it compares.

from what I understand, all brands of cai are about the same in performance.

G2 utilizes the stock airbox...which is NOT comparable to other cai's. G2 sees the least amount of gain from all other cai's.

I just got one.I previously intalled an slp cold air in buddies 97 bird and didn't like how it fit in the car at all or how the filters where no so low and underneath the car.I was almost going to buy the k and n one but at last minute saw the lg one and bought it.It doesn't use the stock airbox it has its own and modified front piece.It has got to be better than stock,looks very fast to install and doens't hang under the car like most of them.
I would think if a k and n or slp type maybe adds ten hp then maybe the lg will only add 5 hp ,but willing to take that compromise.Cold air is not a huge power increase anyway really compared to differences you gain from cam/heads,different gears or stall converter.And this isn't my hardcore car so that was another reason went with simpler and maybe safer in heavy rain lg one.I would like to see actual dynos comparing the results with this one and some of the other ones.But oh well whatever..Times in my sig are for 96 totally stock.Car is in winter storage yet so no new times until spring.

Getting colder air into the car isn't important? The reason they hang lower is to get the cold air from down there. The G2 is better then stock but not much better and not really worth the money imo. I would get yourself a used CAI. You can get them pretty cheap.

I had the G2 before I got my cai. I didn't like it at all and I don't think it's any better than stock. They should call it G2 warmair.

Edit: To expand, the G2 is made of urethane and plastic conducts heat at 1/30th that of metal. So it will retain more heat. Second the air channel running between the filter box and the MAF seems smaller and more restrictive that the stock one. This is why I didn't like the G2. I would suggest buy a used slp or just put a k&n in you stock intake.

Lets see some proof of your statement. Everyone says the G2 is just as good as stock, but when you ask for proof, they don't provide any. Hmm, interesting if you ask me.

G2 being just as good as stock...? You're saying it like it's a good thing...? G2 pulls air the same way that the stock airbox does, whereas the Moroso, SLP, and K&N pull cooler air from directly behind the front dam. That by itself is proof enough...

I'm sure there is someone on here who has actual proof...

I've tested a Moroso and a G2 with my Scanmaster's Grams Per Second function and they both flowed the same. I will say the plastic in front of the air filter on the G2 was completely cut out. Saying the whole area of the filter was open to the air.
As far as temperature of the air being inducted, with the Moroso it was what ever the outside temp was. With the G2 it was a few degrees higher. Also have to say I have a scoop in front of the air dam, forcing air up into that area. With out the scoop, I would think the air being inducted by the G2 and the Moroso would have been warmer.
Another thing about the G2, the part that connects towards the MAF is about 1/4" larger than the Moroso.

HUH? I guess I don't understand what you're trying to say. Metal retains heat much more than plastics do. The SLP CAI is metal. So, how does the SLP CAI make more power once the engine bay is warmed up?

Well I guess dyno tests would be interesting.My main point is that doubt even the slp or k and n gives more than 10rwhp so if the g2 still gives 5 to 7 not much difference and I personally don't like the air filter under the car down there.And anyway we are talking a minor mod at best here guys.maybe a tenth tops in the quartermile.not very significant compared to other mods like gears,stall converters,headers,cams,etc.Still I know they all add up.

Anyone have the AS&M CAI?

I think it's one of the better ones?

Just wondering.... When I got my car it had the SLP CAI on it...Didn't like it. Don't see how 2 filters and 2 tubes so close together out perform a single Filter twice it's size.

Switched to AS&M nice crome pipe single air inlet...and it felt much better.

No, I was saying that plastic does not transfer heat as well as metal.

It isn't as an important mod as a cam and headers but it is a very important mod imo. When your higher in the hp you car is gonna be wanting cooler air and is gonna want more of it. If you car is giving it hotter air and if its being restricted then you power will suffer. It alone isn't such a major mod but it helps out all the other mods because it is what gets the air into your car.
