Easy to say when you are your doing a butt dyno. Show me a dyno and prove me wrong otherwise ill take a shops word than your opinion.

If you havent noticed almost everyone thought the Airaid did well and then they were surprised after they did this test. Even retesting it on their other 2 test cars with the SAME results. Other members who own the intake also did the same thing and got consitant results that matched the ones in this thread. You are probably the first person I have seen that doesnt think this dyno is junk. Lots of members have already tried to sell it or get rid of it with no luck even for cheap.

Since you own the intake itself its hard to face the facts when theirs multiple dynos showing us otherwise. What you might be thinking is a placebo. Obviously throttle response is a little bit peppier but intakes dont show any true power till the cars in the higher rpm's which I doubt you could tell the difference between a couple less or more whp.

Go to a shop and do a dyno then post your findings until then Ill trust the multiple dynos on this site thats already been done and proven that the Airaid is crap. Imagine if the hood was closed also since these are with the hood open. Cant imagine how much worse it would do. Even Airaid posted saying that their customers have seen a difference in their car but when they were asked how many of those customers actually had a dyno done with the intake since then they have mysteriously disappeared. Any real company that stands behind their product would of proven that this information provided was wrong by retesting their product which still hasnt happened yet since the start of this thread.

Shit we might as well not dyno any intake then if thats the case. Why do dynos at all fuck. Forget it then if doing dynos is pointless since their not real driving conditions.. Dynos were done with the hood closed by another member and it still showed gain. So if the Airaid lost power then imagine how much more it will lose if the hood is closed. Same with any other intake that is showing little gain. They probably will lose some also. So its safe to say the Injen will gain power just not as much as the dynos say since it is open hood.

Another member did do a dyno with the hood closed and it showed gains so what more do you want? Like it or not its data and I would feel a lot more comfortable purchasing an intake that has gains on a dyno then losing power like the Airaid. If dynos are so useless for such data why would vendors even bother showing us this information and why would so many people base their decisions on this information when you say otherwise. Face the facts the Injen is the best intake right now on the market lean or not its still performing the best out of all the intakes out right now until a true CAI like Perrins is released. Only then we will see how theirs will do. They even said they were surprised at how bad a lot of intakes did after testing out others. No surprise that most of them did like crap and probably Injens and theirs had the best performance on the dynos.

I didn't read the whole thread, just skimmed after page 1, but is anyone looking at A/F compared to HP/TQ? It's VERY clear that the ones making the most power are the ones leaning out up top, and the ones making the least power are the ones running pig rich up top. The AirRaid is off the scale lower than 10:1 for a good portion of the run!

These results are good to see how a bone stock car will react, but if you want the most out of an intake I would get the one that flows the most (regardless of power on a stock tune) and get tuned to match the flow of the intake. I bet with a tune you would see the AFe or AirRaid make the most power overall. I doubt you would see much gain at all with a tune on the Injen since that secondary tube is already leaning out the top end for you.

It's simple. One is a CAI, one is an SRI and one is in between. When you dyno an Injen with the hood open, you're turning it into a CAI...which it isn't. Our engine bays are hot as hell. The AIRAID heat soaks like a mother.... and that's plastic. The metal Injen would only heat soak MORE... and stay hot because there is NO cold air to cool it off. The results are skewed at best.

So no, it is NOT the best intake. Aside from the lean (which IS dangerous to a motor), it's the hottest running intake....which only increases the chance of knock. Unless, of course, you don't believe in simple automotive science. Add a tune to even the AFR and I bet the Injen would get owned, hard. It would no longer have the lean condition "masking" the problem of hot air.

I'll put it in laymens terms for you. Hot = bad. Injen = hot.

Close the hood and redo this same test in a regular environment with outside temperatures. Willing to bet that Injen doesn't enjoy that hot air from the engine bay. Every CAI I've own in the past always tries to get away from the engine whether it goes closer to the ground or more towards the front of the car... I've never seen a "good" intake sit in the engine like that and produce power. I could be wrong, but that's what it looks like from my view. I'd want my air pulling from that front bumper all day unless someone finds a better way. Not to mention I've never owned an intake that was metal either.

It will still make *some* power because it's leaning the car out (dangerously, IMO). But you're correct... It will get hot as hell, quick.

Yeah, that leaning out is a huge no for me. I love my gas mileage the way it is, and don't want any future problems from long term use.

you all are run this un-tuned?

My injen in the summer in Phoenix was never really that hot you could always touch it even after a long drive it doesn't seem to hold alot of heat

Have you ever done temperature logging? Or do you have access to an temperature gun?

Yeah I have one its a cheap one but does the job it was only at 120 degrees after running when the outside temp was 115 it seems to be designed to displace the heat very well. I have never had an issue with it and it was a noticable difference in power when I put it on and with my Greddy SP Elite exhaust it sounds really good. I did have a tune with it for a bit but with the chirps I took off the tune and I am waiting until it gets fixed before I put the tune back on.

Yea, that makes sense. There will be a much lower delta (temp difference between ambient and air temp) when you get THAT high. 120 degree intake temps are very high in and of themselves. I didn't even see that high of a temp with the AIRAID idling for 5 minutes after fully warm.

You should do some temp logging now that I'm assuming AZ has more "regular" temperature ranges... being December and all.

Going up to Vegas this weekend I will check it every time I stop and see how it does

I took the snorkel out of my bumper and the gap is pretty much the same and with out the snorkel according to the results my car pulled in about 7 more g/s and kept the intake cooler during wot with the stock intake and hks intake filter. Only thing is that when the car is idling for a good amount of time the intake ran really hot. Injen has been in the game for quite some time and maybe theres more to their design than we know..who knows!

And if im not mistaken doesnt hot air always rise and on the top of the box there are vents, maybe they serve more purpose than we think!

Agreed, injen has a great rep and we can't physically see alot of the technology that goes into their intakes.

[nbafandan]

Is there a thread like this but for exhausts instead? *not just clips of exhaust systems*
