If you can find the G3's used, go for it, otherwise, I'd recommend going with the alternative I noted.

Do you have dyno graphs of this to prove it?

i have been searching .. but i, like everyone else (at least thats what i think) find different opinions and different experiences with them.. and every opinion is greatly appreciated. I will look deeper about the G3s though :)

I didn't have to fix my injens. They just work and are awesome. Just gonna hear this community drone on about the stillens, which require cutting to install and bumper removal for filter replacement.

Both do the same job. Whatever.

If you search, I've discussed this at length... this conclusion is based on observing multiple dynojet results, across several vehicles.

If you disagree or wish to dispute my conclusion that's perfectly fine... spend your cash as you see fit :tiphat:

damn.. the more i learn the less i know .. all i know about their performance of these intakes is what i've read so far, but the pictures i have seen the G3s look neater once intalled and the sound is nice and clean. Ill like to learn how to do this myself.. anyone from Hawaii ?

G3
 
I was considering the G3 but found, after looking at the dyno chart on the Stillen site, that the majority of the gain is between 6500-7200 rpm. The mid range is significantly less gain. I don't drive much at the redline so I didn't think that a 2-4% hp gain in the midrange rpm's was worth the install, maint. and $600. You can check out the chart at the Stillen site.

I have the Stillen CBE and love it. Nice resonate tone, kind of like a stock G37 sound on steroids with no drone at all. Butt dyno says the power is improved.

Stillen is a class company and makes great products so I would go with the G3 if you think the power is desirable for your driving style.

Trust me, if the research of dyno charts with the same other parts would typically read the same results I would GLADLY get the drop-ins with post maf tubes... I would probably get the fang kit to add a little more cool air though. Anyway... please do point me to the thread(s) that show the same or better gain. Obviously I don't want to spend over 500.00 if I don't have to.

the injens don't give the same results.

the postMAFs and filter are lucky to give half the gains of the stillens.

truthfully i havnt seen any dyno's to show this and ive been here quite a while and read all the threads.

being someone who has had both setups, i can tell you that the most mafs + drops dont come close to the power than the stillen would make up top. under the top end they are comparable.

I think that people are just weighing if the power up top is worth it considering that many of us don't run our cars all the way to 7 grand or more. However they the power up top cannot be denied either.

Curious to know why the JWT Pop chargers have not had a mention, surely they must better than drop ins ??:ugh2:

We've seen some reports of water problems with Injens in rainy / humid weather too. The reports are that the filter material is fond of restricting in high humidity (post-rain) conditions in general (leading to engine failing to start), and that because of the tube layout rain runoff tends to run down the tubes onto the filters as well.

Those are primary concerns about the Injen solution, not the performance.
