The Injen is good also if you would like to skip the cutting.
I believe it showed maybe 2HP less at the top end but the whole curve was similar. Only issue with Injen is you have to be careful with water as the filters are much lower, now a small puddle is fine but 1 foot standing water is a no go of course.

Yea that injen isnt an option for me for that reason. Also dont you have to re-locate the washer fluid reservoir or something? My only issue with the Stillen is finding someone I can trust with dremel work. I've been down the road of heavy modding before and as soon as things start to get cut and re-attached it bothers me. The last thing I'd want is someone rushing through it and making the whole not large enough and having the intake pipes rattling. I wish I had the skills to do it myself. I'm NOT mechanically inclined at all. It's sometimes a challenge to find speed shops who will treat the customer cars as if they were their own, and not charging $90+ an hour for their work.

You replace it with a smaller washer fluid reservoir, so in the same location but less volume.

Stillens are the best performers and removing the bumper for a once in a long while maint isn't a big deal. I'm on stillens Now coming from Injens and couldn't be happier. All short intakes have an advavantage of easy maint but little hp gain, You're better off with the stock boxes and K&N drop ins.

Op: I'd suggest looking at this DiY to have a good idea on how to remove it so you're not paying someone to do it also suggest going to a local meet and talk to members who have done it, and show you exatly how to do it if you're still unsure.

now that I think about it, 17.5 whp really is a tremendous gain for just an intake on a 6 cyl car....

bigZ · 03-02-2011, 01:10 PM

That is really nice! Thank you all for the help and advice.

What about Exhaust?

BLM · 03-02-2011, 01:13 PM

Exhaust is more about preference of design and sound. Stillen claims 18 whp. Fast Intnetions is very popular. My fav is the Berk.

bigZ · 03-02-2011, 07:05 PM

Sillen all the way!!!! Do you know a good place to purchase both the Stillen G3 intake and catback?

If you go with a shielded short ram and perform the modshack vent mod your air intake temps will be as low as the Stillen or Injen. I have the R2C and the vent modification and my intake temps are no more than 8 degrees above ambient temps.

Longer tubes should move peak torque down if they do anything.

The major advantage must be that they just sit in front of instead of behind the radiator.

I've yet to see clear dyno evidence where any of these aftermarket intakes outperform high flow panel filters + smoother tubes, at least on the 370Z. The OEM airbox already ducts cool air in from the bumper and has excellent heat shielding.

It looks restrictive, but it's really not. Nissan did a good job on this airbox.

Also try the search/advanced search, it's not hard it may take some of your time.

#1 was R2c
#2 was Stillen Gen 3

... on my 2010 G37xS sedan with ERZ HFC and FI CBE.

Stillen has the best gains, without a doubt, but at the cost of a more difficult installation/fitment issues with the tubes/AC lines/frame. You shouldn't have to clean the filters until 50,000 miles, depending where you live. That's Stillen/K&Ns recommended interval.

Since you're looking for an easier install without any permanent modifactions to your car, go with the R2c system. They are the best SRI IMO. Best filters in the industry, sweet black nickel finish, and they have a very nice refined (yet loud) tone to them.

Hps + k&n ftw

Jordo! · 03-08-2011, 03:45 AM

BTW, that other dyno above showed a gain of about 3.5% for the exhaust and 2.5% for the intake -- this is also in line with what I would expect from a catback (with OEM cats) and an intake (panel fitler or otherwise).

Again, raw values are far more misleading that proportionate gains -- there you should see a lot less variance from vehicle to vehicle, and dyno to dyno for a given bolt-on.

Keep in mind I have an awd G37 7AT.
