For people that don't want to remove the front bumper lets say yearly to clean the filters, would you recomend the G2? and how much of a performance differance would you expect to see from G2 to G3?

efuseakay 02-13-2011 06:57 PM

The filters can go 50,000 miles before cleaning. The G2 won't give you anywhere near the gains as the G3. If you're going to go short ram, I'd look at the R2c system.

TripleBlkZ 02-13-2011 07:20 PM

50,000 miles really? lol I won't need to look at it for 10 years for as much miles I put on it...Josh can you confirm this? my only concern is having to remove the bumper yearly to clean the filters. I live in the city so beside regular construction I won't see much dust...

SPOHN 02-13-2011 07:50 PM

Removing the bumper is not hard at all. Especially once a year. It took me 5 minutes tops.

Yes, K&N recommends 50,000 miles on conical filters, and 100,000 miles on panel filters for cleaning.

I'll be honest, most enthusiasts shoot for ~30,000 miles, but you can always clock the filters every 6 months, airflow always seems to follow a pattern, and certain areas will see more flow. So by moving them a bit, you'll get the same filtration, without having to clean/recharge them.

But the increased performance from the Gen 3's will make up for any extra effort, which once you've removed the bumper will prove to be minimal, as others have stated. Highly recommend going for the G3's.. especially with this month's special..

I didnt want to open a new thread, hope thats ok !

last week I installed my GEN3 and today I took the car to the dyno again. As you might have seen in my video thread I was able to realise a gain of about 6WHP compared to base line dyno with my cat-back exhaust system.

So I was very excited about how much the combination of exhaust and stillen intake will give me.

Unfortunately it looks like the intake actually steals me a lot of HP :(

we did like 4 runs in 5th gear (7AT) up to the vmax limiter and there was a significant loss compared to stock intake and CBE. However the curve still went up when the speed limiter hit so is it possible that the stillen AI moves the powerband way up the revs ?

Surprisingly when we tried to measure in 4th gear we made 2 runs with lots of wheel spin on the dyno even with a 260 pounds guy on the passenger seat. Last week with just the CBE dyno in 4th gear was no problem at all.

So it "looks" like we gained lots of torque and power from the G3 ... BUT ... after putting like 10 car batteries in the trunk plus the 2nd person in the car the dyno was actually able to measure without spin and again, we saw a lot less HP than we had before :(

is it possible that I need to reset my learned ecu values completely and drive the car for a couple of miles before the ECU can take advantage of the G3 ? I just cannot believe that this well recognized and prooven system will really cost me HP instead of gain ...

just to make clear, I drove the car for about 60 miles both in the city and on the autobahn and we did like 6 dyno runs in total - not enough time for ecu to recalibrate ?

please let me know cause it took quite some time for the install and of course cost quite some money and currently I'm really not happy at all !

My girlfriend just ordered the intake for me last night for my bday next week. Excited to get this one on now. I had one on my previous 370Z but I wasn't able to salvage it, so a new one on the way for the 40th:tup:

LinPark 03-26-2011 07:50 PM

There is a small self-contained box that hangs onto the bottom of the stock intake on the driver side - what is that thing? I assume it is not needed for the Stillen G3's since there is no way to connect it?

Jquad 04-09-2011 02:16 PM

what is the torque setting on the strut tower brace?

christian370z 04-09-2011 04:23 PM

52 ftlbs is the torque figure in the service manual for the brace bolts.

Thank you for the write-up! I wasn't sure if a CAI would be a good idea since I live in Oregon and it rains a lot. My big concern was buying something that sat too low and would end up creating a mess. You beat me with living in a flood zone though lol. :)

Is there anyway to do this without cutting any parts?

Nope. The intake tubes simply don't fit without grinding the ducts down. I did my install today. As long as you have a dremel it's really easy and just requires some steady hands to get a nice cut and sand on them.

EYE ESS 07-03-2011 11:43 AM

Stillen Gen 3 Intakes and Exhaust came to my friends job on Thursday night. Friday afternoon he put the exhaust on for me...Saturday morning I put the intakes on. So I didn't let them collect dust at all. I reset the ECU and had to fix the auto up on windows. I didn't do the pedal dance ecu reset like I should have since I unplugged battery...took no chances!

Definitely invest in a Dremmel, or just buy one use it for 5 minutes and return it. either way works.

Car definitely pulls harder, but engine is still breaking in so I gotta wait a little longer to see cars full power.(I installed both of these parts at just under 1000 miles lol!) The car sounds amazing, you don't really hear the intakes as much as the exhaust. I've already gotten a load of compliments, the thick exhaust tips are very sexy. I just have to adjust the exhaust a bit next time it is on the lift. One side sticks out more than the other. Should be a simple fix.

HFC's coming before end of year...or in the spring, haven't decided!


Also on a side note, I did not remove the brace, saw no need to since there was plenty of room. Also I used the suggested fix to clear the AC lines by slicing the second tube in half and wrapping the lines. I only had a little duct tape so when I go clean filters I'll put a stronger adhesive on.

Thank you.

weezal657 07-12-2011 07:58 PM

One quick question about dremmeling, after the sides are cut (assuming you cut only the needed amount for the hose) would you be able to re-install the OEM intake without any issues? Only asking because if hell froze over and the wife could pry the key outta my hand and we had to sell the Z it sometimes seems easier to sell it back as stock. Thanks.

This (x2.)

I'm reverting my car back to stock, but my question would be if the functionality of the OEM intakes still be the same with the cuts made on those passages?

EYE ESS 07-13-2011 02:05 PM

I'm unsure, if you really had to leave intakes in I don't think it would be the end of the world. Don't mod if you are in a lease. It really depends on how big you make the holes I suppose, you could always try stuffing the stock pipes back in.

AppleZ 07-17-2011 09:11 PM

With the help of my brother, I installed my Stillen G3 yesterday.

First off, a big thanks to AK for having this play by play thread, and thank you for everyone's contributions throughout. I wanted to note a few things I had troubles with and a few areas I felt were easy for me.

Like everyone said, the bumper was really easy to take off. Nobody should turn down the opportunity to purchase this badass Stillen product because of the bumper removal. Everything else was very easy to remove. Based on the suggestions of some, I had removed the brace to make it easier to work with. A little additional work, but seriously only about 20 minutes added to the install time.

A few pointers I have to give during my time installing this:

1. I avoided a cutter of some sort when boring out the hole. Instead of using a Dremel, I used a power drill, with a bit attachment. The attachment is this one from Dremel: 124 High Speed Cutter / Model: 124. Very easy to use and allows you to take your time without screwing up anything. I think it was about $10. Each side took about 10 minutes each to drill out. Very precise, and the holes turned out very well, very snug. Pic below of the passenger side (I'm unsure if this was taken at the final stage of boring out, because I had to go back and shave a little more off to get the pipe through):

http://i1213.photobucket.com/albums/...g?t=1310952482

Here's a picture of the driver's side w/ tube throught the duct. Turned out to be a really smooth and tight fit (that's what she said). :tiphat:

http://i1213.photobucket.com/albums/...g?t=1310954544

2. The pipes were a b|tch to configure. Twisting them and dealing with the fittings were a bit of a puzzle. This was the most difficult part in my opinion. What made it so hard were the filter locations. The filters were butting up against a screw in the front frame, which we tried our best to avoid on each side, but it didn't jive. In hindsight, if I had the right tool, I would have cut the excess screw off. We had to deal with the snug placement. I wish I had taken a picture of this.

3. When disconnecting the battery, remember that your auto-up window function gets turned off. Refer to your manual as it has a step-by-step to restore the default. I was flippin out for a moment on that one.

4. We didn't use tape or an adhesive to keep the rubber tube attached to the A/C lines. Instead, we cut one of the rubber tubes that were included in the kit, and placed it over both of the lines. To keep it intact, we used plastic ties. Those things aren't going anywhere. One thing to note: attached the rubber tube to the A/C line before doing any drilling of the ducts. This will ensure you do not slip and F up your lines.

5. Take a look at AK's wiring around the driver side tube. Look closely at the placement of the wiring around the driver side cone, to be more specific. We had a bit of trouble getting the placement right. After examining the picture, we had to unclip the wiring from the brace, and place it like so:

After the install - ain't she purty?:

Video of how it sounds: VIDEO


In summary, this add on was pretty easy to install. Total time was about 3 hours, with most of the time spent aligning the pipes. Bumper was very easy. A lot screws, but no time at all to take off. Your new intake sound kicks in around 5500 RPM's. I have noticed a difference in both sound and performance. On my way back to Austin From Houston (162 miles), it took about 1/4 of a tank from a full tank. My guestimates are that a full tank with intake will achieve 400+ miles. Not too shabby for a sports car.

Next up, cat back exhaust. I think I'll get that done the same time I have an Oil Cooler installed in a few months. :hello:

Ha your ride's description should read, "Drive's his brother's 2011 370Z." ha. Good install together.

i have a question
what is the function for the air ducts?
is it possible to install the intake without both of the air ducts?

I would assume so, but the main function they I see is that they keep the tubes in place. Without them, the tubes are basically floating...

Great job on the DIY!!! You make it look so easy even Ray Charles could install a Stillen air intake....I just bought my 370Z a month ago and the next move is the air intake.... Thanks BRay


PS: I have the paddle shifter AT and I got 3rd rubber the other day, imagine now with an Stillen...ya baby

Next is the oil cooler. I'm quickly realizing that it needs to be installed. Dunno if I can DIY though.

Too bad you don't live closer, it wouldn't be a problem to have it done in the garage.

We had the same problem when I installed the intake on my bro's car. Here is how you fix it (from the maunal, page 2-41):

If the windows do not close automatically

If the power window automatic function (closing only) does not operate properly, perform the following procedure to initialize the power window system.

1. Push the ignition switch to the ON position.

2. Close the door.

3. Open the window completely by operating the power window switch.

4. Pull the power window switch and hold it to close the window, and then hold the switch more than 3 seconds after the window is closed completely.

5. Release the power window switch. Operate the window by the automatic function to confirm the initialization is complete.

6. Perform steps 2 through 5 above for other windows.

If the power window automatic function does not operate properly after performing the procedure above, have your vehicle checked by a NISSAN dealer.

You can find the fix in your owners manual if it ever happens again.
