Just installed Stillen G3 Intakes

bebenegro

First of all, thanks to Jomar at FBNissan for his attention and support. I bought the intakes about a week ago, they arrived yesterday, and my cousin and I did the install today. The install was fairly easy - I followed the instructions on AK's DIY and had no problems.

Im still waiting to test them out, as it was raining cats and dogs in the afternoon, but tomorrow I have a 70 mile drive to do, so, Ill post impressions soon. So far I can say that the sound up top is much improved. At low idle, and cruising though, you dont hear that much of a difference. Guess an exhaust is next on my list of mods.

Im attaching some pics of the install.

I want to get one, but I wonder how much of an improvement over the z1 silicone hose and k&n drop-in..

It will be a good improvement. Defiantly worth it.

If you just do a search the gains on both set ups are extremly well documented

I wont be doing a dyno, but Ill let you know my driving impressions after I drive back home today. As for gains compared to a drop in, it should be significant. The configuration of the intakes compared to the stock air boxes is completely different.

I wouldnt say that the stock air boxes were bad (compared to other cars Ive owned in the past), but the Stillens seem to be very well designed - particularly in providing laminar air flow to the MAF so it can make a proper reading.

One quick question about the installation of the Stillen intakes... Is there any modification needed to other parts of the car? I've read conflicting stories about some grinding/metal removal needed or not.

bebenegro

The only modification needed is a small bit of grinding of the front of the air ducts that fed the stock intakes. You actually remove the rest of the plastic duct, as its no longer used. This part scared me a bit initially, but it was actually really, really easy to do. Just make sure you have a decent cutting / grinding tool. The cutting didnt take my cousing and I more than 5 minutes total.

Now, as for impressions...

Today I made the 70 mile trip back home. I took it slow for the first half of the trip (slow as in normal, non spirited driving). I wanted the ECU to fully adjust to the new intakes. First thing I noticed, upon normal driving, was an increase in MPG compared to the stock intakes. I used to get an average of 20.9-21.1, now Im getting 23.9-24.1. I somewhat expected this, as I noticed a similar jump in mileage when I installed an intake in my previous car, a Mazdaspeed3. In that case the jump was larger (from 21 up to 27), but that was a turbo car.

On the latter half of the trip, I sped things up a bit, doing some 2nd and 3rd gear runs in some straights of the highway. I have to say. the car pulls harder... But really only after 5K RPM. I dont notice any difference in performance in the lower RPMs. I guess Ill be touching redline a bit more often now!

In terms of sound, again... Down low, not much of a difference... But up top? Man, this is how I expected this sports car to sound. The car comes alive at high RPMs.

So, thats it. If anyone has any questions, feel free to ask.

Thanks good to know! +rep

4-5 for tube, 4-5 more for drop-ins so about 8-10 hp compared to 14-18 hp from gen 3?

Awesome! Thanks for that info. I think I'll step up and do the mod,

And don't forget to wrap the ac lines so the intake doesn't rub thru it. But I agree def worth doing I've noticed power right around 3500k-4000k u can hear it start sucking a lot of air in and ur gone. Check stillens website they run deals if u buy their exhaust u get the intake like half off.

Hate to bump an old thread, but had a quick question.

Can I install the Stillen G3 intakes on my own? Also, I was warned that I may need to remove the front bumper to change the filters?

Just looking for confirmation; thanks!

3zworld

You can do the install on your own as other than removing the front bumper cover and shaving the core support a tad it's really a direct bolt-on. Unfortunately in order to change the filters every time you would have to take the cover off, something that has made me consider selling mine and going back to stock.
