DIY: Finally Installed The STILLEN G3 Intake today! Lots of Pics inside (AK370Z)

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...

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 !
