the difference?
 

So I've been browsing around for a drop in filter and so far I'm leaning towards the K&N filters, I recently came across this on Z1 HKS Super Hybrid Air Filters (370Z / G37) What are your thoughts on them? the kit comes with 2 filters for $68 compare as to 46 ea for K&N. Anyone has any thoughts on them? I know HKS makes great quality stuff but thoughts would be helpful.

Seriously, spend your money elsewhere. 3-5 hp difference you are not going to feel. Do something like fang vents for about the same...

well I recently had a great in depth talk with someone about after market intake upgrades, and to my surprise he recommended drop-ins instead of upgrading to long tubes, for the sake of confidentiality I will not say who and why. But I trust the guy because he knows what he's talking about and ever since then I've scratched out Injen and Stillen longtubes on my list.

Yes, because solid gains are bad. :rolleyes:

lol

wanna buy my takedas

:roflpuke2:

drop-ins gain about 1/5-1/3 of the power that long-tubes or a setup similar to modshacks do...

well this is what he told me, if you just do an intake upgrade and everything else stock sure the Stillen and Injen will show 10-17 HP gains but once you decided to upgrade other things such as exhaust, headers and high flow, the intakes will not come in the factor of adding HP if not any. So he recommended to just get a K&N drop in filter. He is not K&N sales person nor is he a stillen / injen person as well. It's just his two cents and he's got data to back it up. But I don't want to give out names because I don't want people to flame.

lol

its not spawn is it



:bowrofl: j/k

Well, FWIW, I did the CBE and HFC upgrade first. Then I did the G3 intakes afterwards, and if I remember correctly, I got a solid +14whp gain from the intakes, having done a baseline dyno after installing the CBE and HFC. Give me a minute and I'll dig up the thread for you.

Here you go:

Gain was 14.7 on Dyno Dynamics.

:iagree:

this thread is like playing with matches near a leaking propane tank...

:owned:

Your source's logic doesn't make any sense. Intakes are designed to pull in colder, denser air to increase the efficiency of the burn in the combustion chamber, along with higher flow, and in our case messing a little bit with the mass air flow sensor positioning and tubing to lean out our air fuel ratio a tad.

Adding in other bolt ons generally increase flow on the ass end of the engine, which only makes the longtubes a BETTER choice since you will relieve all of the bottlenecks in the system. If you just did drop-ins and a full exhaust, your engine choke point will likely be at the intake since it won't flow as much air as it could, restricting horsepower.

lol kdo it's not spawn, it's someone that knows cars really well and the reason why I'm keeping confidentiality is for the sake of him and I don't think he wants reps from Stillen or Injen to know that he's saying things like this, and trust me he is not bashing on them it's just him being honest to me on what he thinks it's worth the money, remember guys, Long tubes have more bends and longer distance to travel then the stock airbox, the stock airbox is restrictive at top end. I can definitely go and drop $550 on a set of long tubes but realistically after hearing what he had to say and his data to back everything up I don't think I'd want to do long tubes.

semtex is right jake...

the z performs more efficiently with straight pipe long intakes as opposed to the rigid corrogated stock setup or the takeda setup im running mine just sux in all the hot engine bay air and thats nogood for hp gains...

nissan did an excellent job of sealing up the engine bay so not alot of fresh can get in unless some sort of mods are done to help the fresh air get in

I think we're trying to be constructive and help Jake out. ;)

My thing is, I would like to see this "data" you are speaking of.
Everything that has been posted on these boards have shown Stillen or Injen intakes are going to show positive gains even with other bolt on modifications.

and im having a 04.5 sense of humor moment :rolleyes:

Kdo did you get your takeda's dyno'd?

^ I will talk to him privately to see if it's okay for him to mention his name or maybe get his data to back it up. As far as I know he's a very respectful person when it comes to our car. But lemme find out exactly what I can do to show this data or not, and yes thanks everyone for the constructive discussion, it definitely helps when you get inputs.

I did the dyno (-2HP).

no because dreamer did and there was no gains according to his dyno so i felt it would be a wasted of money to do...:ugh2:

I seem to recall KillerBee not seeing much gain out of the G3s.

Did you reset the ECU?

Was his the Technosquare ordeal, where they did a base and then full Stillen bolt ons and got 15 rear wheel HP and then Tehcnosquare tuned the car and was showing gains of another 30 rear wheel HP or something?

indeed... please stay away from butt units too...

Yep, Takeda went back and did a dyno themselves with Lou @ Amplified and got a gain of 7HP in the end. The difference was I do close hood dyno runs and they were doing open hood dyno runs. They claim that an open hood on SRI setups are "more realistic" to the air flow, I was not convinced on that though.

Yeah, I think so. And then that other 370 site did an article write-up based on his ordeal making it sound like the G3 intakes don't yield much.

That was an interesting time, nothing really came out of it other than Killer has plenty of power in his Z, which in the end is all that really matters. And he loves his car. :D

Considered a competing blog/forum, I guess. I deleted my post out of respect for AK's wishes.

why are the g3s being reffered to as long tubes? pretty lame.

Because they're long tube intakes. Also because Stillen makes short tube intakes, which they call the G2.

Chuck, here's a link to Stillen's product page for the G3. As you can see, they themselves call them long tubes.

STILLEN : STILLEN Generation 3 Ultra Long Tube Dual Intake Kit

The tubes are pretty long. LOL.

With the current information it is difficult to come to a definitive conclusion. When Technosquare did the original test of the G3 on an automatic, it actually lost hp in the low and midrange and gained a little on the high end. This test was done with the front bumper on and when they removed it they showed a gain over most of the range. Later they did a test on a manual and they showed some gains with the bumper on and more with the bumper off. Others on this board show good gains with the bumper on.
I think one thing is definite - if you perform the Modshack vent modification you will measure gains regardless which intake you are using. This mod really forces cool air into the intake. One other thought - I really think that there is no way valid way to test most modifications on these cars even on a dyno. When you deal with heat soak, trying to guess how long the ecu takes to fully register the changes, and not being able to create flowing air into the engine, the results will always be suspect.

The G3's are Ultra Long Tubes

Hyper Long Tubes!

Yeah you're right. The G2s are long tube, and the G3s are ultra long tube. I guess that makes them ultra lame. :rolleyes:

So what's a short tube, does the air filter stick directly on the throttle body??

STILLEN : STILLEN Generation 1 Short Tube Dual Intake Kit

It's the G1. Not made for the 370, but for the 350 as well as G35 and '08 G37.
