That's mainly what I was getting at but at the same time you are always going to be tempted to play with that brand new toy lol

My background is I.T Engineering! and I look and feel and research everything to death!

I can't get out of my head as to why NISSAN pulled HP number from NISMO and IPL to 350HP 348HP with just high flow CBE and tune.

The intakes did not change!

NISSAN has pulled everything they can out of the 3.7L setup! so why on earth do we think an aftermarket business like Stillen or Injen knows best and is able to make more HP then OEM???

If that is the case why does NISSAN pay there engineers $100 per hour to get as much HP as they car? why not just build a setup like Injen or Stillen?


I understand you want that added HP at 6500K but at WOT with OEM, I don't feel anything more or less with the Injen setup just that the Injen and Stillen are louder!!

I took apart my whole intake setup and after looking at it, it's very good design.

So why is the aftermarket setups making more HP or seem to be?

I will be getting my car dyno at Z-days to see my WHP with stock intakes and F.I CBE with tune.

This thread is still growing? Kill it. Kill it with fire

this is because aftermarket companies are TRYING to get max performance. Nissan just bumps it a but to make you pay extra money for a nismo or IPL.

aftermarket makes more power because that's the point. free up HP that OEM denies.

look at the GTR. intake, exhaust, and a tune and the thing can jump up 100AWHP just by taking away air restrictions.

you say you research this all to death but i feel like you havent. possibly just stuck on the idea OEM is better? i dont know why but you need to realize it's not :shakes head:

i'm not sure now if you're trolling or just stupid at this point.

No doubt, but if you're serious about performance gains??? The way I said it is the only way to really get it done right.:tup:

The thing is, I have seen several independent dyno graphs where long tube intakes made power across the entire power band (most of which is higher up like you mentioned, but still making 4-8 whp in the low end) When people do cbe plus lth/tp/hfc, yes the argument can be made that intakes are not needed because they will provide only small gains at that point. By themselves though, I would think adding 20 whp up top, and about 4-8 everywhere else is not too bad.

Also, Your argument is people are wasting money on something that doesn't help the car or hurts it's performance.... To be honest, isn't that what you did by buying an IPL? it's performance advantages are slim over the standard G37 but yet it costs $10,000 more.

He doesn't own an IPL.

what's the difference between an IPL and a G37 IPL performance package?

Good thing I track my car and don't lose sleep over $500-600.

I just trying to really understand why people feel they are getting more HP from aftermarket part?

How would you feel if I told you that Stillen did not do any R&D and they just took some pips and filters and design them in such a way to lean out your eng to run richer so on a dyno you see more HP? you feel pissed off right? or would you still buy it because you think in your head that if you are putting an aftermarket part on your car that it's got to be better design and NISSAN is just holding out on HP.


If you go and talk to MINES of Japan or Amuse Powerhouse! they always run stock air box with there tunes and setups!

As you can see they run stock air box with RAM Air!

Wait, how do you know that it's stock airboxes under those hoods? In both pics it's completely opaque.

you should be banned for you're stupidity. those cut outs are exactly where the filters on AFTERMARKET air intake filters sit you dumb fuck. and AFTERMARKET is PROVEN to make more HP than stock. how many times do you need to get your butthole flamed until you give up and leave.

When I got my 2011 G37, the dealer did not have a black IPL in stock. So for about $6K or so they put together IPL performance pack for me. It was ECM, Eng cover, body, rear package tray, shocks and springs, wheels would have been more.

So they installed all that for at the dealer, I was happy with that as I wanted black on black and did not care for other colors.

Also just got my car service last week and they updated my ECM and TCM for me so I have the most recent software and eng tune!

I do how ever have to get my plugs replaced at 60K and not 100K like the non IPL does.

Oh wow!! really?? I think you should do more research before you call names and show your true ignorance! :shakes head::shakes head:

Mines even makes there own high flow filters for the stock air box!

I think your just upset because you are trying to justify your intakes! :rolleyes:
