I can't get out of my head as to why NISSAN was about to get the NISMO and IPL to 350HP 348HP with just high flow CBH 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 casey 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 add 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.

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.

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.

Its true that Nissan probably has the best design intake and exhaust combo , as on the Nismo, most of it is a marketing ploy to get you to shell out the extra $8K for the Nismo over the base model.

Nissan could have put the same parts on the base model, then no one buys the Nismo.

Nissan's hands are also tied by the EPA regs. Aftermarket companies offer their exhausts and intakes with the usual disclaimer that they are for off road use only or track use.

So the aftermarket companies can pull a few extra hp with open flow thru systems.

If you have an out of warranty Z or bought a used one out of warranty , you could play around a lot with the exhaust and intake system and not really worry about anything.

But with a new car under warranty, I wouldn't want to run the risk of voiding the warranty or having to store an old exhaust system and intake system , that I would have to reinstall if I have to take the car in for a warranty related issue. Its simply not worth the BS.

It also depends what you are taking the car in for warranty work !

Lets says its an engine failure or some other serious repair issue, I wouldn't want to risk them voiding the warranty , due to the mods.

The other issue is that you throw away a lot of cash that on these parts for very little HP increase, and in 3-4 yrs. you sell the car and all the extra parts you put into it do nothing to increase the resale value and in most cases a highly modded car is worth less at resale or trade in time.

that's why we remove the Mine's rear spoiler when we take in for engine failure, just to be safe!

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.
