Is it really worth putting a Cold Air Intake on 370z and what HP gains

In all honesty it may be heard to feel a 5-10 hp gain, but it is still there. Plus as you slowly make it easier for the engine to breathe

In all honesty it may be heard to feel a 5-10 hp gain, but it is still there. Plus as you slowly make it easier for the engine to breathe and start gaining hp you will notice a difference. If you go from 270whp to 300whp, I bet most people would notice a difference. At the same time if you do your mods one at a time and have a bit of time between each one, I think the sensation of the amount gained wouldn't be as much as if you bolted them all on at once. Just my opinion, but it sounds like you would be happier stock. There are always sacrifices you have to make for more power, the question you need to ask yourself is whether or not you are willing to make those sacrifices.

if you look at the stillen dyno chart you will see that the engine really doesn't make any real power gains until 6500 -7000 rpm and below that range it only makes between 5-8 hp increase, not a really that significant for a $1000 price tag. Also most ppl don't drive their cars close to redline.

Well, I guess you have pretty much answered your question. In your opinion the gains aren't worth the price, although i have never seen them selling for $1k. For somebody who is looking to get every last bit of hp out of their car w/o going to some sort of forced induction, these are probably the best bet. I personally went with the drop-ins and Post-MAF tubes. Eventually, I'll step up to the stillen intakes, but it probably won't be for a while.

ooooh nice! will be checking them out.


OP: the G3s tend to give power up top + i've seen where the air to fuel is thrown off. your best bet if doing something to the intake system is a MUST then you would be best off with the drop in filters + post MAF tubes. the VQ's intake system is already efficient so squeezing more HP out of it will be hard, IMO there are other places where HP is found aka HFC's or TP's.

^^ yeah, nobody else here has run them. it was the best performing drop in filter for the Evo X, so i figured i would guinea pig them in the Z

btw, the 350Z filters fit the 370Z air box just fine. same part number.

That was the same conclusion I came to. I think the cai kits are around $500 though not $1k. Still not worth it unless you are out to try and squeeze every single possible horse you can out of the motor. And if thats the case you should be thinking turbos/supercharger...

i drove the car for the first time this morning w/ the Cosworth's. me thinks there's a slight improvement in throttle response below 3k rpm's. i'll have to check the good ol' butt dyno again this evening after work and report back

Turbo's work great when new, but after the mileage gets past 50K, they usually need replacement, due to impeller or bearing problems and even carbon build up.

They also put a lot of stress on the motor, they are good for racing apllications , but not that good for driving your car to high mileage standards.

I had an older 85 z turbo that had the turbo replaced 3 times in 40K miles, according to the original owners reciepts. I drove for about 10k and sold it.
Better to go with CUBIC INCHES or Stroking a motor as compared to turbo etc.

and also dont forget, numbers shrink a bunch once other bolt ons are added (exhaust, HFC's or TP's...)
