here is the thing though, i already have drop-ins on my car and i dont have the sound im looking for, and as far as IATs go, the stock box will heat soak(from what i have noticed) if you're sitting there for a while but it will cool back down when you start moving, i figured the same thing will happen with SRI since the hole where the airbox sources air from will be open and cool air from the bumper will be flowing into the car once the car is moving

like i said, i am planning on supercharging my car, so really im doing this mod just for sound and looks if i decide to do it

i am honestly on the fence about this

I think it's a net negative mod. Looks bad to me cause it replaces a better intake. Try the Z1 post MAF tubes and see if your sound improves? You can hear my setup if you're around north county.

What filters do you have? What short ram intakes are they? Do you have a Nismo??

i live in north county, id love to hear your setup, i have always recommended post maf tubes and K&N Drop-ins because its cheap and they net around the same as a bunch of long tune intakes do and they are only 4-6whp

the intakes i found look like takeda sri but he had them painted dark red, im still kind of on the fence about them though

The point I was trying to make was, that if your only going to put on the aftermarket CAI , your HP returns will be only marginal and may be even less than stock , if the car hasn't been remapped or tuned properly. You also need to buy the best complete racing or street legal exhaust to fully achieve significant gains with the aftermarket CAI systems.

I would agree that the atermarket CAI would be very helpfull how a car that didn't come stock with a factory CAI , like a pick up truck etc.

But on the cars that have factory installed CAI returns, then the gains are only marginal.

This is not correct. You see the most gains from a CAI prior to any other mods.... Once you put on others, such as Exhaust, the results from a CAI are smaller than if the CAI was your only mod... Meaning, if you put on a CAI as your only mod, the HP will be around 10 - 15. If you put on an exhaust, and then later add a CAI, the gains from adding the CAI will be like 5 -6 HP or so...

There's no sense responding to him. There's nothing that will ever make him believe that there's a reason to buy a CAI. If you correct him, he'll just move the goalposts. Save the effort.

For a good laugh, read through whatever thread about radar detectors where he applied his same flawless reasoning. It makes his CAI posts look like peer reviewed white papers.

By all means, read the radar test results, overall results were that they couldn't be trusted reliably, even the high end models.

People that spend a lot of money on gimmicks that really don't work, never really want to admit they've been taken ! with the CAI and Detectors.

I'm not getting into a debate with you. You have repeatedly shown that you are unable to interpret data to form a statistically valid and meaningful conclusion devoid of your personal preexisting bias. You are free to your opinion, whatever it may be.

Marketing Gimmick - a trick or device used to attract business or attention - Webster Dictionary.

These are really just the gimmicks or fads, that the companies selling these devices, hope every new driver or new car buyer will fall for with every vehicle they buy.

To sum all of them up.

After market CAI minimal HP gains vs. cost, 370z already comes stock with good CAI intakes, cons = warranty issues, tuning issues.

Reusable oil type air filters = less filtration than cheap stock paper filter, possible dirt particle transfer during cleaning, MAS damage from excessive oil, high cost.

Radar/laser detectors, jammers = fools toys.

Bottom line is for the potential buyer to do the research on their own and take all advice, either professional, internet, friends with a grain of salt, before making any purchase.
