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

Strangler · 01-26-2012, 03:03 PM

Does anyone that has an aftermarket intake have any "Bogging" problems so far?

with all the money i put into my Z

CAI, Long tube headers, the G3 CAI, 4.08 final drive, uprev tune... costing me close to 4k id imagine, i wish i didnt spend a penny and purchased a SCer or Turbo, I would of still had the car...

but if you are modding it, i say test pipes and tune are the two things that help the most

Yea, but those mods will cost way more than 4 grand total...

That's why I did my brakes first. Now I'm about to do oil cooler and I'm trying to find a good brake duct diy till something solid comes through... the next major will be all to the suspension mod hopefully will be exhaust and TT kit.

These are just performance mods and don't reflect stereo, possible bodykit? and JDM exterior mods.

I agree, both SC and TT cost way more than 4k. What happened to your Z and why would having FI cause you to still have it?

iirc, he sold it and got a 135i, so easier to pull whp out of a factory FI'd car.

So much easier to squeeze out HP per dollar on a factory FI'd car than it is with a N/A car.

I remember back when I had my GTI VR6, a CAI/CBE/tune would only net me 25hp but the guys with the GTI 1.8 Turbo's with the same mods would be pulling in over 50hp.

Logic would tell you the 5700cc engine would need the airfilter replaced sooner than the 1000cc engine.

Not necessarily true.

In order to take full advantage of the mods.

Also, not true.

We get it. You don't like aftermarket intakes. You don't think they make enough power. You drove motorcycles. Your warranty will get blowed up if you get an intake. Yeesh! If you don't want one don't buy one.

Sidenote: I also agree that it seems you are trying to force your opinion on others. And you are stating a lot of opinion as fact which is terribly annoying.

The first thing I put into my Z was the pop charger from Jim Wolf. I definitely noticed a difference. I have no idea how much gain I may have received as I have not had it on a dyno yet. But the smoother acceleration itself was a noticeable difference. I have ordered the HFC+ DBE from Fast Intentions, once that's installed, I'll have it dynoed and really see the diff.

THANK YOU, I was reading this trying to figure out why the OP was asking "are aftermarket intakes worth it?" and then spelling out 3 reasons why they are not worth it.

I would read his post and go back to the first page to make sure he was the same guy asking the forums opinion!!!

One thing a lot of ppl. don't know about these external air filter systems is that while they do flow more air they also tend to let more dirt into your engine. I come from a sport bike background and early sports cars for 30yrs.

What we found out about oiled air filters is that while they may work good when new, after about a year of use on the vehicle they became very dirty and when we cleaned them, we were never able to get them completely clean. What we found was that there was a lot of dirt or grit inside the air filter and we were never able to get rid of it.

If we reinstalled the oiled air filter this dirt would have been sucked directly into the engine. Note we correctly cleaned it from the inside out, as not to allow any dirt into the inside of the air filter.

To play it safe we went back to a stock disposable paper airfilter element.

What a lot of ppl. forget is that the airfilter is meant to protect the engine from dirt and its best to install a new airfilter every few thousands of miles.

Another interesting note is that the use of external air filters style on sport bikes were abandoned, about 15yrs. ago after it was found that they really didn't provide any real hp gains over use of the stock air box and filter.

This was due to the fact that big 4 jap bike manufactures put so much design effort into the tunned intake air tracks on most sport bikes, that most after market air filters actually reduced HP when used.

While a lot of ppl still buy these external and internal oiled filter types on sport bikes, they do so because they really don't know how they work in real life driving environment.

if i am reading that correctly, you already have your personal data from 30 years on bikes and early sports cars to make a decision.

Just have a quick question, anyone with the CAI installed can tell how it effects the mpg?

Should not effect MPG except, they sound so cool that you may start wasting gas just to hear the engine note.
