Is cold/ cool air intake worth it?

The old version of the CAI, which you can't buy anymore, was said to provide an extremely slight benefit. The CAI you can buy today only looks good under the hood and makes more noise, no performance benefit.

 

I was just watching motorweek on axs tv, and they were comparing the mpg of the Toyota fj with and without the cold air intake and catback exhaust system. they only got .4 of a gallon increase. once you payback for the cost of the modifications it will be about 47k miles before you start saving a penny.

 

and the stock truck already has a cold air intake.

 

I would do it purely for the sound and it depends on where you live too

 

I guess it's a personal preference. The first thing I did to my '07 was a K&N cold air kit and the Borla exhaust. I wasn't going for mpg, but performance. And I love it!

 

Sound/butt dyno performace or did you actually gain real performance?



To the OP, did they do any HP tests too?

 

Awesome thing is most "cold air intakes" actually raise the temperature of the intake air.

 

CAI + snorkel >>> intake temp = outside air temp

 

Bet you mine sounds better than yours. Lol plus there is noticeable power difference. Airaid CAintake, throttle body spacer and custom cat back exhaust. Vroom vroom bitch (jesse voice)

 

A suspension lift doesn't give you any MPGS either

 

I went from a afe stage 2 si, header back exhaust and urd maf to stock and i'm happy with stock

 

Snorkels are good for something!

 

throttle body spacers are just anodized paper weights....

 

I put one on with my supercharger and it really brings out the sound of the supercharger so I would do it again just for the sound it makes

 

Funny how everyone talks shit and they are all running stock???? Makes sense to me

FYI, if lower intake temps are what you want, insulate your stock Air Intake tubing. The stock is already a "Cold Air Intake" and all that most aftermarket CAI's do is smooth out the flow path and create less air flow restrictions. Which is where you get the added noise from, and the slightly higher performances at higher RPM's due to the less restricting flow during the high RPM air flow velocities.

Though a lot of Aftermarket CAI's also suffer from engine bay heat soaking. Insulating them has positive effects as well.

Just don't be an idiot and buy the ones that suck air from IN the engine bay...

 

before i got this volant, i had home made one. welded together a filter box out of some thing gage sheet steel, and then insulated it. just had a plastic intake tube like any of the other aftermarket companies. with the insulated box, i ran 3-5 degrees cooler than the volant does in 90 degree weather. now, the snorkel on the other hand, is a trump-all it seems, getting my intake temps at or within 2 degrees of outside air temp. that's while driving of course. heats up a little sitting at idle. may wrap the intake tube for that.

 

I saw that on motorweek as well. I'd venture to say if you are trying to save penny's on gas you have the wrong vehicle. You need a bicycle. Anyone adding a CAI and trying to save money is doing it for the wrong reason.

 

exactly!

 

The only thing throttle body spacers do is make noise. It is useless in a Fuel Injected engine with a throttle body design. Older cars with carburators benifit from a tb spacer but thats about it.
