Cold Air Intake installation for 07 Barina

[Troy]

Just installed the new filter. Took it for a quick drive and noticed a good difference. But will have to remove the muffler bit you guys were on about another time.

Here we go....

I thought a CAI went in front of the radiator??

Your prices seem highly inflated, what is the exchange rate?

You will have a slight difference with the k&n, but the filter is not the most restrictive part of the intake. The most restrictive part of the intake is the muffler in the fender well. The pipe has a Y where the air surges past itself for noise cancel that is only @1.5 inches (37mm?)

OK, so for when I'm ready to do this, can I get a how-to for this job?

There is a big box in your passenger fender well that can be accessed through the panel in front of your wheel. This box connects to the airbox under your hood. Open that panel, unbolt the box, then throw the box in the corner of your garage for the next six years. You'll see a bit more power, and suffer a bit more intake noise.

tapeworn_george already explained it.
