I have been reading the altima forums, and people claim to enojoy the WAI for their car. Im just wondering if its available for this car, and is it really worth getting?

 

WAI?? Umm are you sure not a CAI? Cold Air intake or i could be wrong since i havent heard of WAI. Dunno. Any 1 know what it is?

Its supposed to outperform cold air intake. someone claimed to get 13 hp off of it.

 

Short answer - yes, the popcharger and stillen airbox are versions of a WAI.

WAI/CAI has been debated numerous times...I personally have noticed more gains with my Stillen Air Box than with the Nismo CAI that I put on my Z...but these are two different cars with different aerodynamics...

WAI may actually pull cooler air than CAIs...the argument is that the air is hotter close to the ground because of the heat absorbed by the road. WAI may have faster throttle response as well and it is said that the stock airbox location on our cars is an area of high pressure, so the air can more freely enter the intake. But again, this has been discussed before so a search might be helpful...

 

Regarding 13 hp, maybe on an Altima but unlikely on a G. I would expect gains in the low to mid single digits but without a wind tunnel, dynos testing intakes aren't accurate.

 

I don't know why you would call the Stillen HiFlow AirBox a WAI.
It pulls in air from the same place as the stock box does. Indeed
it is open at the front, but when driving, any engine heat will not
be getting sucked in.

Technically you're right, I just always considered WAI the same as a short CAI. But if we're being technical, you can't say "any engine heat"...some will always get in. But I'd think the Stillen would suck in air of the same or slightly warmer temp than the stock airbox since the bottom is open (it will just suck more of it)...or not?

Either way, I think Stillen or Popcharger (and Z tube) is the way to go.

 

I see... thanks much.

 

Hmm, so the Injen isnt as good as the Stillen air box or pop charger Z tube? Injen claims 14.2 hp to the wheels and 12 lb ft of torque with a dyno sheet on websites but i dunno. Havent seen that from still air box or pop charger.

I've got the K&N Typhoon, which gives you 2 choices of settup.
This is the WAI settup:

The full length gives better performance, but renders a slightly rougher idle.

I have heard that CAI's are designed to perform on the dyno but not necessarily in real world situations. ie. on the road.
just what i heard, take it with a grain of salt.
