hey guys.. got something to ask.. if i just wanto try removing de U-shape piping b4 de air filter box. how to do it ah? need to remove de battery 1st?

izzit possible to replace de U-shaped pipe with a flexible hose as CAI leaving de filter box standard? if can wat size of de hose i can fit in?

you need to remove the battery to unscrew the 2 screws for the U-shape piping...
then you can take out the U-shape piping through the mud flap...don't know the exact name...
for me, i didn't take out my tyre...just turn the steering to the left side :P

sharing some info..... :D ..........

For everyone that swears that a CAI is not worth while on our cars and that the stock airbox can supply enough air needed, I did a test. I have the EVO CAI and I wanted to try out my modfied airbox. I shaved the top of the box, cleared the bottom of it, added a 3.5" expensive hose to the box from the front of the car, and added an ITG. Well guess what, it pounded the EVO into the ground like a fence stake. No more EVO for me. I am only going to show the airmass but the hp is higher as well, by 3 - 5 hp over the EVO from a block 120.

Stock Box w/ stock filter, smoothed inners = 172 g/s
Stock Box w/ stock filter, smoothed inners, ram hose = 177 g/s
EVO CAI = 178 g/s
Stock Box w/ ITG, smoothed inners, ram hose = 184 g/s

just my opinion,

don't use knn or the hks (mushroom) filter. use the apexi power intake.

ok knn u need to maintain, hks also need maintainence, and it isn't exactly cheap. whereas the apexi one, all u have to do is at every service just blow high pressure air into the filter and it's good to go again! (it cannot come in contact with water or else ur screwed!)

ok, filteration quality, hks is THE WORST! meant for really track cars or if u hardly use ur car as a daily driver. apexi has better filteration quality than the knn one because, apexi is not oil based and does not need the oil to help in trapping the dirt while sucking in air.

bottom line, go for the apexi power intake.

i felt the difference, not only in a nicer growl from my engine but my 0-100km/h time improved by 4.3 seconds! if that isn't good...i don't know what is.

oh and also, don't buy those 6" open pods for ur car cause u MIGHT feel a slight lag...just like turbo haha. cause ur engine is not that capable of sucking in HUGE ammounts of air at a time.

hope this helps. i'd be glad to answer anymore questions on this filter :)

Did u say u got 4.3 seconds off your 0-100km/h time? Wow! What car do u drive by the way?

Guys,

very useful info, anyone has any ideas about improving the stock Gen2 airbox? so far the stock airbox has a trunk that extends all the way to the front, (same like waja) only think is that it still need a decent amount of air volume, so i'm thinking of opening some holes at the back of the airbox, but i'm only affraid that it will suck in hotair, thinking of opening 50cent size holes..any comments?
