i replaced the OEM air box with the pop charger and z tube, i was wondering if it is possible to install the OEM air box with the z tube? do i have to modify the air box or anything? i want to do this to see if i can gain some of the low end torgue back...

 

The OEM air box fits fine with the z-tube

Fits no problem. Try removing the resonator on the bottom of the OEM air box before you re-install it for some extra growl.

sorry for sounding,, dah! what is the resonator, is that the box that plugs into the hole that you see when you remove the OEM system to replace it with an aftermarket? if you have done this, did you replace an after market CAI or went straight to the OEM and Z/k&N?

 

This is it, Just take it off of the OEM airbox. You may want to plug the hole at the bottom of the airbox once it's ben removed. Check out this thread for more info

thanks for the thread and pic....reason i want to do this is to get more low end torque, but reading the threads i've concluded that it growls better but not a better response than an aftermarket. I may be incorrect about this thoe...

 

i think the primary purpose of that is to trap large dirt particles and junk so that it doesnt get in the way of the air filter... i highly recommend not to remove this piece. although removal will make the engine sound louder, it will also make the air filter much dirtier and trap more particles, needing to clean it more often...
i have the K&N drop-in and am getting the Z-tube in 2 days, im leaving that "resonator" in...

Yeah I kept mine in... I vacumed out my stock air box because it was still full of dirt and junk... I would leave it as I do not think that any gains in sound or performance are worth it.
