So I been thinking I have this Weapon R Intake for my 08 intake and thinking in putting it in my xB is an 08 Intake and I looked at the pics from Weapon R and compare the too.
And saw a little diff. the air hose is lower the the tC and the senor is the same place. the air filter will be seating like this (L>)and not (J) the air filter will be pointed to the front of the car.

 

from what i recall none of the tc intakes have ever bolted straight on. i feel you would be better selling that and getting a tenzo intake for the xb and a new filter if u like. works amazingly well

 

i dont like the cai i prefer short ram and i have been lookin and nothing

 

tenzo r ftw

 

I just finished making all my mod in my 2011 Scion xB RS 0.8 I have an Airaid Throttle Body Spacer, Typhoon K&N Short Ram and a Single Rear Borla Exhaust. And I must said that I love all the combo, the throttle pedal feels light, and the rumble of the engine is just perfect not that laud like others that make you car and yourself ridiculous this is very seduce but the button line is the I gain more power and save gas.
