i tried searching for the answer, i kno ima get flamed but wat intakes fit under the jun-tw front tower bar..
i know joez does but ne thing else..f-sport? fujita? i know injen doesnt

 

I know Joe-Z, F-sport and K&N will fit
Injen fits too,,you just gotta relocate your intake pipe a little bit,,(a little twist )

correct me if I'm wrong...

 

...Jonjon, I'm using the K&N typhoon system with my bar on a IS350.
I did have to make just a slight twist adjustment and point the tube down a little bit but not that much...but it works fine.
Just as Kenny sayz^^^^^^^^just a little twist and a top shelf vodka..hehe

 

john jonh, would you like to purchase my K&N intake?
