Unlike the 7/8/9 (CT9A) Evos, the 4/5/6 (CN9A/CP9A) have the locations of their airbox and battery swapped (the battery is in front of the airbox). A lot of what I have read here and elsewhere says it's not worth it to replace the airbox, but I'm assuming this really only applies to the 7/8/9? To me it seems like a no brainer to want to move the airbox to the front on the 4/5/6, which has the added benefit of shortening and streamlining the intake pipe.

Anyone have experience or data on this?

Any 4/5/6 owners who have relocated their intake to the front have recommendations? I'm currently looking at the Laile kit that lets you retain your MAF and wondering if the STM 4.5" will fit it.
