Looking to upgrade to bigger injectors possibly the FIC 1100cc's, I know they are High Impedence and with the 8/9's you had to remove the resistor box or something like that. For the x do we also have to remove the box or do any modifying? Or will I be fine just dropping these in?

 

The X is already high-impedence. So no, there is no resistor box to remove. I think you will still need some adaptor clips that FIC will include with the 1100's for the X's. I'm not 100% on that though.

 

Ok thanks for clearing that up, good to know. Yes there is a plug and play harness available for an extra $45.
