I'm pretty certain the X's is a bit bigger...I had a heck of a time trying to get the RA's LICP/coupler to fit the X IC before I decided to go with the X LICP.

 

We have had a couple customers install our Evo X intercooler on the RA with no problems. The inlet and outlet are both 2.5"

We provide two silicone hoses that fit over the intercooler and stock piping.

Any questions, let us know!

Thanks,

Michael
