Well Im about to get a EVO X IC and BOV. The intercooler does not come with pipes, I want to verify exactly what I would need for the swap.

I know that the stock lower pipe fits but what size couplers would i need? Also, I've read that any Evo X upper pipe fits, what else would i need to purchase? Is the BOV a straight swap?

 

You'll need the EvoX sized couplers. Dunno the size off the top of my head. But the OEM EvoX couplers fit (it's what I used).

the BPV is a direct swap if you keep the RA OEM LICP

 

LICP is 2" to 2.5" coupler

When I purchased my Evo X UICP and LICP from UR, they came with the couplers I needed.
