Just started tearing into ski from the winter. (2013 rxt260 riva stage 3) first thing I did was remove stock intercooler to replace with fizzle one, & I noticed alot of salty residue on both sides. SC side appears to throwing it in & throttle body side looks like dried up water spots. Pressure tested ic & no leaks wtf. Also I noticed same residue in the clear hose leaving intake manifold block off going to my boost gauge.
