Intercooler cleanup frequency often depend on engine oil level, if the engine oil level is to high, the oil blowby will tend to get the intercooler dirty, keeping the oil level just above the add mark will keep you from cleaning the intercooler
after 100 hrs and fooging the supercharger frequently, i pull the supercharger for cleanup, suprised, there was no oil sludge at all on the inside finns
My second 300x, i brought it to dealer of oil change, they put in half a quart to much and after a few ride the intercooler was full of sludge.

370+hrs in total. Pictures about was just taken about three weeks ago. At that time I had 179 hrs of run time prior to the last time I pulled and cleaned intercooler. That was at 174hr(first time). I use go ole WD-40 since we owed the ski. Spray after anytime we ride brackish & saltwater trips! Spray while motor is running hooked to hose for 10-15 seconds. This go around the intercooler looked better then the first time. Neither time the fins didn’t have any real gunk are film buildup to speak of. Ski is used 75-80% in brackish/saltwater environments. I greased the idle pulley assembly tensioner bushing during those times as well.
