Ive cleaned many engines over the years so that is not my question plus I searched for my question and couldn't find anything....or I'm really blind.

Purchasing a 2007 RDX and the engine bay is nasty at best in my opinion. I plan on cleaning the engine but don't know anything about the intercooler. I'm assuming I need to take off the plastic cover and cover the fins up when hosing everything down...is this correct? I also am planning on vaccumming the fins which I found on this forum on what to do.

thank you for any info/guidance to my question. Looking forward to being part of this forum again...owned a 99 tl years ago and loved it.
