i was washing my car at one of those self car wash were u spray it down yourself...well for some reason i forgot i had a cold air intake and i accidently sprayed filter...now my car has a CEL...

 

nice, get a new filter

 

i thought so...do you know the size of the aem filter for rx8

 

unless you completely tore up the filter you should just be able to let it dry.

 

You probably sucked in a little bit of moisture from the filter into the MAF meter, thus causing the CEL. As nuke said, remove the filter and let it air dry for a while and reinstall. The CEL should go away.

Edit: I guess you don't necessarily have to remove the filter, but I would think it would dry quicker by removing it and sitting it in direct sunlight or something.
