Hey guys. Just installed my Cp-e CAI(Thanks to Ron@Whoosh). The plexiglass lid is covered in some sort of paper/adhesive combo which is a nightmare to scrape off. Out of frustration of trying to use my thumbnail as a scraper(didn't want to scratch the plexiglass), I rubbed the edge of said paper with the meaty part of my thumb and what do you know it rolled up! Took about 20 minutes and a lot of elbow(thumb)grease but it all came off. Now I can stare at my pretty Synoil filter.
