Just got my Whisper lid from someone on this or another forum. It was supposed to work with my '02 Z28 but it doesn't have the provision for the air tube and I don't want to just stick a filter in the stock air tube. (Why? Just because.) Consequently, I'm looking to buy an SLP lid (PN 21045) ASAP. If you've got one for sale, let me know a total with shipping to Mankato, MN 56001. Thanks!
