Hi all. Am new here. Just recently bought a 2015 mdx elite with 7/160000 Acura plus. Mine doesn't have running boards and stealership is asking 1050+tax for having it installed. After market is available for $400 installed. If I for for this would it void my warranty. Aftermarket sales guy asked me to check with Acura. When I called dealership they didn't give me a straight answer.
