Autobahn Spark Plug - Sebo Walker A quick Spark Plug with Sebo Walker to celebrate the release of his full part that came out today! If you haven't seen it go to www.commonwealthstacks.com or here vimeo.com and check it out! The Spark Plug is a typical day with Sebo at Stoner Plaza in LA. In fact, this was filmed yesterday! His typical days are a little nutty. Thanks Noah for filming! Funny how brocam is now an HD dlsr.
