The next NASCAR release from Press Pass, Wheels Main Event, might shock a few lucky collectors with a very unique collectible hidden inside 20-pack hobby boxes. Select hobby boxes of Wheels Main Event will include an authentic race-used Bosch spark plug, along with a certificate of authenticity identifying which driver and race the spark plug came from. Eight Bosch spark plugs from Jeff Gordon’s victory at Texas Motor Speedway in April can be found in the program in addition to race-used Bosch spark plugs from Dale Earnhardt Jr., Mark Martin, Jimmie Johnson and more. Each Bosch spark plug will have a number (1-8) that is hand-written by the team to indicate which cylinder the spark plug came from.

These unique collectibles are found exclusively in hobby boxes of 2009 Wheel Main Event, which releases Sept. 30. Hobby boxes will also contain one NASCAR driver autograph, plus two memorabilia cards. Boxes may also include a bonus professional poker player autograph. In addition to the classic double and triple driver-worn pit cap cards, the memorabilia lineup includes the first-ever race-used pit wall banner, wheel cover and pit stacker cards, as well as oversized patch-edition pit cap cards. Also making a comeback are authentic Earnhardt Jr. race-used lug nut cards featuring slices of lug nuts from his No. 88 Amp/National Guard Chevrolet.
