In April 2007, DENSO (TAIWAN) had an exhibition on DENSO Iridium Power spark plugs with cooperation by a Taiwan racing team, the AMERICAN Car Team, which DENSO sponsors.
In the exhibition, fans had a chance to ride in the team's racing car as well as a photo session with the drivers.

Through sponsorship to the racing team, DENSO promotes Iridium Power Spark Plugs in the Taiwan market.
