Do you have a track car with no catalytic converter, or have you changed your OEM catalytic converter to a high-flow version?  Both of these circumstances can result in a dash "Check Engine Light" (CEL) indicating a failure of the catalytic converter system.

O2 Sensor Spacer    |    MadMax DV
MadMax DV

Developed and Manufactured by SCCA racer Max Clesca

The MadMax DV was created created out of the desire for a valve capable of holding 30-35 psi steady when racing the 1.8t powered Audi TT. The valve also had to hold "big boost" while retaining stock drivability, response and stay maintenance free.
