This Executive Order does not constitute any opinion as to the effect the use of the High—Lift Camshaft Set
may have on any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on the following submitted emissions test data on a 1997 Acura NSX
certified to a tier 1 emission standard:
                      NMHC       CO       NOX

Test results showed that tailpipe emissions with the High—Lift Camshaft Set installed on the vehicle met the
vehicle‘s applicable emission standard during Cold Start CVS—75 Federal Test Procedure. This Executive
Order is also based on On Board Diagnostic II (OBD 11)testing conducted on the same 1997 Acura NSX.
Test data showed that the High—Lift Camshaft Set when installed on the vehicle did not affect the vehicle‘s
ability to perform its OBD II monitoring.
