EVALUATION SUMMARY Manufacturer Name: MAZDASPEED Performance Accessories Name of Device: Intake Systems Background: MAZDASPEED Performance Accessories (MAZDASPEED) of 27100 International Drive, Flat Rock, Michigan 48134—9400 has applied for exemption of its Intake Systems from the prohibitions in Section 27156 of the California Vehicle Code. The Intake Systems are manufactured by Advanced Engine Management, Inc. (AEM) of 2205 126" Street, Unit A, Hawthorne, California 90250, and they will be marketed by MAZDASPEED. They are designed for various 2003 through 2006 model—year Mazda passenger cars. These vehicles are subject to the following standards and regulations: 1. LEV II ULEV or higher Federal Test Procedure (FTP) exhaust emission standards 2. Supplemental Federal Test Procedure (SFTP) exhaust emission standards 3. LEV II or enhanced evaporative emission standards 4. On—Board Diagnostic II (OBD 11) System regulations Recommendation: Grant exemption to MAZDASPEED as requested and issue Executive Order D—607. Device Description: The Intake Systems in this application are similar in design and function as AEM‘s Cold Air Systems previously exempted under D—392 series Executive Orders. The system is designed to increase the vehicle‘s power output by introducing cooler air drawn from outside of the engine compartment into the engine. The system consists of an open—elementair filter (designed to be less restrictive than the stock air filter), filter sock (some systems) (slides over the air filter and is used to prevent water sprays from saturating the air filter), air intake pipes, and mounting brackets/hardware. The system replaces the stock air filter, filter housing, resonator (permanently removed), and the air inlet tube. Discussion/Basis for the Recommendation: This exemption is based on the following: 1. SFTP and OBD II System tests on a 2003 USEPA Bin 8 (ARB—equivalent ULEV) 2.0 liter Ford Focus (D—392—21) 2. SFTP and OBD I! System tests on a 2001 ULEV 2.0 liter Volkswagen Jetta (D—392—21) 3. SFTP and OBD It System tests on a 2003 LEV 3.0 liter Lexus 18300 (D—392—21) 4. Engineering evaluation of the impact on SFTP emissions The SFTP certification levels of many of the vehicles in the application are low (less than 40 percent of the standard); however, some of the vehicles have certification levels higher than 40 percent of the standard (e.g. 43 percent for NMHC+NOx and 51 percent for CO). Through testing, AEM had previously shown that its intake systems do not cause the vehicles to exceed the SFTP standards (items 1 through 3 above). These tests were conducted on vehicles with certification levels higher than those of the Mazda vehicles in this application. Based on these tests, the vehicles in this application are not expected to exceed the SFTP standards when operated with the intake systems. Testing also showed no adverse impact on the vehicles‘ OBD I1 Systems. 5. FTP and OBD II System tests on a 2006 LEV 11 ULEV 2.0 liter Mazda MX—5 (D—607) To determine the impact on FTP emissions and OBD II System, MAZDASPEED was required to conduct testing. Test results are summarized below:

(ATDS) in Ontario, California. 1 Mazda‘s NMOG/NMHC ratio of 1.04 was used to calculate NMOG. 2 HCHO/NMHC ratio was not available for the test vehicle. The ratio for a 2003 2.3 liter Mazda 6 (test group 3TKXVO2.3EJ1; ULEV) was used to calculate HCHO. A ratio of 0.016583 was used. 3 Deterioration factors (DF) for HCHO was not available for the test vehicle. The 50,000— and 100,000—mile HCHO DFs for a 2003 2.3 liter Mazda 6 (test group 3TKXVO2.3EJ1; ULEV) was used for this evaluation. The 50,000— and 100,000—mile HCHO standards for the DF vehicle are 0.008 and 0.011, respectively. 4 Mazda was allowed to state HCHO emission compliance based on historical data and did not submit any test results. Because the test vehicle is a very low—emitting vehicle and conventional CVS sampling system was used, ATDS was required to perform duplicate FTPs. NMHC and NOx emissions varied more than 20 and 50 percent, respectively; however, all deteriorated emissions were below the standards. Testing showed that FTP emissions of the modified vehicle do not exceed the applicable emission standards. Also, ATDS reported that all OBD 11 System readiness indicators set to complete with no diagnostic trouble codes when the vehicle was received for testing and at the completion of the two FTP tests. Similar results are expected when any of the intake systems are used. Based on this, MAZDASPEED‘s Intake Systems are not expected to have any adverse impact on the emissions or the OBD II Systems of any of the vehicles included in the application.
