(Page 1 of 2) State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—333—2 Relating to Exemptions Under Section 27156 of the Vehicle Code LINGENFELTER PERFORMANCE ENGINEERING, INC.‘S LINGENFELTER 350 CID LT—5 ZR1 ENGINE PACKAGE Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the Vehicle Code; and Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the Health and Safety Code and Executive Order G—45—5; IT IS ORDERED AND RESOLVED: That the installation of the Lingenfelter 350 CID LT—5 ZR1 Engine Package manufactured by Lingenfelter Performance Engineering, Inc. {Lingenfelter) of 1557 Winchester Road, Decatur, Indiana 4§733, has been found not to reduce the effectiveness of the applicable vehicle polliution control system and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1990—1994 model year Corvettes equipped with a 5.7L LT—5 ZR1 gasoline engine. The Lingenfelter 350 CID LT—5 ZRl Engine Package uses new pistons, connecting rods, after catalyst exhaust system, and reworked cylinder heads, intake manifold, intake runners, and PROM chip. This Executive Order is valid provided that the installation of the Lingenfelter 350 CID LT—5 ZR1 Engine Package is conducted by Lingenfelter and no changes are made to the stock tune—up specifications. Changes made to the design or operating conditions of the Lingenfelter 350 CID LT—5 ZR1 Engine Package, as exempt by the ARB, which may adversely affect the performance of a vehicle‘s pollution control system shall invalidate this Executive Order. Marketing of the Lingenfelter 350 CID LT—5 ZRl Engine Package using any identification other than that shown in this Executive Order or marketing of the Lingenfelter 350 CID LT—5 ZR1l Engine Package for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the ARB. This Executive Order does not constitute any opinion as to the effect the Lingenfelter 350 CID LT—5 ZRl Engine Package may have on any warranty either expressed or implied by the vehicle manufacturer. This Executive Order is granted based on results from emissions tests conducted in accordance with Cold—Start CVS—75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to believe that use of the Lingenfelter 350 CID LT—5 ZR1 Engine Package may adversely affect emissions of motor vehicles when operating under conditions outside the parameters of the previously prescribed test procedures. Accordingly, the

Lingenfelter . EXECUTIVE ORDER D—333—2 (Page 2 of 2) ARB reserves the right to conduct additional emission tests, in the future, as such tests are developed, that will more adequately measure emissions from all cycle phases. If such test results demonstrate that the Lingenfelter 350 CID LT—5 ZR1 Engine Packages adversely affect emissions during off—cycle conditions (defined as those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive Order shall be effectively rescinded as of the date the test results are validated. Further, if such test results or other evidence provides the ARB with reason to suspect that the Lingenfelter 350 CID LT—5 ZR1 Engine Packages will affect the durability of the emission control system, Lingenfelter shall be required to submit durability data to show that the durability of the vehicle emission control system is not, in fact, gffeg§$qtand/or that the add—on or modified part demonstrates adequate urability. — In addition to the foregoing, the ARB reserves the right in the future to review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures ofTitle 13, California Code of Regulations, Section 2222, et seq. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF LINGENFELTER PERFORMANCE ENGINEERING, INC.‘S LINGENFELTER 350 CID LT—5 ZRl ENGINE PACKAGE. No claim of any kind, such as "Approved by the Air Resources Board" may be made with respect to the action taken herein in any advertising or other oral or written communication. Violation of any of the above conditions shall be grounds for revocation of this order. The order may be revoked only after ten day written notice of intention to revoke the order, in which period the holder of the order may request in writing a hearing to contest the proposed revocation. If a hearing is requested, it shall be held within ten days of receipt of the request and the order may not be revoked until a determination after hearing that grounds for revocation exist.
