This Executive Order is based on previously submitted emissions test data conducted by Trick Flow Specialties on a 1996 Ford Bronceo with a 5.8L engine. Test results showed that exhaust emissions with Twisted Wedge cylinder heads installed on the vehicle met the vehicle‘s applicable emission standard during a Cold—Start CVS—75 Federal Test Procedure and On—Board Diagnostic II System tests. If evidence provides the Air Resources Board with reasons to suspect that the Twisted Wedge Street Cylinder Heads will affect the durability of the emission control system, Trick Flow Specialties shall be required to submit durability data to show that the durability of the vehicle emission control system is not, in fact, affected and/or that the add—on or modified parts demonstrate adequate durability. This Executive Order is valid provided that installation instructions for the Twisted Wedge Street Cylinder Heads do not recommend tuning the vehicles to specifications different from those of the vehicle manufacturer. Changes made to the design or operating conditions of the Twisted Wedge Street Cylinder Heads, as exempt by the Air Resources Board, which adversely affect the performance of the vehicles‘ emission control system, shall invalidate this Executive Order.

_2 Marketing of the Twisted Wedge Street Cylinder Heads using identification other than that shown in this Executive Order or for an application other than that listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. Exemption of the Twisted Wedge Street Cylinder Heads shall not be construed as exemption to sell, offer for sale, or advertise any component of the system as an individual device. This Executive Order shall not apply to any Twisted Wedge Street Cylinder Heads advertised, offered for sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an ultimate purchaser. This Executive Order does not constitute any opinion as to the effect the use of the Twisted Wedge Street Cylinder Heads may have on any warranty either expressed or implied by the vehicle manufacturer. 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. In addition to the foregoing, the Air Resources Board 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 of California Code of Regulations, Title 13, Section 2222, et seq.
