IMO the purpose is only to shield the sound and heat from the engine which i dont need in fact would be better if the heat gets dissipate faster through the hood and if my car sounds louder! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />. would appreciate your comments before i proceed. thx...</p></blockquote><p></p>
