These attach to the front of the cowl, each using the two of the “factory” plastic clips that fasten the cowl to the firewall. Made of the same durable, OEM grade heat resistant material to perfectly match other factory under hood components. Special Note: *To fit GT500 models, some hand trimming is require to provide clearance around the throttle body, otherwise it fits perfectly. Proudly Manufactured in the USA by CPC
