The DEI Ultra 47 T4 Turbo Shield (shield only) uses a tri-layer construction with an aluminum-impregnated outer shell, a high-temperature insulating core and a silica glass liner to reduce underhood heat and improve turbo spool. Double-stitched seams and capped anchor points increase durability. The shield helps raise exhaust gas velocity for quicker spool and is offered in T3 and T4 sizes for common turbo applications.
