The DEI Fuel Rail & Injector Cover Kit is a complete heat protection solution for 1997–2004 Jeep 4.0L inline-six engines, addressing vapor lock and heat soak—especially at the vulnerable #3 injector. The kit uses an 8mm thermal barrier compressed between dual reflective aluminum layers to block radiant heat and includes a precision-fit manifold shield, one fuel rail cover, six injector covers and twelve OE replacement Viton O-rings for a full installation that reduces fuel temperatures and helps restore consistent fuel delivery.
