DEI 10378 / 010378: fuel-rail and injector heat shield kit for the 1997–2004 Jeep inline-six application. Featured Wrangler fitment is 1997–2004 TJ with the 4.0L inline-six. Not for four-cylinder TJs or 2005–2006 TJ models.
The kit helps reduce radiant heat exposure around the manifold, fuel rail and injectors. Includes a manifold shield, fuel-rail cover, six injector covers and twelve injector O-rings.
Check the original fuel-rail configuration and follow the DEI installation instructions. Engine or fuel-system swaps require a separate application check. Heat shielding is not a diagnosis or guaranteed repair for fuel-system problems.
