Dorman : 674-497
Artikelnr: DOR674-497
The original equipment exhaust manifolds on certain Jeep Wagoneer SUVs and Ram 1500 trucks are equipped with a cylinder deactivation system that shuts down four of the engine's eight cylinders during highway driving to improve fuel economy. This system causes two of the cylinder ports to cool while two remain hot, stressing the exhaust manifold to the point of warping or cracking. Eliminate potential cracking issues with this Dorman OE Fix exhaust manifold. This upgraded design features an integrated upper flange that strengthens the sides of the manifold, a thicker lower flange, and a ceramic coating that provides uniform heat distribution. This precision-engineered manifold is designed to seamlessly replace the original equipment left-side manifold on specified vehicles.
Sedan 1918 har Dorman varit bilmarknadens banbrytande problemlösare vad gäller bildelar. Dorman har släppt tusentals delar och komponenter som man en gång kunde köpa över disk från originaltillverkaren. Genom att Dorman alltid förnyat sig har de sett till så att eftermarknaden getts fler möjligheter att renovera och reparera sina bilar.
