No need to buy a replacement and get it specially coated. This manifold comes with a specialized ceramic coating that more evenly distributes heat, both helping to prevent thermal cracking as well as enabling smoother exhaust gas flow.

Ceramic Coated Exhaust Manifold Kit 674-695XD Features:

• Fits 2005-2014 Ford Expedition; 2004-2010 Ford F-150; 2004-2010 Ford Lobo; 2010 Lincoln Mark LT; 2006-2008 Lincoln; 2005-2014 Lincoln Navigator
• Premium replacement — this exhaust manifold features a specialized ceramic coating designed to improve durability and performance on select vehicles
• Reduces future failures — by evenly distributing heat, coating reduces uneven hot and cold spots that lead to cracks, and decreases inconsistent expanding and contracting that leads to gasket failures
• Optimizes performance — made to smooth the interior manifold surface and keep heat within the manifold, leading to higher exhaust velocity and optimal operation
• Improves appearance — coating is highly corrosion-resistant, maintaining like-new appearance for years while other cast manifolds show significant unsightly rust
