The Bully Dog 85151 Exhaust Manifold Gasket Kit is a direct replacement for the manifold gaskets on your 2004-2014 14.9L Cummins ISX. The Bully Dog gaskets feature a reinforced graphite design with a stainless steel inner eyelet that prevents exhaust blow by. This increases the overall strength of the gasket while preventing high velocity erosion. The reinforced graphite allows for compression to provide a strong, constant seal between mating surfaces, while still being able to withstand high temperatures. The exhaust manifold gaskets are designed so they can be swapped without completely removing your exhaust manifold.
