Enhanced Performance: Introducing the Dorman 598-136 EGR Tube Review

fits my 2003 Ford F-150 4.6 as OEM. You will likely need a new EGR fitting if you are replacing this pipe since you are replacing the exhaust manifold. The coupling is screwed into the exhaust manifold and is usually so corroded that it cannot be reused.

When I bought it with both left and right hand exhaust manifolds I was a bit concerned if all of those parts would fit. Everything was perfect. Many thanks to Revain and Dorman for providing these parts. All parts arrived within a week.

fit was a little finicky but works well and is a lot cheaper than my local suppliers of the same brand. On the other hand I had to get a fitting that went into the header itself as ours had the threads reversed and I had to make a die out of the front axle nut to rebuild it.
