Re: WJ Jeep Interchangable parts

The external engine casing is the same for all the 4.7 engines, so hardware wise it should just fit. There can be differences in the tone ring teeth between the different models, but im not sure how this is between 99-00 and 01-02. Worst case you will need to change the PCM together.

Re: WJ Jeep Interchangable parts

Hi
What I want to do is there is a company who make Extractors or Headers for a 1999- 2000 model 4.7 and I was wondering if they will fit .
The company said only those years 1999-2000 but if the engine is the same and the body is then you would think they should fit .
