Re: TR- any spark-upgrade for 4.0?
I don't have any part numbers anymore. It started out as with a Ford 300 tune, with the old cap and rotor laying on my bench for a couple of months. Later, after reading about TR's upgrade, I wondered if it would also work on the 4.0. I had a '95 4.0's dist. sitting on the bench also, so I ordered an adapter. It fit. When I installed the rotor, I remember it had some kind of interferance problem. The rotor would hit the cap as I spun it. Hal, another mechanic I work with said try this rotor. It fit and worked fine. I just pulled the cap of mine and it says 8 cylinder on it. That is about all the info I have at this time. Hope this helps.
