HI, Has anyone ever installed a HEI or DUI ignition in a 1989 4.2 YJ.
If so, what kind and were there any improvements in performance?

Thanks

Anybody else ever think DUI is an odd name for an ignition?

I did the HEI to my 258 in my 90YJ and love it. It's a pretty easy upgrade
and can be done in ones driveway. The jeep is now got some more "pep" and
the mileage has increased.
