One of our cars is a V8 2002 Jeep Grand Cherokee, with all the toss pot extras except the sun roof.
Purchased the car at the Auctions for about a third of the market value, purchased at 78,000 km, today, at 145,000 km changed the Iridium plugs, mainly due to a No2 Cylinder Misfire engine warning from the OBD.
Here is what 145,000 KM old Iridium looks like, I'm f'ing impressed ( it was still working ).
The gap is over .080 ", the CDI must really crank out a spark.
