NGK is OEM for 2000 and 2001. The change from Champion is related to the new coil-on-plug system that fires a waste spark.

$0.50?! Nice! I think the NGKs just last longer on the coilpack engines.
What year/engine is his Wrangler? On the 4.0 many have tried the E3 and have watched them fail. Waste of cash on the XJs. Better spent on a fuel additive, lol.
