Review on 🔌 AUTOLITE Iridium XP XP5263 Spark Plug, 1 Pack - Advanced Automotive Replacement by Bryan Sperling

Installed for Customer 2005 PT Cruiser 2.4L I4 @ 180,000 miles with check engine light due to rough idle / accidental misfire / poor performance. Another mechanic misdiagnosed a fuel pump failure which is a very expensive and unnecessary repair (noting here in case others get the same misdiagnosis). The original spark plugs were badly worn, with a gap of approx. 0.100 and platinum discs missing! TIP: Replace the ignition wires at the same time as the spark plugs. You will not regret it. I have used these and they work great: uxcell 671-4079 Auto Car Engine Spark Plug Wire 4pc Ignition Wire Set for Chrysler PT Cruiser Sebring Dodge 4 Cylinder 2001-2009 NOTE.
