4Pcs Iridium Platinum Spark Plugs For Jaguar X-Type 2002-2006, Ford Taurus 1999-2006 & Mercury Sable, OE ITR6F13

Iridium Platinum Spark Plugs for the X-Type, Taurus, and Sable

This is a set of 4 iridium platinum spark plugs built for the 2002-2006 Jaguar X-Type, 1999-2006 Ford Taurus, and 2001 and 2003-2005 Mercury Sable, cross-referenced to OE numbers ITR6F13 and TR6AP13. If your engine is misfiring, idling roughly, or you're noticing reduced fuel economy, these plugs replace a full set with iridium platinum construction for long service life.

Why the X-Type, Taurus, and Sable Share This Plug

The Jaguar X-Type was built on a platform closely related to the Ford Mondeo and shared its Duratec V6 engine architecture with the Ford Taurus and Mercury Sable sold in North America during the same era, even though the three vehicles were marketed under very different badges and price points. That shared Duratec engine family is why one spark plug, cross-referenced to the same OE and interchange numbers, covers a luxury sedan and two mainstream American sedans instead of needing three separate parts.

Compatibility

Fits the 2002-2006 Jaguar X-Type, 1999-2006 Ford Taurus, and 2001 and 2003-2005 Mercury Sable. Because these sedans were offered with more than one engine option across their production runs, it's worth confirming the OE number above against your specific vehicle's engine before ordering, particularly if you're unsure which V6 variant your car has.

Signs Your Spark Plugs Need Replacing

Worn spark plugs typically show up as a rough or uneven idle, an engine that hesitates or misfires under acceleration, reduced fuel economy, or a check engine light triggered by a misfire code. Because iridium platinum plugs are designed to hold their gap and firing performance far longer than standard copper plugs, a set that's finally showing these symptoms has usually covered significant mileage, and delaying replacement further tends to affect fuel economy and engine smoothness more noticeably over time, and a worn plug that's ignored long enough can eventually foul badly enough to trigger a misfire code.

Why Iridium Platinum Plugs

Iridium and platinum are harder, more heat-resistant metals than the copper used in standard spark plugs, which lets the electrode stay thinner and more precise for a stronger, more consistent spark over a much longer service interval. For a V6 engine like the Duratec used in these vehicles, consistent spark across all six cylinders matters for smooth idle and even power delivery, which is why iridium platinum plugs are a common upgrade choice even when standard copper plugs would technically still fit.

Installation Notes

Replacing spark plugs on this Duratec V6 means removing the ignition coils or coil packs to access each plug, using a spark plug socket to remove the old plugs without disturbing the surrounding coil boots, and gapping the new plugs to factory specification before installing them. Torquing each plug to spec rather than overtightening is important, since these plugs thread into the aluminum cylinder head and can strip the threads if forced. A dab of anti-seize on the threads, if not already applied to the new plugs, makes the next replacement easier down the road.
