High Performance.

The Iridium IX plugs from NGK will provide improved throttle response, fuel efficiency, lower emissions, and will reduce fouling.

And as an added bonus the Iridium IX plug features Trivalent Metal Plating for its superior anti-corrosion and anti-seizing properties.
Application. This set of six (6) NGK Iridium IX Spark Plugs are specifically designed as a direct fit replacement for the 2005-2009 V6 Mustangs.
