Acura RDX Spark Plug - NGK Ruthenium HX ('07-'12) is a direct-fit replacement designed for RDX models from 2007 through 2012. These NGK Ruthenium HX plugs use advanced tip geometry to deliver high ignitability and reliable operation for modern engines.

Engineered from NGK's OE-derived technology, the Ruthenium HX features a ruthenium center electrode and specialized tip designs (DFE and PSPE) that improve ignition consistency. That results in a more complete fuel burn which can produce crisper throttle response, a steadier idle and improved cold-start performance compared with older-style plugs. The ruthenium material offers strong electrode durability suited to longer service intervals on compatible engines. These plugs are recommended for vehicles that originally use PSPE-type OE spark plugs.

Features

• Patented ruthenium tip technology for high ignitability
• OE-style DFE and PSPE tip designs for consistent spark
• Improved combustion for better throttle response and idle
• Durable ruthenium center electrode for extended service life
• Direct fit for Acura RDX 2007–2012 models
