Product Details

The Denso Double Platinum line is engineered for vehicles that call for stable ignition performance and long service life under factory-style operating conditions. Part number 3284 uses a platinum center electrode tip paired with a platinum chip ground electrode tip to maintain consistent spark characteristics, while the copper core helps support efficient heat transfer. This design is well suited for applications such as 2000-2009 Honda S2000, 2002-2006 Acura RSX, 2007 Honda Civic, 2011 Honda Civic, and 1991-1993 Acura NSX. This part cross-references DENSO Auto Parts PK22PR-L11S for the same application.

Common Issues This Part Can Address

• Rough idle caused by worn spark plug electrodes
• Hard starting from weakened ignition performance
• Misfire conditions related to degraded spark delivery
• Reduced fuel economy from inefficient combustion
• Loss of throttle response from inconsistent ignition timing

Installation Notes and Tips

Verify the thread diameter, reach, seat type, and hex size before installation. Check the pre-gap against the vehicle service specification and inspect the ignition system for coil, wire, or connector wear before installing Denso 3284. For best results, install on a cool engine and torque to the manufacturer’s specification.
