Product Details

The Denso Double Platinum line is engineered for drivers who want an OE-replacement spark plug with durable electrode materials and consistent ignition characteristics. Part number 3273 is a direct service option for many turbo and naturally aspirated import engines, including select Audi R8, Audi A4, Audi Q5, Volkswagen Tiguan, and Honda Civic applications. This part cross-references DENSO Auto Parts PK22PR8 for the same application.

With a platinum center electrode and platinum chip ground design, this spark plug is built to maintain firing stability over extended service intervals while supporting clean combustion and reliable cold starts. The specified heat range, thread size, and flat seat design help ensure proper fitment where the OE application calls for these dimensions.
