2003 Ford Crown Victoria 4.6L Plug Lifespan
Posted to Ford Driveability on 3/3/2005 29 Replies

I have almost 50 of these police cruisers and I have been asked to find a sparkplug that will last longer than the ones from the factory. I currently use Motorcraft AWSF 32P Platinum 's and get around 50K miles. Any suggestions for an upgrade?
