I AM CHANGING THE PLUGS IN MY 2000 502, I WAS TOLD THAT BOSCH PLATINUM 4 PLUGS (NAPA # 4419) ARE THE CORRECT PLUG FOR MY ENGINE. IS THIS TRUE? ANY HELP WOULD BE APPECIATED.

Hi Webby, I use that part number in my Small Block. Not sure if it's the right number for the Big Block.

502 Spark Plugs

Webby,

The correct number of the Bosch Platinum +4 for the 502 is #4479. I have run them in my last two 502's and I am running them in my current 502.

Have fun!

I just love these plugs in my small block stroker. Don't understand why anyone runs anything other than platinum. Last almost forever and perform perfectly. No gapping needed. Great!
