I am currently rebuilding my 1984 3.2 L engine due to a broken #6 intake rocker arm. The spark plugs that were in the engine for the last 10 years or so are the bosch super w6dc. They worked very well and look fine.

I have made changes to the engine ...I replaced the USA Pistons with the Eurostyle ... and I have replaced the stock camshafts with the WebCam 20/21 profile timed at 2.05 mm at TDC overlap.... I have a stock ignition system. My compression ratio is now supposedly 10.3. Up from the 9.5 compression ratio previously


I have noticed that the Bosch W6 DC spark plugs are not readily available. Some British eBay sites have them but not our host pelican parts.

I really don't have much experience with various spark plugs....I want to stay with the Bosch brand And copper....what spark plug would you use in my situation considering I upgraded the compression ratio?

thank you
