Champion Copper Plus Small Engine 905 Spark Plug (Carton of 1) - RA4HC for 1987-2010 Ferrari 348 Spider, Ferrari 550 Maranello and Ferrari 612 Scaglietti

Have no idea why these are so hard to come by on the market, work better than top selling brand

They did not work in my motorcycle. As soon as I installed them the bike would not run correctly. It was very difficult to start and the bike would sputter and backfire until the bike completely warmed up. Even then it would hesitate on take offs. I reinstalled the old spark plugs and it was working perfectly again. Amazon vehicle garage claimed this fit My 2001 Kawasaki Vulcan 500 but they just did not get the job done.

I run these in my Ducati Monster after trying about 4 premium (very expensive) spark plugs. These don't work any better but just as good and only cost a few bucks rather than $10 or whatever. I change them every other oil change.

Lesson learned...Nothing works better then these in my Ducati.I wasted my time and money with a different brand.That's probably why Champion plugs are factory installed.

This tool is well designed and gets the job done. Much cheaper than the OEM tool. blah blah blah blah.

fits my ducati
