yes MAYBE. Most of the time, platinums are a good choice for most engines. HOWEVER, you must realize that most of them don't list their heat range, and they are not exact replacements, in terms of heat range and depth.
So, make sure that you get plugs with the same length of thread, and with a similar heat range. Platinums can really mess up your firing and performance if not correct for your engine and application, and can even *cause* detonation or other problems. A good quality set of normal plugs is often best!
