I recently replaced my spark plugs in my 2004 cavalier. I used the
Bosch ones with the 2 little points, is this adviseable or should I
change them to the regular one point ones?

On most vehicles the Bosch Platinum-2s work fine. There are a few
applications where people report trouble with them, but unless you start
to have misfiring problems I wouldn't worry about it.

In the future I would buy NGK or Denso Iridium plugs and change them
every 50,000 miles. An excellent no worry product if a bit pricy.
AC-Delco Iridiums are often in fact one of these in a blue box. They are
specified to 100,000 miles in most applications, but I am conservative
about maintenance intervals.
