- You're stretching the concept a little too much! Even if water was
- to form due to "catalytic" action the cylinder temperature would not
- allow it to condense out.
-
- Also in your related post about the Splitfire plugs. The change in
- the O2 sensor can completely mask the improvements in emission levels
- and performance you see. I would be more interested in seeing the
- same data before and after the plugs where changed ( with both
- Platinum and Splitfires). New properly gapped ANYplugs will always
- give better initial performance with worn old OTHERplugs.

- Sorry, your experience does not qualify as a scientific experiment:-)
