Hi alchemyx,
Short answer: I'd change the spark plug caps.
The HT leads are formed as part of the coils and so must be replaced together if that is really necessary. Commonly found on ebay for not a lot of money.
But most people find it's sufficient to just replace just the spark plug caps, and trim 0.5cm or so off the end of the existing HT leads to ensure a good connection (ensuring they'll still be long enough).
If you're familiar with the use of a multi-metre to measure resistance then you can test your existing coils (both sides), leads and caps to see if they're within spec.
It's quite simple to de-assemble and re-assemble, and you can find the resistance specifications in your haynes manual.
You'll probably find your caps have gone out of spec and should be replaced. They may even be arcing to the head when wet.
As far as water is concerned, new caps may help, but also a good spray with WD40 can't hurt either.
Hope this helps, and let us know how you get on.
Andy
