Interesting discusion, last time i saw this it was on 2 pages!
My car is running perfectly and has since 5 mins after it happening, the VTEC is also kicking in normally too, just not as loud as it was via the filter!? I'm assuming this will be to do with the filter getting a bit moist and needing drying out? No idea really, just thinking outloud........ since saturday, we've had more rain, snow and freezing winds, so not much chance to dry out if that is the case!
As said, what i went through wasn't like going through a Ford, it just enough for the water to flow out of both arches etc....... low speed and not driving like a tool would have helped, what wouldn't have helped is how low my car is at the front!
