We’ve had a fair bit of rain just recently so thought wise to check that the plenum is draining OK. The last time I checked was about 3 years ago soon after getting the car and then removed the vent covers over the chamber to check. This time I shone a torch through the gaps in the vent cover and could see quite clearly that there was no build up of water …… so peace of mind.
