I have driven many times during heavy rain, it fine.
Yup, my vent is Kenari vent, but it looks like the new Subaru WRX vent:regular_smile:
You will have look at the position of your extractor, make sure the rain water will not drop onto your hot extractor. Mine is just above the radiator & extractor is slightly behind.
When the car move, the rain water wont drop down as the wind from the front grill will blow it thru the vent together with the hot air. The worry is when the car is stop, the rain water may drop onto your extractor. So, check your extractor position before you install the vent.
The vent really help as I can feel the hot air coming out from the vent. Even a short distance driving after cold start, the air from the engine bay is very hot. The vent will help reduce the heat in the engine bay:regular_smile:
BTW, I'm staying in Labuan, regular go to KK. Next week I'll in KK & Kota Belud with my Focus. But now have to very carefull when taking ferry to mainland... my new skirting is quite low
cheers:X-:
