On snorkel itself: very good overall quality, easy to fit, fits snugly to the wing and roof, and has a perfect line around the windscreen side. Generates almost no noise from the wind, it’s aerodynamics are perfect and no ill-effects during rain when wipers are working. Fuel consumption did no increase. I live in a country where it rains quite a lot, but did not notice any water in the filter box after driving/parked in a heave rain, so that is a good thing. One downside however, since it is my first car with snorkel fitted to a turbocharged V8, noise from the intake when that 4.5 lt engine revs up is considerable and may disturb some, not me tough :-).
