Hi All!

I recently purchased a 2002 GU body 4.5 liter petrol Patrol. I had though about accessorizing the car and among other things that had caught my fancy was adding a snorkel. I looked through several brands and was almost ready to have it installed when I realized that this would entail cutting a hole on the side of the bonnet. This would basically make it a more or less permanent accessory that I couldn't just take off like a sound system if I didn't like it. Anyway, I wanted to get your thoughts on the matter whether to go through with it or not. I don't really take the thing out offroading. It's really a city vehicle more than anything else. The snorkel just really make it look more of a badass vehicle than it already is. I guess my main concerns are the fuel consumption and effects to the engine with this modification. Will there be adverse effects? Worse fuel consumption? Shorter engine life or earlier replacement of other engine bits?
