Nope, there is absolutely no increased risk of a cigarette or other large particle getting into the engine if you remove the snork, cause as you see below, there's a mesh screen in the intake right before the MAF.

I don't smoke either - but my radiator cavities seem to fill with butts quickly.

Getting a butt into the engine wasn't what I was worried about. If someone flicks a still-lit butt and it ends up ontop of a paper filter having massive amounts of oxygen pulled through it, it will catch the filter on fire.

I know the stock filter has foam on top of the paper, not sure if that would help or not.

Thing is, the snorkel tube itself was not put in for the purpose of blocking out cig butts...the protruding lip on the painted air vent housing was put there to redirect objects over and behind the intake, so taking the snork tube out will not increase the risk of a cig butt going into the air filter housing. In fact, I have seen cig butts in the foam portion of the air filter even in cars WITH the snork still in place. If a cig butt is going to get in there, it will get in there regardless if the snork is in or not.

I've had my snork out for years without issues. I even took a dremel to the section left after pulling the snork out to smooth out and widen the hole since I didn't like the hard edges left in the opening after pulling the snork out. The sound is terrific, and my filter hasn't caught fire.

I don't have any dyno evidence but something that was interesting to me none the less. I have a 2004 special edition which had slightly more power than the standard 2004 Boxster S from the factory. My understanding is the extra horsepower was basically achieved by an intake change and an ECU re-flash from the factory.

I compared my intake to one from a friends older Boxster S and indeed mine was pretty drastically different. However, one other thing that was interesting was my snorkle was massively larger than his was. I've not been able to compare a "standard" 2004 Boxster S to mine yet, but if it's the same situation it might lead one to believe a de-snorkle could have some slight added hp benefit.

Anyone got a picture of a snorkle off a standard 2004 Boxster S? I'll take a picture of mine and post it.

Here is a picture if the inner dimensions of both ends of my snorkel. It was taken from a 2004. I have done my best to be as accurate as I can.

Doing the math indicates that the cross section area of the small end is about 44% smaller than the larger end (which goes directly into the air box). When you remove the snorkel, the air entry into the air box is now slightly larger than the large end of the snorkel. I still find it hard to believe that this does not cause some obstruction of airflow.

I am hoping to do some mods to my car this summer. I was thinking about doing a dyno it after each mod. If I can, I will try to get with and without snorkel dyno results.

quite interesting.. a year ago i've put up this question if it was possible to do this on an 04S and i don't think anyone had done so, or just did not post a reply.
reason was, i attempted to do it on my 04S and no amount of wiggling the plastic grill after taking off the one screw, did not budge and i was afraid to break the part..
i hope you could shed light on this?
thanks for sharing.

I did my 2004 S. I remember it being a bit scary to get it to come loose though.

backman_z · 06-05-2010, 07:01 PM

I was also very concerned about breaking the vent to get to the snorkel. I had to pull and wiggle over and over again, but eventulally, it came out.

The area inside was so small, that I could not get a good grip on the snorkel. So, I clamped some vice grips on, and it came right out.
