Haha - made you look! Anyone tried running without the rubber bungs in? Surely would breathe more freely?
If they are the bungs in the air runners, they were fitted to lower the intake noise for homologation. The dealer removed mine from my 996 before delivery, I'm surprised any bikes still have them fitted. I would remove them.
They look like duckbills, they are to allow water to drain out, but act as a non return valve to prevent ingress. I would leave them in place.
Just looked at the parts catalog and they’re called restrictors - fitted from 99 onwards. Will remove....
they only added them for the 996 model onwards to restrict the noise in the airbox apparently, bin the fookers
Hi - no I’m not referencing them. It’s the 2 big rubber bungs that go at the airbox end of the intake. As per other reply they’re called Restrictors and only fitted 99 onwards
Are these pre or post filter, if post filter they will draw in unfiltered air. Not a lot of volume but unfiltered all the same. Not good on dusty roads.
If the holes are between the filter and the throttle body. You are correct the air will be filtered, but any air drawn in through the holes left when the bungs are removed, will be unfiltered air and will mix with the filtered air. The result would be the same as punching holes in the air filter.
The bungs fit inside the air tubes and have no affect on filtration. They will be pretty rare now, keep them as a souvenir
Some suggest taking them out, some suggest leaving them in, on balance I think you should take one out and leave the other one in ! PS the only worry re above is this could lead to a massive horsepower increase in one cylinder only , should add at least 80bhp I would have thought, this could result in unequal forces being applied to the crank resulting in it snapping .
Which rather worryingly includes taking flight safety decisions for large gas turbine engines in civil aerospace, enjoy your next flight!
