Hope this is not a dumb question.What is the purpose of the black plastic that goes over the air filterinside the air box?Is it really needed? Has anyone run without it?Thanks for your time.Ryan
When the lock on your airbox 'splodes, it keeps the metal bits from getting sucked into your engine....
It is there as a low $ retrofit for leaky airboxes that allowed unfiltered air to enter the engine through gaps and such on the airbox. The otherway people were repairing this flaw was with a wrap of tape around the seam and hinge area of the box.
In these posts I've noticed that there are those who don't recommend K&R filters. Someone please assist this gentleman. Me too, I wanna know.
