No, get rid of it, is this a K&N style filter? If so, its more for show than go.Get a proper 1/8 buggy airfilter or universal one like from OS, or Ofna, Losi etc.

Is this on your MT, the bigges issue, ensure the area around the carb boot is clean, remove it, take your finger or a clean white cloth and check the inside of the airfilter boot for debris. If youfn some, chances are they were also ingested by your motor.
