You have to take off your windshield wipers, then the wiper cowl, pull off your air intake and there should be I think 2 bolts and a torx bolt and it should pop off. If you have problems getting it off because of the bottom bracket you can slightly loosen the mounts from the transmission. Then disconnect your two sensors on it. Then you should be good to go for cleaning! If it's really dirty you should expect a lower idle and some better off the line acceleration!
