#2i had a piper x foam filter on the car when i got it and its by far the loudest roar imo but does naff all for performance as it just soaks up all the heat from the engine! (mite take while for new filter to bed in and become louder)

#3if its a second hand one then may need a clean. As above they dont help performance really
-
#4didnt want it for proformance just wanted it for the sound at the front
-
#5I had a piper x it did nothing seen a small gain with green cotton

#6green is better i wud say
