How to install Malossi Air Bushings?

I ordered a Red Sponge Malossi Air Filter insert for the OEM air box.  S.I.P recommended to also install the Malossi air bushings into the air box when using this filter.

I received the bushings, but no instructions or diagram on the best way or position to cut the air box to install these bushings. Also, do you install ALL of them or just the number you need to tune your air intake? Thanks for any help on this.




you have to use about 3-4 of the bushings.


only drill  holes, in the right size, in the front cover of your air cleaner housing
