BCM (Boyle Custom Moto) Air cleaners are machined from 6061 aluminum, then hand massaged to meet their high standards and insure a quality fit and finish.
BCM enlisted the help of some trusted motor gurus to help in the basket design. This basket design greatly minimizes air restriction and with the addition of the "vortex cone" you get increased and properly directed air flow. The high percentage open area stainless cage allows more air flow to pass through quickly and easily.
With a lot of help from the guys at Uni Filter the right foam density for a BCM propriety big twin filter element was created. Uni filter cuts and glues the filter specifically for BCM to ensure the best fit.
To take the guess work out installation all of the mounting hardware is one size stainless flat head socket bolts however an extra slotted oval head bolt is included for the lid just in case that's the look your going for. We do strongly suggest applying a dot of blue thread lock on all threads during installation. Dimensions 1-1/"� x 4"�.
