You don't want the CSL dipstick! You have to remove the whole 2nd section of the airbox every time you want to manually check oil level. I have it on mine and it's a major PIA. Going to bend my original factory dipstick and reinstall it sometime soon. People have different ways of mounting them or simply bending them to go around the CSL box so it's still readable without pulling pieces off.
