Hiflofiltro Oil Filter — HF303RC

The race-spec version of the premium oil filter, built for engines that see redline laps and want a 17mm hex on top so you can torque it without crushing the can.

• Same filtration media and bypass-valve spec as the standard premium filter, in a heavier-gauge steel can.
• 17mm welded hex nut on the end cap so you can torque it accurately and remove it with a wrench instead of a strap.
• Safety-wire holes drilled through the hex for tracks that require lock-wired filters on race-prepped bikes.
• Anti-drainback valve holds oil in the filter at shut-down so the gallery primes immediately on the next start.
• Recommended where the rulebook calls for wired filters or where you change oil between trackday sessions.
