HPS Performance Titanium Coolant Bleed Screw HW22-1001 replaces and upgrades BMW Z4 G29 M40i Roadster (B58D) factory bleeder plastic bleeder screw that are prone to failure. Don’t get left stranded due to a failed coolant bleeder screw. For BMW vehicles, the plastic coolant bleeder screw is a common failure point. To combat this, HPS has produced its own Titanium Coolant Bleeder Screw. This relatively inexpensive upgrade can save you a lot of trouble whether you commute or track your BMW. We chose the best materials for this upgrade. Each piece is precision CNC machined from Grade 5 titanium which will never fail. Coupled with a Viton O-ring which is more chemical resistant than any standard rubber O-ring. For ease of service, HPS has eliminated the awkwardly large crosshead in favor of a 4mm allen head. The HPS Titanium Bleeder Screw looks and works great on most BMW and Mini Cooper vehicles.
