Powerflex PFF5-4631 Poly Bush for BMW 3 Series F30 F31 F34 – Front Selector Linkage Oval Insert

Transform your BMW’s gearchange feel with this uprated front selector linkage insert. The Powerflex PFF5-4631 polyurethane bush replaces the soft factory rubber, cutting unwanted movement in the gear lever mechanism for a tighter, more accurate shift. Expect a more connected, positive engagement that suits fast road driving and daily use alike.

Why it belongs on your 3 Series

• Crisper gear engagement and reduced play in the selector rod assembly
• Hard-wearing polyurethane resists oil, heat and road grime far better than OE rubber
• Direct replacement for OE reference 25117507695 with no permanent modifications
• Designed for F30, F31, F34 platforms using the oval front linkage mount
• Ideal reliability upgrade for manual gearbox shifter feel and consistency
