Description

The Ferrea E11147 is a set of 12 titanium valve retainers designed for Toyota GR Supra 3.0L B58 turbo engines and compatible BMW models. Made from aerospace-grade 6AL-4V titanium, these retainers reduce weight by 40% compared to steel, allowing for high RPM operation up to 10,000+ RPM. They feature a 5.0mm stem design for precise fitment and weigh 11 grams each, contributing to lower reciprocating mass and improved engine acceleration.
