Brian Crower Toyota 4AGE 16v exhaust valves, 27mm with +1mm oversize, are supplied as a set of eight for exhaust valve replacement in 4AGE heads requiring this diameter. The +1mm variant indicates the valves are oversized for reconditioning or specific build requirements, and the eight‑valve set is intended to replace all exhaust valves in a 4‑cylinder 16‑valve configuration.
