Subaru WRX Intake Valve – GSC Power Division 21-4N Chrome Polished (2015-2027). A precision 34 mm standard-head intake valve for FA20F WRX applications, sold individually.

Constructed from 21-4N stainless steel, this valve is designed to handle the elevated heat and stress of turbocharged use. The chrome-polished finish encourages smooth airflow and helps limit carbon buildup for consistent sealing over time. With a factory-size 34 mm head, it supports proper fitment and seating when paired with stock-sized components, making it a smart choice for engine refreshes, maintenance, or performance-focused builds that retain OE dimensions.
