Supertech Subaru BRZ/FRS Exhaust valve 30 (+1) x 5.45 x 97.7mm INCONEL

This listing is for a single Supertech exhaust valve for your Subaru BRZ or Scion FRS. It measures 30mm in head diameter, which is 1mm larger than the stock size, and has a 5.45mm stem diameter with an overall length of 97.7mm. This valve is constructed from INCONEL, a high-nickel alloy known for its exceptional strength and resistance to extreme heat and corrosion, making it a solid choice for performance applications where exhaust temperatures can get very high.

Using an oversized valve like this can help improve exhaust flow from the cylinder, potentially leading to better engine performance. The INCONEL material is particularly beneficial in high-performance or modified engines where the stock valves might struggle under increased stress and heat. This is a single valve; you'll need to order the correct quantity for your engine rebuild.
