Supertech Honda B16A 29 x 5.45 x 102.5mm Blk Nitrided Flat 1mm OS Exhaust Valve- Single (D/S Only)

This Supertech exhaust valve is built with a black nitrided finish, a surface treatment that helps resist wear and improve durability in the harsh environment of the combustion chamber. It measures 29mm in diameter, has a 5.45mm stem, and a total length of 102.5mm. This particular valve is 1mm oversize, meaning it's designed to replace a worn or damaged stock valve with a slightly larger diameter for a better seal. It's specifically made for Honda B16A engines and is sold individually for the exhaust side only.

The flat face design is a common choice for many performance applications, offering a good balance of sealing ability and flow. When rebuilding or repairing the top end of your B16A, using valves like these ensures you're putting in a component that's built to handle the demands of the engine. Proper valve seating is crucial for compression and overall engine health, and this valve is designed to help you achieve that.
