One set of 8 oversize exhaust valves. These are one piece forged 21/4N stainless steel valves. The valve head shape has been flow bench developed to maximise air flow. These valves are ideal for a tuned naturally aspirated 2.0L or 2.2l engine; the cost is less than a standard OEM valve and changing to the larger valves gives a significant gain in air flow; even without any gas flow work; although the valve seat will require re-cutting to suit the larger valve.
