Question: what is the difference between 8 valve and 16 valve?
Answer: Well 8 valves (8v) basically means a 4-cyl engine with 2 valves/cyl (one for intake and one for exhaust). 16 valves (16v) means 4 valves/cyl (two each for intake and exhaust). ... 16v engine for the same capacity will be a bit more expensive than its 8v equivalent - but it will have better performance.
