Do NA engines have boost?

Naturally Aspirated (NA) engines are not equipped with turbocharging or supercharging devices, so they do not have the "boost" function. Their air intake relies entirely on the negative pressure generated by piston movement to draw in air, with a pressure of approximately 1 atmosphere. Compared to turbocharged engines, NA engines have the advantages of linear and smooth power output, simple structure, and lower maintenance costs. For example, Hyundai's 1.4L G4NA engine can provide stable torque at low speeds, making it suitable for daily commuting. Turbocharged engines, on the other hand, enhance power through forced air intake but have issues such as turbo lag and higher maintenance costs. If you pursue driving smoothness and fuel efficiency, NA engines are an ideal choice; if you focus on power performance, turbocharging technology should be considered.
