An air guide filter for an internal combustion engine includes an air filter having a pair of support rings coupled to upper and lower portions of the filter. A pleated filter plate is disposed between the support rings, and an air guide is disposed between the support rings parallel with the filter plate. The air guide comprises a plurality holes defined by half-cone cross-section depressions uniformly disposed about its face, such that, when the air guide is placed at a certain elevation angle with respect to the support rings, air flowing into the filter is guided, rotated and mixed with fuel to generate a uniform air-fuel mixture. The uniform mixture improves combustion and engine performance.
