Cold air induction is a more efficient air intake method. Cold air induction can unleash the latent potential in power and fuel efficiency.
The cold air induction process: Air first comes into the Air Dam, which keeps out hot air from the engine compartment. The result is that the air entering the filter is cooler and dense, providing for a more potent air charge.
The ROUSH air filter media is a synthetic nano-fiber material that traps the smallest dirt particles that ordinary cotton-gauze "performance" filters can’t capture. Based on SAE standards, ROUSH air filters capture almost twice the percentage of 2 micron particulates, and more than six times the amount of 0.5 micron particulates than our competitors’ filters.
