Its a proven fact that cold air intakes produce horsepower gains. By relocating the main factory air induction source from inside your almost overheating engine bay, to areas outside the engine bay (in some applications; deep in the fenders, wheels wells, etc.), can help provide your engine much cooler air which carries more oxygen. More oxygen equals more intense detonation in your combustion chambers, which ultimately creates more torque and more horsepower. Sonar cold air intake systems provide such improvements without leaning out your air-fuel-ratios, while also saving you huge bucks over other cold air intake systems. Sonar cold air intakes come in a gloss blue finish, gloss red finish, polished chrome finish, and in a new stealth flat black finish.
