Mazda CP-E Mazdaspeed6 Xcel Cold Air Intake
The factory intake is great at one thing, suppressing horsepower and all the cool sounds that a turbo car makes! There is only one inlet on the Mazdaspeed6 factory airbox even the 6s and6i have two inlets. The 6i and 6s have the exact same inlet plus an additional inlet that opens in the higher RPM ranges. There is a substantial amount of horsepower to be made by replacing the intake.
Turbo cars are very sensitive to temperature increases, therefore in testing cp-e tried both a short ram intake and a cold air intake (CAI). After measuring temperatures throughout the intake track cp-edetermined that a CAI was in order.
The Xcel Mazdaspeed6 intake is the first intake only for any Mazda6 that will not set a check engine light (CEL). cp-espent a great deal of time engineering and figuring out a way to mass produce an intake that would not set a CEL. cp-e determined that a similar design to the 6i and 6s would be used. Improvements were made to the heatshield that doubles as an ABS harness holder.
