For those using speed-density systems, the Blow-Thru MAF Tube from Perrin moves the mass airflow sensor from the intake to the intercooler piping for improved readings and accuracy, as well as improved performance.

The MAF sensor is very sensitive, and things like fans turning on, and blow off valves venting can change the readings of the sensor. This causes the car to run erratically in idle and cruise situations. With the Blow-Thru boost tube, the sensor is located in a nice smooth straight path of the charge air, which makes for consistent airflow. This also allows for the proper use of a vent-to-atmosphere blow-off valve.

The Perrin Blow-Thru MAF Tube is available in polished, Signature Series Red, or Stealth Series Black finish and is only compatible with Perrin front mount intercoolers.
