Perrin Blow Thru Boost Tube Intercooler Piping

The Blow-Thru Boost Tube is a replacement of the large 2.75" tube in the Perrin FMIC kit that relocates the MAF sensor into the boost tube. The way the MAF sensor works is very simple, and it doesn t care, or know, if it is under boost or vacuum. This means the sensor can placed in the boost system, or in the intake system, and function normally.

With the MAF sensor located in the boost tube a short distance before the throttle body, any possible leak in the intake system will never be a problem. And being so close to the throttle body, most possible leaks in the boost system are not going to be a problem either. Also if you have ever had a boost tube blow off and leave you stranded, that is a thing of the past!

One feature many people like is that a Vent to Atmosphere BOV can be used with out the issues associated with a normal intake. The BOV is normally located after the MAF sensor in the boost system, and vents the air back to the boost system after the MAF sensor. With a normal intake, it is important to keep the vented air (from the BOV) in the intake system after the MAF sensor, so the ECU can calculate the amount of air the engine is consuming. If you install a BOV that vents the air to the atmosphere, it is like a boost leak, and can cause the car to run rich. This happens because the air the ECU thought the engine was consuming didn't get consumed and extra fuel is added. This causes back fires, and during low RPM situations can cause stalling.
