A BIG MAF for the big boys & girls!

Horsepower is a direct function of airflow. Simply put, if you can’t flow the requisite oxygen, then you’re not going to meet your horsepower goal. With that said, the factory mass air meter, like any other sensing device, was only designed to register so much airlfow. After a certain point it will no longer indicate that the engine is ingesting more air, and the engine will at best fuel cut, or at worst run dangerously lean. The fix for this problem is to install a larger MAF housing, along with a new transfer function for the sensor.

cp-e™ recently released the XcelXL™ along with a new corresponding ECU flash which alters the MAF sensor’s transfer function. This combo allows the sensor to register enough air for over 600hp, as well as reduces a bottleneck at the inlet of the turbo. As you can imagine, the 3.25″ housing is going to have a much lower pressure drop than the factory 2.75″ housing.

The XcelXL™ comes as a generic kit that can either be bolted directly to our Inviscid turbo inlet, or may be used for a custom fabricated intake system. The valve cover recirculation hose has is deleted and replaced with an oiled valve cover breather filter so the housing can literally be coupled anywhere before the turbo. It also comes with a 3.5″ air filter, and 3″ to 3.5″ transition coupler. So whether you’re making your own custom intake, are going for BIG power, or simply want less restriction at the turbo inlet this kit is key.

Edit: Worth noting, its listed at $250 for the kit. But it requires the Full Control Flash from them, which is close to 500 bucks. though if you have it already its 35 bucks for the Big MAF Flash. But also this is part designed for people who have pushed the limits of the stock MAF, which probably means they have the standback or full control flash already.
