Trying to break the 400HP mark? You’re going to need a larger than stock MAF housing.  The MAF sensor in the factory housing simply doesn’t have the ability to register 400HPworth of air. Moreover, big turbo performance will be stifled by a standard size MAF housing. cp-e™ has created the XcelXL™ to help alleviate this restriction.

Limited Edition Black Anodized MZR 2.3 DISI XcelXL™ Air Intake

MMZRXX

 

Price: $269.00

With the cp-e™ XcelXL™ the possibilities are endless. It is offered as a simple MAF housing that can either be used as a short ram intake, that is a direct fit with our Nviscid™ inlet pipe, or it can be integrated by the end-user into a custom intake system for whatever setup you need.

The XcelXL™ comes as a kit with a 3.25in MAF housing designed to fit the stock MAF sensor, a cp-e™ 3.5in filter with a built in velocity stack for optimal airflow, and a breather filter for the crank case ventilation, as well as all the necessary hardware for a direct fit to the cp-e™ Nviscid™ inlet pipe.

In order for your ECU to recognize this increase in air flow through the stock MAF sensor, you will have to custom tune your vehicle.
