After three years of development, we are proud to bring you our GR Yaris Airbox Intake kit: unique in its design and engineered to current top motorsport specifications, this airbox enables you to use the stock panel filter in order to maintain OEM Service of the car. It is possible to install aftermarket panel filters to obtain even more performance. When combined with an aftermarket panel filter, we found over +16bhp over the stock unit on OEM ECU settings, and further improved performance across the power band on Stage 1&2 EcuTek engine software. The power gains increase with the total engine power output, so results will vary depending on your supporting mods and engine tune.
These results were possible thanks to careful flow analysis, that also led us to re-use the OEM Turbo air intake pipe up to the airbox itself, as larger diameter pipes only lead to loss of air density in all applications under 550bhp, hence more turbo lag and less torque.
Laminar Airflow & SF Air filter
PIRAS Motorsport Airbox Intake kit allows for faster spool and fresh air collection, with the most laminar flow of any other solution on the marked, directly feeding air from the front bumper to the stock format (OEM) panel filter, that is crossed at exactly 90 degrees.
We offer option of purchasing our AirBox with and without a high flow air filter element, and in all cases the car remains fully serviceable by Toyota.
The Sprint Filters "P08" material air filter is the most technological advanced air filter available on the market today: instead of using sponge or multiple layers of oil-bathed cotton, this next generation filter uses a technologically advanced Polyester material with filtration of 80 micron particles and guaranteed air flow of 5,050 l/m²/sec (about double the flow of the leading cotton filters): these are characteristics unattainable by filters that use other materials. These values make the P08 a very versatile and efficient air filter, suitable for road & track use.
Filter cleaning is very easy, only requiring compressed air and no lubrification, and it is designed to outlast the car itself.
Please beware that, given this direct, un-interrupted air flow, it will be necessary to check, clean or replace (if using the OEM paper unit) the air filter more frequently than with the OEM airbox.
MAF Sensor Housing
Unique to PIRAS Motorsport Airbox Intake AirBox kit is also the “HP MJF” 3D Printed MAF Sensor Housing: thanks to its perfect dimensional accuracy, it enables the cleanest sensor readings possible, for consistent tuning and repeatable operation with no issues.
MADE IN ITALY
The Airbox is Made in Italy in stamped plastic and features a sheet metal inferior bracket that mates perfectly with the OEM mounting points. No modifications are necessary for installation, that can be performed in less than 30 minutes with simple hand tools.
No corners are cut when engineering, developing and producing our products!!
TUV Homologation
While this Airbox is intended as a Motorsport product, TUV homologation is on the way, under form of ABE approval number for KBA.
