First orders will be shipped in CW37, following in CW41.
This product is part of a private collection, available only to those that have already purchased our GR Yaris AirBox and have been enjoying its performance increases. Given we work to continuosly improve our products, we are now offering You this new upgrade at a special price.
All AirBox's ordered after 15/07/2025 will already be delivered as V.2 units.
The V.2 Upgrade for our GR Yaris AirBox Intake consists in a new rear duct and MAF holder, delivered as a single part.
Designed by taking into account the strenghts and weaknesses of our production team, this new unit also features substantial design upgrades and closely imitates the OEM MAF holder.
The smoother radiuses and revised design of the completely new rear Duct & MAF holder increase laminar flow, while the new bonding system removes all glue from the airstream and eliminates the potential for errors within production phase.
As tested by our friends at ACME Motorsport and ProfiTuning, the new unit has a perfect 1:1 reading from MAF sensor, when compared to the original AirBox unit.
This translates into better performance and less adaptation work for your ECU.
The product images capture our prototype version: the final product will differ slightly, in positive.
Testing:
- On a stock ECU with OEM software: Gen.1 GR Yaris on ACME's hub dyno returned a 5.9hp gain over the stock airbox, before having time for adaptations!
- On a stock ECU with Stage 1 software and OEM AirBox, at ProfiTuning, once we swapped to the V.2 AirBox we had to reduce our Wastegate Duty Cycle by 8% in order to remain at the same power level: how is that for increase in flow?!?
- On a Syvecs ECU with Stage 1 software, Gen.1 Rally R1T GR Yaris on ACME's hub dyno, working in Speed/Density mode, only by swapping the OEM Airbox to the V.2 unit obtained 7.5hp of power increase, while eliminating the torque dip and showing more power from 5300rpm to 7200rpm. Of course, software adaptation would further increase these numbers.

From Our Founder.
In 2025 we are here to follow on the next step, with Driving Experiences in Gran Canaria.
At the end of 2013 I sold my tuning company and moved to Turin, where I worked for 11 years as Director in the field of Automotive Engineering Consultancy. During this period, I actively forged relationships and coordinated projects of great success with Ferrari, Lamborghini, Audi, Stellantis Group, Podium Engineering, Dallara and many more customers.

Our Experience.
After taking a BA in Economics and working at Alfa Romeo in global sales, then in consulting, I decided to risk everything and set out to find my path as a rally car driver. With many fewer sponsors than needed, I still managed to race in various Italian and European races, up to the Rally of Sanremo 2007, where I won all GT categories with a Porsche Cayman Rally GT car, on first attempt.
