Toyota GR Yaris Power Upgrades


We can’t think of a more anticipated car and when our two Toyota GR Yaris development cars arrived at the end of 2020 we were thrilled that the hype was real. The goal was to make the GR Yaris more useable and fun to drive. We now have a range of products that will enhance your enjoyment of this outstanding performance car.

We will have more information on the development of these and many more new GR Yaris products on our blog and Social Media channels, but below are our initial performance upgrades.


Litchfield Tuning box - 300 bhp



Our custom tuning box allows power and torque to be increased from Toyota’s claimed 257bhp/265lbft to over 300bhp and 290lbft on Shell Vpower.

Our Tuning box features our own custom calibration that the power delivery smooth and predictable with the additional boost at the top of the rev range making it pull much more urgently to the red line. The box is also Bluetooth enabled so you can connect to the box with a smart phone and switch instantly between standard and 300bhp modes.

The box is a simple plug & play design which allows for quick installation (and removal) in around 10 minutes.

ITG Performance Air Filter



The ITG performance air filter is a direct replacement for the original paper air filter. The high quality foam design can be found on motorsport filters from WRC to F1 and allows the engine to breath more easily.





Compared to a brand new paper filter the ITG design allows for an additional flow at the top of the rev range with a 2-3bhp improvement but the main gain was in the area at the bottom of the rev range where the turbos is able to spool up faster. This gave a useful 10lbft improvement between 2,000rpm – 3,000rpm.

Simple to fit this washable foam filter makes future service maintence straight forward and more cost effective.
