After discussions with many GR Yaris owners about airbox modifications, Forge Motorsport are proud to release the Toyota Yaris GR Inlet Duct. The Forge inlet duct allows you to add an aesthetically pleasing carbon fibre part to your Yaris GR’s engine bay and help keep your inlet temperatures down during spirited driving and whilst on the track or rally stage. 

By utilising 3D scans and SolidWorks CAD, our development team have been able to optimise the size of the inlet duct, creating an increase in uninterrupted cold air to be scooped into the stock airbox. 3D printed test parts were used alongside CAD simulation to ensure the optimum size and geometry. This inlet duct performance car part is much larger than stock with a close fit to the front bumper and airbox to ensure that the heat from the engine causes minimal effect.

During testing on track days, the original duct caused inlet air temperatures to be heavily influenced by heat soak and fluctuated dramatically. Meanwhile the Forge inlet duct kept the inlet air temperatures not only reduced but at a more consistent temperature. A reduced consistent temperature is of great importance because any high temperature peaks will cause the ECU to retard the ignition and reduce the power you have available. The Forge inlet duct design incorporates a free-flowing path to both the upper and lower opening of the airbox, whereas the stock design has no flow management to the lower opening and the upper is small and not fully sealed. It is worth understanding that the lower opening is of far greater importance to the performance of your Yaris GR. There is a vacuum operated flap which is activated when under full throttle conditions, therefore the Forge Motorsport Inlet Duct ensures that your Yaris is getting colder directed air when the engine needs it the most.

Data was collated and logged live by a passenger on a track day running in conjunction with an aftermarket intercooler on a 5 lap open pit session back to back against the stock inlet scoop (another 5 lap session). Inlet air temps had been reduced from 42°C to between 35 and 36°C. We even saw temperatures of up to 45°C on the stock duct. Fluctuation between temperatures on the stock inlet duct were greatly improved when air was fed to the secondary inlet scoop via the composite Forge Motorsport inlet feed.

With the OEM design including open sections, baffles, and noise restrictors to disrupt the airflow,

Love these shirts
Size: Small, Color: Watermelon, Number of Items: 1
Love the fabric. They feel so much better than some of the other shirts I have. They’re thicker and just feel nicer. Love this color too. Got a small and also have another color in medium. Both fit, just depends on how casual I want to look. I’ll be getting more!

Will buy again
Size: Large, Color: Washed Denim, Number of Items: 1
Great shirt! The material is very comfortable on my skin. It is a little tight in the neck but pulling on it ever so slightly fixed it for me, other than that it fits perfectly!

Great price; some fitting notes
Size: Medium, Color: Washed Denim, Number of Items: 2
The shirt looks good, good quality, and the price is pretty much unbeatable. Some notes of fit: compared to the Eddie Bauer men's medium legend wash (my standard), this one has a smaller neck opening and is a bit tighter around the chest. Also, the short sleeves are shorter than Bauer's. These aren't really criticisms, but they may work better or worse depending on the person wearing them.

Comfortable, Colorful, Soft, Affordable.
Size: Large, Color: Ice Blue, Number of Items: 1
These T Shirts are as good as it gets especially at the price point. All cotton, very soft, very colorful. Wash well. If you don’t want them to shrink, I suggest air drying them. I had an XL one for years and pretty much ignored it. Found it again and it’s amazing to wear to bed or around the house. At These prices if you need or want a T shirt, this is the one to get.

The Perfect Tee Shirt
Size: X-Large, Color: White, Number of Items: 2
I bought one of these shirts to see if they’re as good as the customer reviews suggest. They most certainly are! They have a nice weight, a great fitting collar, and the shirts have a generous length so they stay tucked in. The sleeves are longer than normal tee shirts, which I really appreciate. These shirts are such high quality, and such an amazing bargain, that I bought four more!
