Eventuri Carbon Fiber Intake for the 3-Cylinder GR Corolla Makes a Monster Statement

  • The new 2023 and 2024 Toyota GR Corolla comes with a 1.6-liter turbocharged three-cylinder engine that makes 300hp and 273 lb-ft of torque.
  • For the Pit+Paddock GR Corolla project car, Eventuri supplied its gloss carbon fiber intake system which has shown dyno-proven gains of 15-17hp and 15-18 lb-ft of torque.
  • Priced at $1,645, the Eventuri GR Corolla intake system is the most expensive on the market.
  • After installing the intake at Evasive Motorsports, the look of the engine bay has improved drastically, while the acceleration gained is noticeably quicker.


By now you should be well aware that the GR Corolla is an underdog in its segment. Turbocharged competitors like the Honda Civic Type R, Volkswagen Golf R and Hyundai Veloster N are all powered by a 2.0-liter four-cylinder while the GR Corolla comes with a 1.6-liter three-cylinder. Despite being short one cylinder and 400ccs, the G16E-GTS can hang with its four-cylinder rivals and produces 300hp and 273 lb-ft of torque.

The Toyota engine is currently the most powerful production three-cylinder in the world – lighter and more efficient than any four-cylinder out there. Its backstory is also worthy of praise as the straight-three was designed for the GR Yaris WRC rally car. Regulations required a max displacement of 1620cc, which spawned what would become the engine that’s equipped in both the road-going GR Yaris and GR Corolla today.

Although the small engine packs a mean punch with a 0-60mph time of 4.9 seconds, there’s still untapped potential, which companies like Eventuri know very well as its GR Yaris carbon fiber intake system has been one of its best sellers for the last three years.


It’s no mystery why our Project E92 M3, the Dream Car Raffle G80 M3 Competition, and the E91 GTS Tribute all use Eventuri intakes. It’s because they are the best. Period. Here are a few reasons why:

Born from Physics. Eventuri is a far cry from an average shop making intakes out of colorful cone filters and aluminum piping. The UK firm was formed in 2014 when co-founder Bilal Mahmood used his background in aeronautical engineering and thermodynamics to design a new generation of intakes. By applying the principle of the venturi effect, airflow is accelerated through each Eventuri intake system, which ultimately produces more power than any conventional airbox or old-fashioned cold air intake kit could achieve. After 3D-printing a proven prototype, and then teaming up with co-founder Imran Arshad of Evolve Automotive Tuning to bring the first applications to market, Eventuri has truly revolutionized the way we look at aftermarket intakes and how they should perform.

Backed by Data. A concept is only as good as the data that backs it up, which Eventuri demonstrates with each intake kit it releases. Taking into account volumetric airflow, intake temperatures, aerodynamics, and dyno testing, there are hours of testing and data logging done to ensure that all the inefficiencies from the stock airbox are eliminated. The result is a proven product that generates the highest airflow, achieves maximum pressure, provides the coolest air temps, and of course, nets the most power.

Quality You Can See. In addition to the performance gained, the componentry of every Eventuri intake kit is top-notch. The housing, ducts, and hoses are constructed of 100% carbon fiber, the filter is custom-made, and the parts are assembled by hand in the UK. You can tell its premium quality the moment you open the box or see it under the hood.


With a compact three-cylinder under the hood of the GR Corolla, there was much more room for Eventuri to take advantage of. Hence, the largest intake filter in the Eventuri range was used measuring 8.3” with a 4” opening. The filter also tapers down to the tubing for this application which aids the venturi effect further.

Dyno testing by Eventuri’s partners has shown gains of 15-17whp and 15-18 of torque. As consumers, normally we’re skeptical of manufacturer numbers, but Eventuri’s numbers don’t lie. You can search online for independent dyno tests, but as someone who’s tested a wide range of intakes before on various project cars, what Eventuri has introduced for the GR Corolla is no joke.

The moment I got back on the road after the install, I could immediately feel the increase in horsepower and torque as the boost kicked in. The induction sound also intensified which added more excitement to the GR Corolla’s driving experience. Lastly, popping the hood is something I don’t normally do on stock motor cars, but the massive size of the intake housing and the fit ‘n finish of the carbon fiber makes a big, bold statement that fellow enthusiasts can appreciate.

The toughest part about going Eventuri is the price. They are undoubtedly the most expensive on the market, and the GR Corolla intake lists at $1,645. I can’t speak for everyone, but if I already invested in a $40K GRC, I’m not going to buy cheap parts, especially on a fundamental bolt-on upgrade. When it comes to Eventuri, you’re not just paying for the brand name, but for the latest technology, dyno-proven results and quality you can see, hear and feel.   

Thank you to Evasive Motorsports in Cerritos, California for assisting with the installation of the Eventuri GR Corolla intake (EVE-GR4CR-CF-INT). Detailed installation instructions for the Eventuri GR Corolla intake can be found on Eventuri’s website.

Disclaimer: Many GR Corolla owners are experiencing a check engine light when installing an aftermarket intake. After a few days, a CEL eventually came on. I’ve learned to live with it; however, Eventuri is working on a to fix the issue, and I hope to have an update for you soon.
