Eventuri Is The Rolls-Royce Of Performance Intakes, But Do You Need One?

We install one of the industry's priciest carbon fiber intake systems for the 2020 Toyota Supra and determine whether it's worth the pretty penny or not.

When I was in the process of building my 2020 Toyota Supra for SEMA last year, there were virtually no aftermarket intake systems available. It also wasn't easy as going to Home Depot and slapping one together like the old days (I've had my fair share of homemade intakes and they did the job). These days, you have to worry about efficiency, heat and air flow more than ever, not to mention you gotta worry about things like sensors and other variables.

So SEMA 2019 came around and while the outside looked the part, I kept my hood shut. I was bummed to hear that the folks over at Eventuri had personally delivered a select few carbon fiber intake systems for a handful of A90 Supras at the show, one of which was Daniel Song's Pandem widebody, which they installed inside the Toyo Treadpass (wild!).

I'd always heard of Eventuri as their systems have been a favorite among the most elite and highest-performing European sports cars out there. Case in point, we featured CSF Radiator's 986whp Porsche 911 recently with their intake installed. They've continued to expand their product line with cars like the Civic Type R (recently equipped in HondaPro Jason's 454whp FK8), and now the B58 Supra. Now it was my turn and it was finally time to see what Eventuri was about after all these years!

THE SOMETIMES TOLD BUT NOT WELL-KNOWN STORY BEHIND EVENTURI

Based an hour outside of London, Eventuri is still a relatively young brand having started in 2014 (three years after I'd left eurotuner magazine). Two very smart, well-educated gentlemen sit atop the Eventuri throne, Imran Arshad and Bilal Mahmood, who I was lucky enough to catch up with. Bilal isn't your typical car guy that performed odd end jobs here and there and wrenched his way up the ladder. He was a car guy at heart and graduated in 2001 with a master's degree in Aeronautical Engineering.

Destined to easily earn a handsome lump of money designing some sort of groundbreaking aircraft technology, Bilal followed his passion. After understanding the deeper science behind airflow and thermodynamics, he decided to take what he'd learn and apply it to car intake systems, an area where he always felt had compromises from the factory, and with other aftermarket kits out there.

In 2013, 3D printing became affordable and he bought a printer, eventually designing the trademark Venturi housing concept right in his own kitchen! It was then that Bilal connected with Imran who was running a shop called Evolve Automotive at the time. Evolve's demo car was a E60 BMW M5, and Bilal and Imran worked together to come up with a prototype intake for the S85 V10. After multiple tweaks and dyno runs, the numbers didn't lie and Eventuri was born. Following the E60 M5, Eventuri broadened its BMW lineup with M cars; however, Bilal tells us the kits for the F80 M3/M4 and Audi B8 RS5 are what really put them on the international map.

ABOVE & BEYOND DESIGN WITH REVERSE-MOUNT FILTER

Intakes are more or less the same, right? There's an inlet pipe, cone filter, heat shield, brings in cooler air, etc. Yes, that's true, but not every company goes about it in the same way. In the case of Eventuri, let me remind you that Bilal can flex a 'lil bit more knowledge than most when it comes to air and heat efficiencies. He explains that the design and materials used of every Eventuri part has "no compromise", meaning every bit of R&D put into each intake has to have the most laminar flow possible (had to look up "laminar flow" myself. Basically means the airflow has to have the smoothest, straightest path possible with no kinks or irregularities), as well as have thermodynamic principles to keep air intake temperatures as low as possible.

You'd think all intake brands follow the same game plan, but the truth of the matter is many companies make sacrifices and cut a corner or two to keep costs down. This ultimately results in systems that might not perform the same as OEM, and possibly worse. In addition, you won't find any other intake out there with Eventuri's reverse-mount filter system. The cone filter is inverted which, in essence, allows the carbon housing to dictate the flow of the air, not the air filter. This unique funnel-shaped design helps smoothly guide air into the inlet tube and creates a Venturi effect, ultimately increasing air velocity. More air at a higher flow equals a win-win.

INSIGHT ON THE TOYOTA SUPRA A90 INTAKE

When I first picked up my Supra, I was always curious if Eventuri was going to make an intake for it. They don't cater to too many Japanese cars, being a UK-based company, but their first offering was an FK2 Honda Civic Type R (we didn't get this car in the States), followed by the ever-so-popular FK8 Civic Type R. Admittingly, the Supra is only their third Japanese car offering (and it's quite frankly a BMW), but for guys like me who embraced the Supra's Bavarian bloodline, I rejoiced at the opportunity to test it out and see for myself what Eventuri was all about.

The moment my kit arrived I knew it was something special. It's hard to describe how immaculate the carbon inlet tube and airbox are. It doesn't just look perfect but feels perfect, from its overall shape, the direction of the carbon weave, the buttery clear coat finish, the choice of hardware used, etc. This system screams high quality, even before I had it installed and started up the car.

As for installing the intake, it's a pretty straightforward job and took less than an hour in a home garage. Eventuri provides detailed instructions which illustrate every step and doesn't leave any guesswork. What you don't get from their instructions is all the insight that went into the Supra's intake design. Bilal tells us the biggest challenge about the A90 was that the airbox sits right next to the exhaust manifold, one of the hottest places in the 3.0-liter inline-six's engine bay. From his experience, turbocharged engines are sensitive to IAT values (air temps), so he knew from the start it had to be a fully sealed system (thus the carbon box). He also mentioned there's a misconception out there that cars with an intercooler or charge-cooler can bring intake air temps down to alleviate hot engine bays. Hot air is hot air and it'll always be less dense which will result in the turbo not reaching target boost.

To demonstrate their due diligence, Eventuri tested an open cone filter on the Supra to see its effect on power. Because the filter wasn't sealed and was more susceptible to heat, the turbo took longer to reach peak boost and they discovered a loss in acceleration after 60mph. The next easy step would be to move the air filter further away from the manifold or create a ducting system to draw in cooler air. For the Supra, this was impossible as the intake sits right behind the passenger-side headlight area in the bumper. The fake vents in the bumpers also couldn't be modified to work (bummer). Bilal and his team managed to find a secondary air feed between the chassis and wheel liner, which is why the box features a scoop style extension. The intake tube is also enlarged to a diameter of 4.4" which strategically tapers down to the turbo for optimized flow (Note: Eventuri eventually released a carbon headlight duct, but of course, I drive my Supra on the street, and value seeing at night).

THE VERDICT

The Eventuri carbon fiber intake for the Supra passed every test with flying colors (minus price, where it'll run you $1,395 from retailers like IND Distribution). Its build quality is A+, design A+, and the sucking sound it makes brings a smile to my face every time I hear it and feel the turbo spooling. Whether it makes more power than I remember, it's slightly noticeable but honestly speaking, the motor was already making 400+hp with a tune, AMS downpipe and Akrapovic exhaust to begin with. Any power gains that aren't larger than 30-40hp aren't going to throw you back into your seat more.

The overall engine package does feel tighter, tuned and complete. I have piece of mind knowing that there's the most well-designed and efficient intake system under the hood and I don't hesitate to show it off one bit.

Since the early days of tuning, an aftermarket intake was never going to blow your socks off but help your engine unlock more horsepower from that restrictive, often poorly designed OEM airbox. Eventuri expands on this methodology with today's more complex and high-performance luxury and sports cars. For a modified Supra like mine, they've achieved a gain of 17-20hp from their own dyno testing with up to a 25hp increase in the mid-range and their air flow bench tests have shown an increase of 60 CFM (cubic feet per minute). You inhale and exhale around 1/4 of a CFM of air per breath, so you can imagine that 60 CFM isn't tiny. I haven't dyno'd my own car yet (that's next on the to-do list), but if there's one thing I can attest to, it's that the story and science behind Eventuri is the real deal, and that I've never been more satisfied with an intake system before.
