In this video, I pull my BMW E46 M3 into the garage after months of working on the E30, and give it some well-deserved love and attention, in the form of a new intake from the guys at Eventuri and Evolve.

I’ve always dreamed of fitting the full BMW E46 M3 CSL carbon air box to my car, for the noise alone, but with their prices soaring, I think the opportunity may have vanished for me to pick one up, so I;'ve been stuck with the stock plenum, air box, and panel filter for years.
Eventuri’s unique E46 M3 intake design has been on my radar for quite some time, but I’ve always been a sceptic of bolt-on aftermarket intakes, they often look a lot better than they perform, and in some cases even cause a loss of power thanks to things like heat soak in the engine bay.
After doing plenty of research into the Eventuri intake for the M3, I came to realise that this one is different. It’s clearly evident that the guys at Eventuri and Evolve take engineering very seriously, and are very proud to show that off by sharing detailed data and even air-flow models from their research and development to back up their stated power gains.
After all, more air and fuel in equals more power, so increasing the intake air velocity and smoothness is certainly compelling in the quest for performance. The Eventuri intake achieves this by invoking the venturi effect (hence the brand name) thanks to the design of the bell-shaped carbon fibre filter housing and aerodynamic reverse cone air filter.
For the BMW E46 M3, Eventuri state increased horsepower of 10-15hp and 8-12ft-lb of torque, which I find to be impressive on the standard ECU map tune of this already highly strung naturally aspirated S54 powered car.
Further to this, they promise upwards of 360hp when the E46 M3 Eventuri intake is paired with their Evolve remap.
As stated in the video, I’m not really trying to tease more performance out of the S54 motor, the stock power is more than enough for the road use the car gets. It never goes on track either.
But the promises of a performance gain does provide plenty of reassurance in the quality and design of the E46 M3 Eventuri intake, and I can feel pretty certain I won’t be hampering the performance of my M3 by fitting one.
However, what really pushed me to pull the trigger on buying an M3 Eventuri intake was the promise of aural pleasure.
Many owners attest to the increased induction roar and intake noise generated by Eventuri’s design, stating that the Eventri intake effectively turns the M3’s S54 engine into a musical instrument played by your right foot, just like the CSL plenum is famed for.
Knowing the full CSL airbox is out of reach, and discovering how accessible the Eventuri intake is compared, in terms of both cost and difficulty, I had to have one.
Once I’d got over the beauty of the intake I’d received, fitting it to the car was a breeze. Evolve Eventuri have done an excellent job with their PDF guide. Installation only requires simple hand tools, so even someone with no mechanical experience would succeed in fitting it. I was off to a good start.
Once fitted I allowed the car to warm through, initially unsure of any change in sound as the car idled. On the open road, with sufficient oil temperature, I was able to apply more than half throttle for the first time and was immediately showered by harmonious induction noise as I sat in the driver's seat grinning from ear to ear.
It seems the Eventuri intake makes most of its tuneful intake noise between 3000 and 6000 rpm with the throttle bodies wide open. In this rev range, a very definite and characterful bark has appeared, adding to the already great driving experience of the E46 M3.
So far, I can wholeheartedly recommend the Eventuri intake for BMW E46 M3. This video is not sponsored and all opinions are my own.
