Eventuri BMW E90 E92 M3 Carbon Air Intake system
Performance Gain Dyno: 8-10hp, 10-12ft-lb
Performance Gain Road Dyno (Insoric): 16hp, 14Nm
IAT Difference with Ambient: Stock 7.5C : Eventuri 4.5C
V-Box Acceleration : 100-200kph Reduced By 0.3 Seconds
The BMW E9X M3 Eventuri intake system is the result of extensive research and optimisation which improves possibly one of the best designed stock intake systems we have seen. The E9X stock airbox system is a brilliantly designed intake with an excellent flow path and feed system for ambient air. However on closer inspection, there are restrictions in the inlet tube connecting the airbox to the inlet manifold. By redesigning the tube yet maintaining the airbox, we have been able to allow the V8 engine to breathe with greater efficiency and therefore gain power. In addition to the new tube design, we also identified a further restriction in the air feed system. To overcome this we designed a scoop to allow an increase in airflow through the airbox. This reduces inlet temperature values further and adds to the performance gain of the system.
Performance Gain Dyno: 8-10hp, 10-12ft-lb
Dyno tests were carried out showing a consistent gain of approximately 9hp and 11ft-lb of torque. The gain is not just at the peak but throughout the RPM range. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. The car was tested firstly with the stock intake - hood closed. We then left the car on the dyno and installed the Eventuri. The car was then run again - hood closed. Several runs were carried out with both configurations to get a consistent result.
Performance Gain Road Dyno (Insoric): 16hp, 14Nm
The system was also tested using a road based measurement device (Insoric). On the road, the airflow is a lot better than the fan can achieve on the dyno and so the intake system is able to perform better. The following graph shows the difference the Eventuri intake makes on the road compared with the stock airbox. The measured gains were 16Hp and 14Nm : Solid lines show with the Eventuri and dashed lines are with stock airbox. Red line is power at the crank and blue line is at the wheels.
Data Logging Flow and Inlet Temperature
To monitor and record data output from the ECU we used a Bavarian Technic diagnostics tool. The car was fitted with the stock system and then data was logged in 4th gear to the redline. Then the Eventuri intake was fitted and the same method applied. The outputs show that the air mass flow with the Eventuri is higher across the entire RPM range - with a bigger difference at higher RPM where the restrictions in the stock system become more apparent. Furthermore the difference between the ambient temperature and the inlet air temperature (IAT) is also smaller with the Eventuri due to the scoop enabling a higher air speed through the airbox. Here are 2 screenshots of the data output, one at approximately 5000rpm and the other at approximately 8300rpm.
Data Logging summary:
- 5000rpm IAT difference with ambient: Stock intake = 9.6 Degrees C : Eventuri = 5.3 Degrees C
- 8300rpm IAT difference with ambient: Stock intake = 7.6 Degrees C : Eventuri = 4.7 Degrees C
- 5000rpm Air Mass Flow Rate: Stock intake = 635 kg/h : Eventuri = 650 kg/h
- 8300rpm Air Mass Flow Rate: Stock intake = 1168 kg/h : Eventuri = 1202 kg/h

VBox Acceleration Tests
Finally we took the car for some road testing using a Vbox unit to record the acceleration from 60-130mph (also 100-200Km/h). For the Vbox testing our test car had a primary decat and stage 2 tune for all test runs. Testing was carried out on the same stretch of road - again on the same day to keep variables minimum. Results show that with just the intake added, the acceleration times from 60-130mph and also 100-200Km/h reduced by approximately 0.3 seconds which is a significant change at such speeds.
Acceleration results summary:
- 60-130mph with Stock intake = 11.157 seconds
- 60-130mph with Eventuri intake = 10.886 seconds
- 100-200Km/h with Stock intake = 9.56 seconds
- 100-200Km/h with Eventuri intake = 9.236 seconds
Who you are buying from
You are buying from a drift team, not a warehouse.
Our founder competes himself in his own drift E46. Our team build and race the same platforms you drive and work on, and our sponsored drivers chase championships on the same parts we sell worldwide.

We have already broken it for you.
Our founder, a full team of sponsored drivers, and hundreds of other drivers worldwide are out competing on this stuff in drift and rally. When we tell you a part is good, the part is good. It has already been put to the test.

Ordered before 1pm, fitted this weekend.
In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

Straight answers
The questions you were about to open a chat about.
How do I know it will fit my car?
Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.
“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025
When will it actually arrive?
In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.
If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.
Will I get stung for customs or import VAT?
No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.
What if I change my mind?
30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.
What warranty do I get?
Everything on our website is covered by the standard manufacturer's warranty.
If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.
Can I pay it off over a few months?
Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.
Can I just ask someone what to buy?
That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
