Performance increase = 10-15hp, 8-12ft-lb
The E46 M3 intake system is a result of extensive data logging, dyno testing and design optimisation. The aim was to develop an intake system for the S54 engine which worked with the stock ECU map and MAF sensor and produced a genuine improvement in the driving experience.
The Eventuri Difference
The E46 M3 Eventuri system uses Eventuri's Patent Pending Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.
PERFORMANCE
Below is a dyno graph showing the comparison between the Eventuri and the stock airbox on a standard car with just a rear exhaust and standard map. As you can see, power and torque are increased through a large portion of the rpm range not just at the peak. 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.
Although the Eventuri system does not require a remap – we have seen further gains when the E46 M3 is subsequently remapped. The graph below shows another E46 M3 with 3 curves – stock, Eventuri and then Eventuri with a remap. In this instance the car was remapped by Evolve Automotive.

PRODUCT DETAILS
Components
Each component is engineered for a purpose and to a very high standard. Each kit consists of:
Carbon Air Scoop
MAF tube
Heat Shields
- 100% Prepreg Carbon Fibre Intake Housing
- Anodised Aluminium inlet cowling
- High Flow Filter
- CNC Machined MAF tube
- 100% Prepreg Carbon Fibre Air Scoop with CNC machined aluminium collar
- 3 Aluminum heat shields
- High quality Silicon coupler with BMW specification hose clamps
- Made from 100% prepreg carbon fibre of the highest quality, the workmanship on the housing is second to none. This encapsulates the filter and is mated to an anodised aluminum inlet cowl to ensure a smooth inlet flow path. The filter itself is a deep pleated, high flow double cone configuration which is dry to avoid damaging the MAF sensor. Finally the assembly is then mated to an aluminium heat shield which effectively shrouds the intake from engine bay heat and captures the ambient air being diverted from the scoop. Also notice the rubber spacer on the mount of the heat shield - this is for the headlight module to sit on so that it remains at the right height - small details are important!
Carbon Air Scoop
- 100% Prepreg carbon fibre with a CNC machined collar - the air scoop forces ambient air directly into the filter opening. This scoop simply clicks into place in the front right hand brake duct and effectively saturates the mouth of the intake with cold air. It has been designed to take up half the height of the duct in order to allow airflow to still continue through the duct for the brakes. The scoop is so effective that even after a hard drive, the aluminium cowl at the mouth of the intake will still feel cold to touch!
MAF tube
- The MAF tube is CNC machined from aluminium and then anodised. The MAF boss itself is machined from an engineering plastic to minimise the heat soak into the sensor through conduction. We have incorporated a machined recess on one side to allow the OEM rubber gasket from the stock airbox to be used for a perfect seal into the stock elbow.
Heat Shields
- There are 3 aluminium heat shields. The main shield is part of the intake assembly as above. There is then an extension shield which fits onto the main shield and blocks hot air from the radiator. The last shield secures to the chassis underneath the carbon housing to minimise direct heat soak from the block. We used neoprene on the main shield to insulate it for optimum function in keeping inlet air temperatures as low as possible.
- These components come together to improve the efficiency of the engine intake. The result - more power, throttle response and sound.

Glad I Gave It a Try
Flavor Name: Orange, Size: 15 Ounce (Pack of 1), Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
I wasn't sure if this Metamucil fiber supplement would make much of a difference, but after taking it consistently, I'm really glad I decided to try it. The results weren't instant, but over time I noticed that I felt lighter, cleaner, and just generally better overall. The sugar-free formula is a nice bonus, and it's easy to make part of a daily routine. I've found that consistency is key, and once I started taking it regularly, I could definitely tell a difference. If you're on the fence about trying a fiber supplement, this one has worked very well for me. It's a simple addition to my day that has had a noticeable positive impact. I'll definitely keep using it.

It works.
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
It really does help 'keep you regular' & the name brand dissolves easier than the generic W@lm@rt brand. It doesn't MAKE you 'go', it just gives your gut a little something to work with, so to speak. Maybe TMI, but you also go alot cleaner, if you catch my drift. That's a nice bonus. ;0)

Great to curb food cravings
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
Saw this on a YouTube video for reducing appetite/curbing snack cravings and wow! I’m on day 2 and this will always be in my pantry. After 30 min of drinking this I feel sooo full. No appetite for 4 hours like I ate a huge meal. The flavor is also good. No cramps or gas and the fiber content isn’t crazy so I haven’t experienced any negative side effects either. If you’re trying to lose weight this may help. Haven’t thought about snacking all day. Give it a try
