Nope never oiled the filter but I did clean it about a month ago. I just used compressed air to clean it out as best I could.

Hmmm. My MAF died as well after about 3k on my Eventuri. Strange. I installed a new filter and MAF sensor from FCP Euro. Next time it dies, it's covered under warranty. However, I might just buy the CSL intake from Streamline.

Let me know if I'm reaching with this thought or if it's plausible. I went through a touchless carwash today...as I was inspecting the car after the wash I remembered that the eventuri scoop holds water after a wash. So my theory is that could it be possible that the intake sucks in some of this water at speed and then over time could kill the MAF?

Obviously nothing major to hydro lock the motor but enough to mess with the sensor.
I'm just guessing but it hit me today at the wash lol.

Check ignition coils, maybe more than one is out but usually it'll run really rough with 1 gone. I've had over 8 go out on me during the 3 years I've owned my e46.

8!?!?

In 15 years and 200,000+ miles of e46 M3 driving, I've had 2 fail.

There was a bad batch at one point, that there was a recall for. I wonder if your car was in that and didn't get the recall done.

Don't run it below 50 miles range going forward. The fuel pump cools itself with fuel, so you don't want it to struggle.

I emailed Evolve to ask why a MAF would go out and they said it could if oil got into the MAF. Not sure how that can happen as the Eventuri filter is a dry filter.

As for the scoop, I don't have one. I don't know how plausible that is.

You not having a scoop throws my theory out the window lol.

I wonder if evolve meant oil from the ventilation hose in the air manifold?! That being said I recently replaced my knock sensors and my manifold was pretty dry; my intake elbow, charge pipe and maf sensor were completely dry. My car doesnt burn oil.

I'm wondering if maybe there was an electrical surge on the maf sensor that fried them.
