Ever since the first E30 series came along, BMW M3 has enchanted car enthusiasts around the world. The E90 series, that has been with us a few years, is no exception.

It´s suitable for track racing, endurance racing, track days or inspired street usage, where there´s no room for compromise in terms of perseverance. This is one of the products in the history of do88 that has taken the most man hours to develop, which is clearly shown in the fitment, finish and performance.

Greater core volume, bigger active cooling area, that frankly is what actually cools the oil, excellent fitment and - of course - vastly enhanced performance, makes us guarantee you will be satisfied!

Great Cabin Filter Upgrade
Style: BE-729H 1-Pack, Style: BE-729H 1-Pack
I recently replaced my old cabin air filter with this one, and the difference was noticeable right away. Installation was quick and straightforward took less than 10 minutes with no special tools needed. What I appreciate most is the air quality improvement. The airflow feels stronger, and there’s a clear reduction in dust, odors, and outside pollution entering the cabin. If you’re looking for an easy, affordable upgrade that actually makes a difference in everyday driving comfort, this cabin filter is definitely worth it.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.

Great filter and easy installation
Style: BE-159 1-Pack, Style: BE-159 1-Pack
For my 2016 Hyundai Sonata Hybrid Limited. I cannot believe I paid so much more for a brand-name filter that does the same thing as this one. It is made of the same material as the dealer one I took out. Very easy to install, cant believe I paid for this to be done in the past with oil changes. Requires no tools and did not get dirty at all. No mechanical skills needed, especially if you run into trouble and can use YouTube. PROS - great quality, cannot tell that it is after-market - very professionally made, not irregularities seen - excellent fit in position, no adjustment needed - very easy to install, cannot believe I paid to have this done in the past - no mechanical skills needed to install - great price compared to what big name productions want for the same thing - cannot tell the difference in air quality between this and the dealer filter I took out - removes outside odor completely - did not require tools are getting dirty CONS - None

Fits perfect and works as designed. Flows like OEM and looks well made.
Style: BE-553B 1-Pack
This filter is very comparable to the stock filter. Fits the BMW G20 just like OEM. I would not say it is two times "heavier" as advertised on the box, but it is very comparable to stock. It's the same weight and similar construction. BMW has a very robust cabin filter. This will be my go to. I did purchase another aftermarket cabin filter that fit well, but was thin, flimsy and had a bad chemical odor. This one is fine and airflow is the same as OEM. I change them every year or so. I don't worry too much about longevity with cabin filters personally.
