Fits 2019 BMW 330i G20
Thank you Blu-TSK, (DO IT YOURSELF) video on YouTube for recommending this product for my BMW 330i 2019, G20. I was a bit confused why the product had purple oil, and I went back onto this and looked at customer questions cause I was dumbfounded on why would there be oil on it. This product is amazing. My BMW on ECO PRO feels different than the OEM engine filter. On ECO PRO I feel less lag after releasing the Gas pedal and while driving on the highway, it has more acceleration merging onto the high way! On Comfort mode, it takes OFF! I hear my engine better now. Sounds amazing for a Stock 330i!

Buy it don’t think twice
Perfect fit with my car. Easy to install. Price seems like a steal seeing as it comes with a lifetime warranty. Cleaning is a cinch. Definitely noticed a small performance improvement, nothing to go nuts over but it’s there.

Fits 2024 Grenadier perfectly
It's a K&N so it works.... if you actually clean it and oil properly. I got this for my Grenadier as it has a B58 from a ton of BMW models. It wasn't showing for the Grenadier but I can confirm it fits perfectly

Solid replacement for disposable filters
Installation was a breeze. The filter fits perfectly into the existing airbox, making it a straightforward DIY upgrade for anyone with basic automotive knowledge. The quality of construction is evident upon handling—the materials feel durable and well-crafted. Performance-wise, the difference is noticeable right from the start. The K&N filter allows for improved airflow, which translates into increased power and responsiveness. Acceleration feels more immediate, especially during spirited driving or overtaking maneuvers. It's like unlocking hidden potential in your engine without compromising on reliability or fuel efficiency. Another standout feature is the longevity of the filter. Unlike traditional disposable filters, this one is washable and reusable, making it a cost-effective choice in the long run. Plus, it's backed by K&N's renowned reputation for quality and performance, providing peace of mind. In terms of maintenance, upkeep is minimal. Periodically cleaning and re-oiling the filter is straightforward, ensuring consistent performance over time. It's a small investment that pays off in driving enjoyment and engine longevity.

Super filtre pour ma G20
Super filtre adapté pour ma BMW MSPORT type G20. Là où je sens le plus sur le fait que l'entrée d'air est supérieure au standard est en mode éco.
