Improved and reliable.
Installed on 2021 Supra 3.0, nice drop in fitment. Hard to go wrong with K&N, came out of the bag nice and oiled. Changed my exhaust note when in sport mode, a bit more pops and turbo noise that may not be for everyone.

Must have for B46 BMW engine.
Great drop in replacement, immediate difference in sound. More turbo noise and about a 1mpg increase in Miami climate. worth it over the paper originals. I put a K&N in every car I own.

Boost Performance with a Reusable Filter
The K&N High-Flow Engine Air Filter (model 33-3136) is a popular aftermarket upgrade for BMW owners (compatible with select 2019-2025 models) looking to enhance their vehicle's performance and potentially improve fuel economy. K&N is a well-known brand in this space, and their filters are designed to offer increased airflow compared to standard paper filters. 💨🚗 The main promise of this filter is an increase in horsepower and acceleration due to the less restrictive design, allowing the engine to breathe more easily. A significant advantage is its washable and reusable nature. This means that instead of replacing your air filter regularly, you can clean and re-oil this K&N filter, making it a "lifetime" filter that can last for the entire lifespan of your vehicle with proper maintenance. This can lead to cost savings over time. It's marketed as a premium product, and installation is typically straightforward, designed to fit directly into the factory air box without modifications. While the performance gains might vary depending on the specific vehicle and driving conditions, many users report a noticeable improvement in throttle response. It's important to follow K&N's cleaning and oiling instructions carefully to ensure the filter continues to perform optimally and protect your engine. For BMW owners looking for a simple bolt-on upgrade that can offer a modest performance boost and long-term reusability, the K&N 33-3136 is a solid choice. 👍

Amazing quality!
Amazing quality, greased it up perfectly for my cars standards. Super happy with basically lifetime air filter I don’t live anywhere super dusty or park my car under trees etc so I expect it to go for a long time! I got a 2020 G20 330i and it was literally 3 clips pull and replace!
