Easy to install. I do not know yet how good they really are since I only have driven around 50 miles since I installed it. The proof will be with time to see if the engine performs any better and gets improved gas mileage.

High quality and easy installation, but filtering efficiency?

I just installed this filter & have not noticed any performance differences.I used one of these before for about 6 years in this car. After this installation, I researched & found that there are questions about how well these units actually filter. Even K&N seems a bit murky about filtering efficiency. In one good experiment/analysis, the K&N clearly let through more dirt than a Mazda factory air filter and one premium racing filter, but less than 3 others,so I'm not so sure now a K&N is for me.

THE K & N AIR FILTER IS MORE THEN I EXPECTED. AFTER THE COMPUTER ADJUSTED TO THE NEW FILTER MY MILAGE HAS GONE FROM 22MPG TO BETWEEN 27 AND 30. AMAZING RESULTS. I HAD USED THE FILTER BEFORE BUT NOT WITH SUCH RESULTS. MY NEW RIDE IS A 2008 CADILLAC DTS WITH ONLY 17,731 MILES AND IS RUNNING GREAT.

Good product

Superior to factory/dealer air filters

K&N air filter, Buick Lucerne

I put a K&N air filter in my 2008 Buick Lucerne, and I also had one in my old car, a 2001 LeSabre, which had over 230,000 miles on it. The stock filter in the Lucerne isn't paper, it's fiberglass. It's not very fine and not cleanable, either. The K&N filter is far superior in both filtration and airflow. The car seems slightly quicker and more responsive and the engine is getting cleaner air, which should help it last longer.

Great product

The k&n filter was easy to install. Just removed the stock paper filter and installed the k&n in the stock location. Gas mileage has gone up a little bit not a huge change but it is noticeable.
