Save $150? Why not.
I recently purchased the K&N Engine Air Filter for my 2019 Chevy Traverse RS, and I couldn't be more satisfied with my decision. The fit was perfect, making the installation process quick and straightforward. One of the standout features of this filter is its reusability. The washable design means I won't have to worry about purchasing a new filter every few months, which translates to significant savings over time—about $150, in fact. What impressed me most about the K&N filter is its longevity. Being able to clean it every 75,000 miles is incredibly convenient and environmentally friendly. Instead of contributing to landfill waste, I can simply wash and reuse the filter, which aligns well with my efforts to adopt more sustainable practices. Performance-wise, my Traverse has never run smoother. I noticed an immediate improvement in engine responsiveness and fuel efficiency after installing the K&N filter. It provides excellent airflow, which is crucial for maintaining the engine's performance and health. Plus, knowing that this filter is designed to last for such a long period gives me peace of mind, as I won't have to constantly monitor and replace it. Overall, the K&N Engine Air Filter is a fantastic investment for anyone looking to enhance their vehicle's performance while saving money and reducing waste. It's a high-quality product that delivers on its promises, and I highly recommend it to all Chevy Traverse owners and beyond.

Purchased for 2020 Chevy Blazer
Have purchased a K&N filter for every vehicle I have ever owned. Pretty much always see at least 1-2 MPG improvement, and love I never have to replace them for as long as I own / lease the car. Also love the "growl" I seem to get out of the intake with these installed. Bought this one for a new 2020 Chevy Blazer RS with the 3.6L engine. It took longer to unscrew the lame screws on the airbox (they are long and tight) than to drop in the filter. On the Blazer the airbox cover is stiff and hard to pull off if you do not disconnect the intake tube with the mass airflow sensor on it, but I didn't take it off in this case (lazy). Filter dropped right in, perfect fit. Screwing back in the airbox cover screws was at least easier than taking them out- and glad I don't have to do it again. I also always put the sticker on the vehicle somewhere near the airbox so the dealership doesn't take out the filter, or try to say I need a new one when I know I don't (scam). On the Blazer there is a nice intake growl from the 3.6L. Would purchase again, love it, and great value. This doesn't say it in the description but it does fit the 2020 Blazer, I verified it on the K&N web-site.

Good value, works great
Since I first tried K&N years ago, I've been using them in all my cars. They work great. What's nice is they are washable and reusable, therefore saving money going forward.

If you find it on discount is always worth K&N
We all know this brand is great K&N has years with a high performance, its a lifetime filter totally worth it for most cars and is a high flow, Really easy to clean once the miles pass, I have the cleaning kit takes like 10 minutes and soft water, cars with turbos, is not a made for exactly sounding more, but you will definitely notice more the sound of turbo in most cars.
