Game changer for my truck
Size: 1.9" x 9.9" x 11.4"
I installed this K&N Lifetime Cabin Air Filter in my 2016 F-150 and noticed the difference right away. The airflow is stronger, and the cabin smells fresher even when driving through dusty or humid areas. What I really like is that it’s washable and reusable—so I won’t have to keep buying filters every year.
Fitment was perfect and install took under 10 minutes. Just pop out the old one, slide this one in, and you’re good to go. It feels solid and well made, not like those cheap paper ones. It’s definitely worth the investment, especially if you drive a lot or have allergies.
Highly recommend for anyone with a Ford or Lincoln vehicle—it pays for itself quickly!

nice quality
Size: 1.9" x 9.9" x 11.4"
I happen to be a fan of K&N air filters. Fit perfect in my vehicle. Seems like a much nicer quality filter than the cheapo filters from the parts store.
