Perfect fit, durable and affordable
Size: 9.5" x 10.9" x 2.1"
Ordered this for our 2023 Honda civic. Great fit, durable and very affordable. Was so easy to pull old one out and replace new one. Will be ordering again.

Save money by installing yourself
Size: 9.5" x 10.9" x 2.1"
Good price and easy to install in a 2019 Honda CRV. Instructions can be found on YouTube. Much less expensive than having a service center install them.

Always fits and is easy to install
Size: 9.5" x 10.9" x 2.1"
We've bought these for years and they always fit and are easy to install. Easy to see when they are dirty and need to throw away. Embarrassed that we let the car dealership do it for so long. We set on six-month subscribe and save so that we know when to replace it - change it whenever it shows up!
