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!

Great Replacement Starter – Works Like a Charm!
Model: 10914
I recently replaced the starter in my 2015 Honda CR-V 2.4L, and the UCAREST 10914 Starter has been a fantastic upgrade. The fitment was perfect—it matched the OEM part numbers exactly, and installation was straightforward. It took no time at all to get it in, and once hooked up, the car started up instantly, no hesitation, no grinding sounds. The starter is solid and durable, and after a few weeks of use, I’m still impressed with how well it’s working. I’ve had no issues with it, and it’s performing just like the original one, if not better. The quality seems great, and it gives me peace of mind knowing I have a reliable part under the hood.
