Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.

Wanting to correct my previous review (I reviewed the incorrect item). This product fit perfectly in my vehicle- my apologies for the first review; perhaps Amazon or the vendor can replace the first review with this one. I am very pleased with this item.
