Perfect fit - had a slightly better square o-ring, diameter just a little bigger, allowed it to install easily and it sealed perfectly first try!Beware cheap ones! Use this Dorman version!

In the product information, it says 2 inches but it’s 2 1/2 inches very deceptive however the information said it would fit my car so I took a chance please update the info so that it’s correct thanks
