I have to erase all cookies on iPadOS 13
Then open moparts webpage
Click on left hand Infolinks tab
Scroll down to the small colored “opt out” lettering, click it
This opens a new webpage with the Infolinks still there.
Now close the first two webpages.
Open a new fresh Moparts page and Infolinks will be absent.

But... if you visit
a non-Moparts webpage doing business with Infolinks
( americangreatness.com for example)
this new webpage you visited will over-write your prior cookies
Wipe out your opt-out cookie status
And your next visit to Moparts will have Infolinks all over again.
