Dear Hovovongila,

May this find you well. FCP Groton's free lifetime warranty applies only if the part is installed by as ASE-certified technician.

Others, who want that warranty, have to pay for it: "Product must be installed by an ASE certified technician. If the product is not installed by an ASE certified technician, FCP Groton does not provide a FREE limited lifetime warranty. FCP Groton does however provide the option of purchasing a limited lifetime warranty for non ASE certified individuals who plan to install the product themselves. The cost to purchase a limited lifetime warranty is 10% of the cost of the product. To purchase a limited lifetime warranty, please email warranty@fcpgroton.com."

Hope this helps.

Yours faithfully,

Spook
