    MAP Limited Lifetime Warranty

    1.) All MAPerformance in-house fabricated parts include a Limited Lifetime Warranty for the Original Purchaser. This warranty only applies to the original purchaser and is non-transferrable.

    3.) You must create a support ticket to acquire your return authorization number prior to returning the product.

    4.) Warranty claims will not be honored if the product was not purchased through an approved dealer.
