Kan. Stat. § 50-662
No person who prepares an estimate of repair shall specify the use of after market parts in the repair of a motor vehicle without disclosing the intended use of such parts to the owner. In all instances where after market parts are intended for use, the written estimate shall clearly identify each such part as being an after market part, and a disclosure document containing the following information in 10-point or larger type shall appear on or be attached to the owner's copy of the estimate:
"THIS ESTIMATE HAS BEEN PREPARED BASED ON THE USE OF ONE OR MORE AFTER MARKET PARTS SUPPLIED BY A SOURCE OTHER THAN THE MANUFACTURER OF YOUR MOTOR VEHICLE. WARRANTIES APPLICABLE TO THESE PARTS ARE PROVIDED BY THE PARTS MANUFACTURER OR DISTRIBUTOR RATHER THAN BY THE MANUFACTURER OF YOUR VEHICLE."
All after market parts installed on the motor vehicle shall be clearly identified on the estimate of such repair and are subject to the provisions provided by the disclosure. The installer of the after market parts shall be responsible for the negligent installation of such after market parts.
