Never said it retained the full Ford factory warranty. What I said it it was covered by FRPP 3/36 warranty.
Per the FRPP website:
Performance Packs and Components are warranted for factory-supplied material or workmanship, when installed on a late model Ford vehicles by an authorized Ford or Lincoln Dealer or Shelby Automotive, Inc, beginning upon dealer installation and registration of the part(s) with Ford Racing for the balance of 3 years or 36,000 miles / 60,000 kilometres, whichever occurs first, from the start date of the manufacturer's New Vehicle Limited Warranty. This Limited Warranty replaces the existing manufacturer's New Vehicle Limited Warranty for engine, driveline and suspension parts when a concern is triggered by a warranted Ford Racing part. This Limited Warranty replaces the existing manufacturer's New Vehicle Limited Warranty for engine, driveline and suspension parts, when the warranted Ford Racing Part is identified as the causal part of a warrantable concern. Installation of these select Ford Racing parts by an authorized dealer does not nullify the New Vehicle Limited Warranty. All engine, driveline and suspension warranty issues not related to installation of Ford Racing parts remain subject to existing manufacturer's New Vehicle Limited Warranty.
