SFI maintains a quality assurance program for a wide variety of automotive aftermarket and performance products. This expansive catalogue of SFI specifications is used by many sanctioning bodies world wide. In this list, the number on the left is the SFI specification number followed by the product that is covered by the spec. The recertification period is the amount of time from the manufacture date when a product must be sent to the original manufacturer for inspection and then either recertified or replaced, based upon the findings of the inspection. Please note the time period shown is NOT the retest period for manufacturers. For more information regarding any of these specifications, please contact the SFI office.
