K&N Oil Filter Warranty
K&N oil filters are warranted to be free from defects in material and workmanship. Any filter proven defective during the engine or equipment manufacturer's or during the oil supplier's recommended service intervals will be replaced at no charge.
In the event of an engine or equipment failure directly caused by a defective K&N oil filter, which was properly installed and changed following the engine or equipment manufacturer's recommended service intervals, K&N Engineering, Inc. will repair the damaged engine or equipment. If a full synthetic or other premium lubricant is used K&N will extend this coverage to the interval specified by the lubricant supplier.
Claims for engine or equipment repairs provided under this warranty must be submitted within 30 days after discovery of damage. K&N Engineering, Inc. reserves the right to examine the engine or equipment and filter to determine the amount of damage and whether it was caused by a defective K&N oil filter.
This warranty gives you specific legal rights. You may have other rights which vary from state to state.
Engine and equipment manufacturer's warranties remain in effect when K&N oil filters are used.
