At my first ever track day, my K&N Oil filter exploded down the back straight on the out lap of the final session causing me to crash. After doing some research, I found that I was not an isolated case. After seeing the negligence of K&N, I decide to go after them for my damages as a result of their negligence. This is the story of my interaction with their legal/warranty department. I hope this may help a few others.
I will have to state that from my experience that the warranty process was not so smooth and I had back to back failures of their product. I walked away with not a cent.
