Filter from my Elise S/C. ~2,000 miles, ~13 months w/ Redline 5w-40. Nothing in the pleats. Filter appears very well made w/ a thick canister, dense and even pleats, fairly thick media, plastic 'stiffeners' top and bottom and a metal tube. ADB and relief valves were still very flexible. Made in China. Makes me feel a bit better about paying the silly price for OEM.
