I bought a Tusk SS oil filter for my 2008 yz250f. The pn on the box is1379690006, but it's written on the box in pen, which is weird. Anyhow, pulled out the old filter and it doesn't look like the new one at all. The OEM has a rubber gasket on both sides, the SS only on one side and it's smaller in diameter, but the tusk filter came with a round red piece of foam? The ss one is different on one end too, it has a ball bearing you can push in. Here's some picks. Is it a different design, but works, or is this the wrong filter?
