I'm with rottenron on price being an issue. I replaced mine at about 170,000 kms and got an OEM pan pretty cheap. It's an issue of price and function. The OEM pan doesn't have a replaceable filter, but the number of magnet locations were more than some aftermarket I looked at. Let's be honest, unless you are a frequent changer who hot shots and put on plenty of mileage thus changes, you aren't going to be swapping this pan out very frequently. Most of the pans I looked at had comparable volume but some were deeper(heat problems, not me), all fit, so I went with OEM at a cheap price. Will change in another 170,000. To each his own.
