I paid with my 28 Degrees credit-card linked to PayPal so I'm taking the xe.com rates. If you let PayPal due the conversion for you it will cost a few bucks extra.
Part no. is 70017-AM007.

I think any performance gains will be minimal in my ES but the dealership usually charge about $55 for the regular Mitsu filter anyway.

Enjoy this Black Friday deal.
