Since these engines are still new to the U.S market it looks like parts are rather limited and the supply chain inconsistent. Hopefully that will change soon. I stopped by my local autozone and asked about oil filters. I was quoted a price of $8.69. A quick phone search and i found them at rock Auto for 8.99. My company is somehow associated with Napa and i get a discount on parts, tools etc from them but they werent showing any. Please post where and how much you find them. Tryiny to keep osts down for all of us.
