I currently run a Magnefine filter on my Echo and Rendezvous. In Canada the only price I can get them at is $37.50 CAD on amazon.ca. I did find some Chinese replicas on ebay.ca for ~$16 CAD. Here are some side by side pics, they are nearly identical. The proof is in the pudding though, I will cut them open after being used for approx 40k kms. It will take me a couple years to get to that point though, has anyone seen or used these Chinese knockoffs?
