there are kits made for the swap. I don't know if there is better filtering in spin on's tho, there is better access to the filter element with a canister, and there is more SA of filter element with a canister. The filtering qualities really depend on the quality of the filter, not the type of filter, a good fiber element filter is going to be a lot better than a cheaper paper element filter, no matter if it is canister or spin on.
