I bought another cleanable oil filter for my engine, this one is much smaller and wont interfere with the oil pump pick up line, I bought it from Bob Mazzolini Racing. it's expensive but I sold my System 1 filter for $100 so that made it easier to swallow. It is really trick. it's machined from billet and comes with a socket to install & remove it. Id say the only draw back is it will reduce the total oil capacity of the engine.
