I'm not an expert in the field by any measure. Having said that, let me give you an example: when I installed the Tempest I got more or less a full 360 turn from initial contact of the seal with engine block till the filter was properly torqued. Not sure if Champion is any different in that aspect?"How far each O-ring sticks out" is not a measure of how effective the seal will be.
Why did Tempest and Champion design their filters with a big, fat, sticking out seal and not a fancy tiny quad ring?
