I'm with you on that Rev, I've been wanting to try one out, but there's something that just seems unnatural about reusing an oil filter. I know they can be cleaned, but it makes me uneasy. I'd REALLY like to hear from a board member that's tried one. I know Daddy Fatsac got one and he posted that it looked like a really high quality product, but he was in the middle of restoring his Busa and hadn't ever given it a run test. I'm tempted to bite the bullet and try it out. I hate being the lab rat though
