This is a power filter that was installed on an FTR. I changed it to a smaller one because I was concerned about the size after installation, so the mileage after installation was short, and I think the condition is good. It supports blow-by. I think the manufacturer was POSH, but my memory is vague. I think the condition is good, but it is a used item, so please refrain from purchasing if you are nervous. Please understand this point before purchasing. No claims and no returns, thank you.
