Yes it's more expensive than disposable filters but it's better quality and I always bought the stock Nissan filters which were overpriced anyway. Best part is these don't go into the landfill. Can't say there's any noticeable performance improvement. I'm sure if you are replacing a filthy filter you'll notice a difference. If you want performance you need to go with an aftermarket intake system AND an improved air flow filter.
