It depends on your definition of "good". If less restricted airflow is "good", then yes. Unfortunately, that lowering in restriction has also been known to allow more fine particles of dirt through than a paper filter - which defeats much of its purpose.It may be able to improve absolute top-end power, but that's questionable - and probably only measurable on a dyno. I used one for a while on my previous car (a Sunfire) - and although I thought I felt a difference at first - I suspect that the paper filter was in need of a change anyway. Once I had researched more and found out how much dirt may be getting through, I replaced it with a new AC Delco filter - and felt NO difference going back to paper.I would also be hesitant to use an oiled filter on an application that has a MAF sensor such as our Vibes. Although it shouldn't be over-oiled when new, if you clean it and re-oil it, it's a bit difficult to determine exactly how much should be on there.Personally - from now on I'll stick with good quality paper filters. If I was off-road racing where it may get wet, then I may consider something like a K&N again - but not for street use.That's my personal opinion anyway.P.S. - tests have shown that even a restricted air filter won't have much if any measurable effect on fuel economy either - so don't expect it to start saving you money at the pump. I can vouch for that with past experience on the Sunfire too. I tracked every tank from new to when I sold it (243,000km) - and it made NO difference. The fuel filter is a different story though...John

Iff you want less restriction, rip out the old box and put in a bigger air filter housing with some less restrictive intake lines.
