2006 Honda Accord Air Filters

I wouldn't say significant performance improvement, but definitely noticeable, especially in 30-60 acceleration. It's nothing special going straight from 0 to 30, or 0 to 45, but it does do a good pull with the 30-60 and onward. I can only imagine that this is because of the rush of air that the intake starts to get at that speed. So it's worth the money for that alone. As for actual filtration, I'd say it's about on par with the stock filter, maybe a little worse. I don't live in a dusty area, but if you do, it's something you should consider.
