I've got the K&N FIPK (filter and adaptor plate plus mounting hardware), and there is a difference in the more expensive brands. The JWT, the K&N FIPK, and other higher priced ones have the adaptor that has a tapered inlet into the intake tube so they flow better since the moving air is smoothed out as it enters the intake.
The cheap stuff on ebay usually have a 3" tube and is not tapered to funnel air in. There is usually a big difference in the prices between the expensive and the knockoffs, so it's all up to your budget restrictions.
