Please note that racing filters of ANY type are built for minimum-restriction - meaning their micron size is much wider than a street filter. It passes big particles from the very start. This applies to all filters using a "flow-through" media.
It matters little how often you change your oil and filter. Racing filters are designed for engines that only have to survive a limited amount of time / miles between total rebuilds - NOT oil changes.
If you are a big NASCAR team (or equivalent) that routinely rebuilds their engines after every race - a racing filter is fine. If you are a privateer or small team that does not automatically rebuild, then I would not recommend a racing filter.
As a point of note, I have seen privateer outlaw racing teams that use standard WIX street filters with absolutely no problems or complaints.
