Either way. The OEM filter has no end caps. The F-Sport, Wix XP and maybe a few others have end caps. However, most don't. I've run both, but have now settled on the WIX XP. AFAIK, Lance has settled on the OEM 041542-51010 stock OEM filter. K&N's web site shows the filter with no end caps:
Though some of the smaller illustrations show it both ways

Lou,
Sorry if I missed it somewhere, but I remember you being a big proponent of the YZZA4. Was there something specific that made you switch to the WIX XP?
^^^^Yep, I was. But, doing more research over the course of time and specifically this post changed my mind:

Daniel is an expert in the field of lubricants. Sadily we won't be hearing more from him in this forum - He now drives a Tesla.
And, I never recommended the YZZA4 per se, in the past I said that IMO, the YZZA4 was equivalent to the 51010, and there was no need to spend the extra money. I still feel that way if you want to use a Toyota OEM filter.
It's all preference. Your car will run just as long with any of these filters as long as you are changing them properly and often. I change oils and filters every 3k miles. I use the K&N as well.

Has the issue or question of oil flow (or resistance to oil flow) ever came up with high performance oil filters?
I have used the K&N oil filter before, but was wondering if the superior filtration of the WIX XP filters would be more resistant to oil flow compared to the K&N? Thoughts on this guys....🤔
