I've used those NPR ones in the first link. There are reviews on Honda tech etc and many reports of successful builds.

Mines in a b18c2, has done a bunch of track days without any issues. It never burns oil like it used to pre-build and feels like it picked up a few kw.

The castings seemed pretty good, but I have no idea if the teflon coating will last. It looks different to the oem coating on c7 pistons.

One thing to check is if they are USDM versions (I think p73AO?) because they have lower compression than the jdm. I think the Audm is the same as us anyway.

Just keep in mind they most likely won't be as durable as an OEM or forged pistons. So far mine have been good for a few years in any case.
