What secrecy?
Just because you can't find them in google, doesn't mean anything good or bad about them. You now know they are from CRD, how about you send them an email or a PM on here, or even get the time zones right and call them.
and for the record, I have one on my engine because Paul recommended it. We had a look around for the tomei or jun pump at the time but with the exchange rate, they were too expensive. Looks like a good choice so far for other people.
There is no such thing as a bullet proof component. If you are worried about your engine failing then don't drive a car or just baby it around. There are things you can do to help give you peace of mind, but at the end of the day there is a chance that something may fail.
