Just worth noting, the 1995 VR6 doesn't suffer from the DI intake valve deposit issues, which plague later engines.
Anyway, the dyno results are something to look froward to.
Widman has plenty of bad UOAs from people monkeying with the air filter. 100x normal wear rates is alarming....

I think about all of the K&N users who never do a UOA, it seems risky. It's not like I am imagining it. I also DNL guys who change their air OE filter excessively. Few seem to appreciate the downsides.

An "oil bath" filter is not the same as a K&N and should not be used for comparison. The downsides of high-flow filters have been way over-played vs. UOAs like mine that show no issues at all and all the people that run them with no drama over years of service. In my car, a high-flow filter (K&N, AFe dry, etc.) when combined with other intake modifications to the OE setup have proven to replicate the noise/power benefits of aftermarket intakes when running performance software. And for that reason, I run one.
