Where did you get the valve?

Air compressor tool/accessory section at Lowe's.

What size threads?

HellifIknow! The threads and IDs and ODs of how things are measured don't always makes sense to me. Does 1/4" NPT sound legit? I unscrewed the broken petcock and thought the threads and size looked familiar so I grabbed a fitting from my air compressor stuff and it threaded right into the catch can. This is what I got:

It isn't pretty, but it works. Like I said, I didn't get the adjustment exactly like I would have preferred due to being in a rush because of a rain shower. The more I think about it, I'm not even sure I'll spend the time/money to paint or coat it since that doesn't impact the functionality. Isn't like anyone looks under the hood or I'm taking this thing to car shows. LOL As previously mentioned, it's definitely louder than the stock setup, not in a bad way though, and certainly seems in the 30 or so miles I've driven it so far that it takes a bit less pedal to moderately accelerate and cruise. More crisp/responsive throttle. I've got a full week of work commuting ahead and then a 800 mile round trip road trip this coming weekend, so I'll be able to tell soon what impact (if any) it has on fuel mileage in both scenarios.

Planning to still stay on the lookout for a smoking deal on an Airaid tube, but for now this works just fine.
