Tagging @CounterSpace Garage and @Jackson Racing, maybe they have some thoughts on the matter. I couldn't find any leaks last night.

There is a non-JR branded version of the filter availabe, and you'll also want to buy a K&N cleaning kit.

Thanks Mike. I already have cleaning kits for my motorcycle filters. I hate cleaning those things. Too much oil, too little oil...

Thank you Chris. Just replied to an email from tech@jr.

I believe the source of the problem was found. The bypass valve (diverter valve) does not hold vacuum. A buddy tested it at idle and found the valve lets unmetered air into the intake hose tee at the back of the intake manifold. Thats a decent air leak. FYI folks.

Had the same problem. Have you taken it off to look inside? Mine partially melted and bits of its plastic got into the valve, preventing it from fully closing. A few others have had the same issue. Jackson does not offer a solution but at least one person switched to an aluminum valve.

I wasnt able to see anything inside the unit out of the ordinary.

Is this a compatible bypass valve?

I think it's backwards. The bypass valve on the JRSC opens when there's a vacuum pull on the diaphragm, to prevent compressor surge on closed throttle. The one shown in the link looks like it opens at high pressure.

Thanks! Do you know any other compatible bypass valve? I want to replace my plastic valve with a metal one.

If that xspower diverter for Audi, Porsche is working for our JRSC kit, then the one I linked above at Amazon should also work. They are for the same cars.

Anyone have a recommended replacement bumper that fits better?

I've searched the thread, and I know people say it can be done with the stock resevoir, and I believe that's sometimes true... sometimes.

But it's not true with mine, hoping there's some options out there!

If it is not fitting, then you have the piping aligned incorrectly.
