I decided to switch over to the modern OEM paper element air cleaner because, it is safer without potential for oil leaks onto a hot engine and I am tired of cleaning the messy oil bath air cleaner.
It needed an new thermo-switch valve 035-129-630/B to get the warm air dampner flap in the air inlet of the plastic air cleaner working to help the engine run smoothly in cold weather.
Used OEM plastic paper element air cleaners might be available at airheadsparts.com .
The part number is 035-129-630/B.
It is an OEM VW part. It is available at

I ordered one the other day and it arrived yesterday July 14 2016.
I live in sw Oklahoma. It came from England.
It cost me
Order Date: 10-Jul-16 10:33 PM
Goods Total: £ 43.75 GBP
Carriage: £ 21.35 GBP
VAT: £ 0.00 GBP
Order Total: £ 65.10 GBP
That converts to $84.28 US Dollars.
There was an additional charge made by them without my permission of $ 0.85 US Dollars by VWHERITAGE but, I thought that was OK.
I could have gotten it from this place for about $10.00 more:

There is a more economical alternative that might work. It is this part:
Air Charge Temperature Sensor-Intake Air Temperature Sensor fits 01-07 V70 2.4L or
BWD Intake Air Temperature Sensor WT5610 for about $20.00 US Dollars available on eBay.
I ordered one of those to use as a spare.
It has the same dimensions between the tubes as the 035-129-630/B except the metal brass looking tube on the cheapie has a smaller inside diameter than the same tube on the 035-129-630/B and I have not tested it yet.
Also the two tubes on the less expensive option are a little shorter.
According to eBay that part will not work on my 1973 VW Beetle's air cleaner but, I think it will.
There was one more part I ordered for the OEM paper element plastic air cleaner. It is this:
OIL FILLER WITH CAP WITHOUT TUBE FITS VOLKSWAGEN BEETLE TYPE1 BUG 1973-1974
I bought it on eBay.
It is necessary so the special emissions hose from the plastic air cleaner will fit.

Note: I tried the hose I listed above but, it did not fit. This hose did fit:

Without that new oil filler breather part I had to plumb in the breather hose and it just did not look right.
I drove it around yesterday November 3,2016. When I got it home I felt the top of the pre-heat hose and the top of the air cleaner. They both were warm. I guess that means the new thermo-switch is working.
I am just trying to help.
There may be a better way of doing this.
