We are having to face a sad reality regarding our previously well-received Aircooled.Net SVDA Distributors. We don't currently have any, and unfortunately, it is very possible that we will not be able to find any more of the Bosch distributor cores that we have used in the past to modify for use in specific carb applications. When VW of Mexico stopped manufacture of the old style Beetles, Bosch discontinued their manufacture of this compatible distributor. We have since been buying up any/all stock we could find, but our sources have been mostly depleted and we have been unable to procure more for approx the past 6 months.
We are now instead recommending the next best alternative which is the Pertronix brand 12 Volt SVDA. We've been selling these now for close to two years with good results and no major quality issues.

Aircooled.Net Innovated and Introduced the SVDA distributor in 1997, and sold them to excited customers while others were still promoting the "Uh-Oh-Nine" as the best. We have more experience with SVDA distributors on VW Engines than anyone in the World! Product Picture shows ACN SVDA with optional Points Replacement Device installed.
The Aircooled.Net (ACN) SVDA Distributor, or the Mallory Unilite, are our recommended distributors for VW engines. The ACN SVDA is our flagship product! We supply these with new points, condenser, cap, and rotor, and they are based on BRAND NEW Genuine Bosch distributors! This is a New OEM VW Distributor, we are NOT using Chinese Manufactured copies!
The combination of centrifugal and vacuum advance give the smoothest performance, a 3-4mpg improvement in your fuel economy on the highway, and a major drop in engine temps on the highway too!
Because we introduced this distributor, we coined the term "SVDA" in the mid/late 1990s to try to describe it. SVDA stands for "Single Vacuum Dual Advance" (since it has BOTH vacuum and centrifugal advance, that's where the "Dual Advance" comes from). The ACN SVDA uses the same cap and rotor as the 009, so you may even have some tune up parts lying around!
Starting with a brand new unit, we then re-curve them to OUR SPECS, depending on what induction you are using. We feel the ACN SVDA is the finest "stock type" distributor available for your aircooled engine. We shake our heads at how many other shops and repair garages are still promoting the 009 (We call it the "Uh-Oh-Nine"). We feel the only nice thing about the 009 is it's inexpensive and simple, so it's nice to "keep around" in case you have a distributor problem of some sort.
It's important to note that a Pertronix or Compufire for a 009 or 050 will NOT fit the SVDA, but a Pertronix or Compufire for an SVDA will fit the 009.
SVDA comes with points, cap, rotor, and condenser, but does NOT include the distributor o-ring nor vacuum hose. We recommend you reset the points if you are not installing a points replacement device.
We have had repeated inquiries about SVDAs for 30 PICT 1 and 30 PICT 2 carbs. There is NO SVDA compatible with the 30-1 or 30-2 carbs, so your options are to either put a stock distributor on, use a 009 (yuck), or put an SVDA on in conjunction with a Single Port compatible 30/31 carburetor, since we have an SVDA for the 30/31.
Great product, great service
