Improve your cooling with an
Awesome Powdercoat Venturi Ring!

You need a velocity ring (also called a volute ring, or just a cooling ring). This is an American made model of the factory fuel injected fan shrouds.

Cooling is improved by increasing the air velocity through the fan. The rings are all stainless steel construction, with spot welded mounting tabs and a satin black power coated finish. They can be installed on any factory or aftermarket doghouse fan shroud by welding, brazing or rivets.

A version for the early fan shroud is also available.

* Made in Ohio, USA
* All Stainless Steel Construction
* Works on all Doghouse Style VW Engine Tin
* Improved Engine Cooling

7.3% more airflow across the entire rpm range, at 4000 rpm, that is 800 extra cfm!

Venturi rings are also available separately,
so you can install them on your existing fan shroud.

Rings sold individually come in satin black
powder coat with 1/8" holes in the clips so
they can be welded or pop riveted into
place. Installation instructions are included.

Standard setup is for doghouse oil cooler, but can also be made to fit the early fan shroud (internal oil cooler) even the center  mount fan shrouds. The ring is the same, the mounts are different.

Prices are:
$55 for the ring alone, or added to any
shroud you buy from us.

All prices are + shipping.

Its a great product, all my VW's will have a ring."

It has made a huge difference in temperature reduction.  I have to race the vehicle, (in the 5000 rpm range sustained) to generate high temps at all."
