Description
Air filter stub stack specially made for DB2 Vantage to MkIII 1.75" SU carbs, the 4 bolt type, similar to K & N's original solid cast alloy Stub Stack as fitted to performance SUs for other classics.
The Stub Stack fits inside your original AML Vokes air filter casing & bolts up to the face of the carb (over the lip) using the original 3/16" studs & new spacer tubes. An inexpensive item that improves performance especially when using Aston Service Dorset's K & N replacement air filters as shown in the photo.
Price per Stub Stack
Note:
With all the talk about how to get the best performance from your Aston it only seems natural that perhaps optimizing what you have is the basic first step. The addition of a "stub stack" within your K&N filter is one of the simplest & cheapest ways to improve performance. The principle is that the more air you get into the chamber, the denser the charge, the greater the chances of increased horsepower! These stub stacks from Four Ashes based on the original K&N design do the job and easily fit into the AML Vokes filter casings.
As they are a large cast blank they can also be machined to fit larger carburettors (for other Classic's ?) upon request.
Please note that you may have to change your needles to the rich type listed by SU.
Developed from an idea by Chris Adams & Dave Jack of Aston Engineering whilst dyno testing a 2.750cc DB2 engine.
