Double stack- hold the cheese

[PowerDubs_imp]

Why would you want to buy something that does not work?

These made only the slightest gain over what the stock velocity stacks make once you bore them out.


To remove the stock velocity Stacks all you need to do is take the back half off the airbox.

To install these you need to remove the entire airbox and the entire throttlebody assembly from the cylinder head. You then need to modify the front half of the airbox to fit these in as they are larger. A whole lot more work for no benefit.

I already have a bigger camshafts.
