What's clearance like on KE70 for the 110mm Stacks? Except my car has engine mounted 2" forward, ill probably have to get some tape measure out.

[Sam-Q]

normally 70mm stacks come very close to the brake booster, 110mm normally be for left hand drive only. However in your case it might fit.

The combined filter adapter I am working on might fit as well.

[Tim.duncan]

hey sam do you do stacks for DCOE 40 dellorto carbs?

[Sam-Q]

I can if you give me the specs, haven't do so yet

[evil86]

any performance gains between the lengths of the stacks or is it just for fitment

[Sam-Q]

definate performance gains, 110mm seems to be ideal for both a 4age and beams
