[Zmagnette] Stub stacks

[Steve C.]

A stub stack is a short velocity stack. They increase and improve air flow into the carburetor. Pancake filters are not desirable from sn air flow stand point at all. The stub stacks will help if they are not too thin. The bigger the air filter the better with or without stubstacks.

What is a stub stack? Would it allow for a filter that lies closer to the engine than a regular pancake filter?

I've always just used the item #54 from the Moss catalog: http://www.mossmotors.com/Shop/ViewProducts.aspx?PlateIndexID=28996#top  Are these from APT or Rimmer better?


Always anxious to learn...

Hi everyone,

I'd like to get a pair of 1.5" H4 stub stacks and I've tried emailing Steve Ash several times to see if he would make some more, but I haven't got an answer from him.

So... from a light scour of the internet there appears to be two types available at a reasonable cost:
$32.50 ea - http://www.aptfast.com/ShowItem/101221%20Billet%20Alloy%20Stub%20Stack%20SU%20HS4.aspx
$57 pair - http://www.rimmerbros.co.uk/Item--i-RL1396ALT

I've excluded the K&N ones as they are very rough, by all accounts.
Are there any others that people would recommend?

They're going to fit inside K&N filters that are 2 1/8" thick.

regards,
