Can someone tell me whats the difference between the automatic and manual versions of the alta airbox for a r53? They look the same..saw a good deal on a automatic one..

 

Figured it out...none

 

I believe the difference is only with the silicone tube

 

Yea. The tube will have 2 ports if automatic and one port if manual.

 

That is correct, the box is the same between the auto and the manual. Sorry I didn't see this earlier. If you have a manual, you can purchase the automatic version, and it will be a good upgrade over stock. You can also add the silicone hose later if you want as well. Thanks guys!
