In Reply to: Evo Air box Upgrade question posted by steven on November 24, 2000 at 17:34:57:

I have a 1991 M3 and I just purchased the Evo box and the Tow Hook covers. I have yet to install them.
My question is this:
Will I still use the ducts that are closed with the tow hook covers? If they wont be used then how does the box receive air? Should the airbox be "pluged" into the duct next to the radiator althought the ducts are blocked by the tow hook covers?

Thanks alot.

With a '91 M3 you should alreay have the Evo box unless someone either took it off or put on a cone filter.

Yes the box is "plugged" to that duct, there should be a foam sealing ring with the kit. It is a really loose fit, allowing the engine to move w/o breaking the box.

The evo box doesn't take air from the tow hook covers so it is OK to use the euro ones. It takes air from behind the bumper.
