I found an alternative air intake for our c43-its called needswings. Looks like a true cold air intake if you do a little modification. Just get some extra pipes/tubes to move it further in front of the radiator. Cheaper than renntech or kleeman too. Check out their website. They have a kit for slk32 and c32.

Needswings is a highly recommended vendor. Rob is an stand-up guy.

We already have a factory cold air intake, it's pretty good too! It picks up air flow just infront of the radiator, at high speeds it would have a small positive pressure too which aids top end power (you wont see this on a dyno).

The renntech air box is more about adding volume to the airbox and it seems to work quite effectively by all accounts.
