As i said before i do not have that lag with my SRI as it does not have the dual inlet.

Where it is located in the base of the filter i have a plastic cap (brand name).

But as aaron has mentioned it is best to have it enclosed or semi enclosed as you do not have the hot temp from the K series engine sucked in and draining it's potential power output.

If you have a CAI piping feeding the SRI it's a good choice plus implementing a casing to it is even better.
