Hsv bimodal intake

[Super Coach]

ok, so is it worth buying this from planet parts and fitting to a Holden LS3? Is there any actual difference between the 2 products as mentioned?

or do you try and cut a hole out in the standard Holden part?

as stated it is not at all worth it. its supposed to help as a tuned air intake. OTR or bigger pipe and box (rotofab)
