What is the advantage of using this product? For a WRX model it increases the height of the hood scoop and when used in conjunction with an appropriate air duct (splitter) can increase the efficiency of the intercooler and reduce the temperature of the intake charge.

What is the correct splitter to use with this hood scoop? If you are using an STI intercooler (JDM or USDM) or an aftermarket intercooler with a similar core size (and location in the engine bay) then the corresponding STI air duct (splitter) kit that we offer should be used. If you are using a WRX intercooler you should use either your original air duct (and the scoop will be primarily a cosmetic upgrade) or use an aftermarket item such as from Zero Sports.
