Surely and decent mechanic can fit those and charge a hell of a lot less?
Ive never used these specialists always used a local garage with a mechanic i trust and charges £20 a hour!! Hes worked on all my cars ranging from Imprezas to all the type r' under the sun and even my old range rover
Does changing the pipe to a alloy one (from the standard rubber one, keeping the OEM airbox) change the noise ? Or is that only affected depending on the airbox, open cone etc??
