De restricting the air box on my 1.6 SXI astra Ecotech engine.
im thinking about gettin Dbilas flowmaster system. i think its a whole new inlet manifold, which should de restrict the airbox yes?
How much more power does this give me a lad who works with this engine and has Cammed his sed im lookin at about 30bhp increase with an exhaust and a slight remap to let the ECU know how much more air its gonna be getting.
Will it be noticable?
