TEGIWA Carbon Airbox. This S2000 Airbox is a proven design and manufactured from carbon fiber. It gives excellent performance gains over OEM S2000 setup and a lovely induction noise, the kit also looks great in the engine bay! It is supplied complete with all fixings/brackets for an OEM quality fit. The filter is cotton mesh and should replacement filters be needed in the future we will always have them in stock. This intake is likely to give you between 5-10bhp without mapping. To install this airbox part of the framework/skeleton from the underside of the bonnet will need to be cut away for clearance unless you already have a Mugen style bonnet.
