Previously only available through purchase of an entire 2006 OEM airbox, ADOPT's induction horn is a lower-cost alternative that updates older DE airboxes to the 2006 configuration. \u003cbr\u003e\u003cbr\u003eB. \u003cspan style=\"color: rgb(249, 244, 216);\"\u003e[IN DEVELOPMENT]\u003c\/span\u003e S1\/S2 airboxes are only found on the extremely rare and Japan-only NISMO S1, S2, and Competition engines whose total number is perhaps 300 or less. S1 intakes use a heavily modified stock airbox to fit a tapered intake pipe and larger intake horn; 85mm at the airbox rather than 71.5mm as with standard models. S1\/S2 engines are high-RPM optimized; NISMO uses a tapered intake pipe to spread a weaker but wider-band VE signal gain across the rev range to mitigate loss of low end torque. Requires a tapered 85-\u0026gt;70mm intake pipe, to be released at a later time.\u003cbr\u003e\u003cbr\u003e\u003cem\u003eA drill is required to remove existing fasteners, which are replaced by provided Nylon hardware through the OE MAF mounting holes. Features a Buna-N O-ring at 25% compression, which seals the intake surface without need for a more cumbersome gasket.
