Injen produced the world's first tuned air intake system and holds four patents covering the intake tuning process, including MegaRam (MR) Technology (patents 7,359,795 and 7,669,571) and Air Fusion (patent 7,721,669). Both are built into this SP1121 short ram system for the N52-powered BMW 1 and 3 Series.\u003c\/p\u003e\n\u003cp\u003eThe heart of the kit is a mandrel-formed 6061-T6 aluminum intake tube that gives the engine a smooth, uninterrupted path to the throttle body in place of the restrictive factory airbox. Injen developed the tube geometry on the dyno to deliver up to 12 horsepower and 11 lb-ft of torque while holding a safe air\/fuel ratio across the whole power band, so no additional tuning is required. A custom heat shield built specifically for this application keeps the filter separated from underhood heat.\u003c\/p\u003e\n\u003cp\u003eAir is drawn through a fully serviceable Injen SuperNano-Web dry filter, which adds filtration surface area for greater airflow without an oiled media. The result is a noticeably more aggressive intake tone under full throttle. This kit is made in Pomona, California and carries the Injen Technology Limited Lifetime Warranty.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSeries: Injen SP short ram air intake system\u003c\/li\u003e\n\u003cli\u003eDyno-proven gains of up to 12 hp and 11 lb-ft of torque\u003c\/li\u003e\n\u003cli\u003eIntake tube: 6061-T6 aluminum, black finish\u003c\/li\u003e\n\u003cli\u003eInjen offers this intake in multiple finishes\u003c\/li\u003e\n\u003cli\u003eFilter: Injen SuperNano-Web dry air filter, 3.5\" inlet, fully serviceable\u003c\/li\u003e\n\u003cli\u003eReplacement air filter part number X-1021-BB\u003c\/li\u003e\n\u003cli\u003eOptional Hydro-Shield pre-filter part number 1037BLK or 1037RED\u003c\/li\u003e\n\u003cli\u003eIncludes an application-specific custom heat shield\u003c\/li\u003e\n\u003cli\u003eFeatures Injen's patented MegaRam (MR) Technology\u003c\/li\u003e\n\u003cli\u003eFeatures Injen's patented Air Fusion Technology\u003c\/li\u003e\n\u003cli\u003eMaintains factory air\/fuel ratios; no additional tuning required\u003c\/li\u003e\n\u003cli\u003eCARB EO # D-476-8\u003c\/li\u003e\n\u003cli\u003eCARB EO # D-476-8 applies only to the 2006 BMW 325i\/xi, 2006 BMW 330i\/xi, 2007–2011 BMW 328i\/xi and 2008–2011 BMW 128i\u003c\/li\u003e\n\u003cli\u003eCARB EO # excludes all SULEV vehicles, including emissions test groups 7BMXV03.0N51, 8BMXV03.0N51, 9BMXV03.0N51, ABMXV03.051R and BBMXV03.051R\u003c\/li\u003e\n\u003cli\u003eMade in Pomona, California, USA\u003c\/li\u003e\n\u003cli\u003eInjen Technology Limited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Intake tube\u003c\/li\u003e\n\u003cli\u003e1 x 3.5\" SuperNano-Web nanofiber dry filter (#1021)\u003c\/li\u003e\n\u003cli\u003e1 x 3.25\" x 3.50\" step hose (#3140)\u003c\/li\u003e\n\u003cli\u003e1 x Heat shield (#11041)\u003c\/li\u003e\n\u003cli\u003e1 x Rubber bulb trim, 8.5\" length (#6058)\u003c\/li\u003e\n\u003cli\u003e2 x #56 hose clamps (#4005)\u003c\/li\u003e\n\u003cli\u003e2 x M4 x 16 mm button head screws (#6072)\u003c\/li\u003e\n\u003cli\u003e2 x M6 flange nuts\u003c\/li\u003e\n\u003cli\u003e1 x 5 mm vacuum cap\u003c\/li\u003e\n\u003cli\u003e1 x 6-page instruction sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Injen specifies no additional hardware, tuning or fluids for this intake — all required mounting hardware is supplied in the kit.\u003c\/li\u003e\n\u003cli\u003eInstaller-supplied tools: metric socket and wrench set, flat and Phillips screwdrivers, a trim panel tool and a torque wrench.\u003c\/li\u003e\n\u003cli\u003eOptional service items: Injen replacement dry air filter X-1021-BB, Injen Hydro-Shield pre-filter 1037BLK or 1037RED, and an Injen dry-filter cleaning kit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/injen-sp1121-installation-instructions.pdf?v=1787176832\" target=\"_blank\"\u003eInjen SP1121 Installation Instructions (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003esl-note: Fitment years above follow Injen's official application listing, which extends coverage to 2013 for the 128i and 328i\/328xi.
