It is a direct replacement for the factory plastic turbo inlet, which sits on the suction side of the system between the airbox and the turbocharger compressor inlet. Dinan's own install document names the application as the G2x M340i\/M440i LCI2, so check that your car is the 2025-onward Gen 3 B58 car before ordering: the earlier Gen 2 B58 cars use a different Dinan inlet.\u003c\/p\u003e\u003cp\u003eWhat the part actually changes is the internal shape of the flow path. The factory inlet carries sound resonator features that add restriction and turbulence; Dinan removes them and enlarges and smooths the passage, which raises intake volume and flow rate over the OEM piece and makes the turbocharger audibly more present. Dinan calls it a quick bolt-on and quotes roughly one hour of labour. Dinan does not publish an inlet diameter, a layup description, or a horsepower figure for this part number, so none are claimed here.\u003c\/p\u003e\u003cp\u003eDinan warrants its performance products for the remainder of the vehicle manufacturer's new-car limited warranty (up to 4 years\/50,000 miles) or for 2 years\/unlimited miles, whichever is greater. Dinan further states that while the vehicle is still covered by the factory warranty, it covers both a defective Dinan component and any original manufacturer component directly affected by it. Dinan also states plainly that installing performance products may affect the vehicle manufacturer's new-car limited warranty.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFits the 2025+ BMW M340i and M440i with the Gen 3 B58 (B58TU2) engine\u003c\/li\u003e\n\u003cli\u003eDirect replacement for the OE plastic turbo inlet\u003c\/li\u003e\n\u003cli\u003eDeletes the factory sound resonator features built into the OEM inlet\u003c\/li\u003e\n\u003cli\u003eLarger internal volume and higher flow rate than the OEM inlet, per Dinan\u003c\/li\u003e\n\u003cli\u003eCarbon fiber construction in place of the failure-prone plastic original\u003c\/li\u003e\n\u003cli\u003eBolt-on installation, approximately 1 hour labour per Dinan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2 style=\"margin:16px 0 4px 0;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"border-collapse:collapse;width:100%;margin-top:0;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eTurbo Inlet Pipe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eFits Engine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eBMW Gen 3 B58 (B58TU2), 2025+ M340i and M440i\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eCarbon fiber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eSold As\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eSingle turbo inlet pipe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border-bottom:1px solid #e5e5e5;\"\u003eRemainder of the vehicle manufacturer's new-car limited warranty (up to 4 years\/50,000 miles) or 2 years\/unlimited miles, whichever is greater (Dinan published terms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;\"\u003eDNND760-0079 (Dinan D760-0079)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"margin-top:12px;\"\u003eDocuments: \u003ca href=\"https:\/\/documents.dinancars.com\/655e313728e4bfec0fa18bbd9d28cd49de3a9d32.pdf\"\u003eInstallation Instructions (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":47083961188524,"sku":"DNND760-0079","price":319.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0480\/2160\/2467\/files\/ddbb177cab82734628578383093ff09bL.jpg?v=1787920053","url":"https:\/\/onefastshop.com\/products\/dinan-carbon-fiber-turbo-inlet-pipe-bmw-m340i-m440i-gen-3-b58-2025-direct-oe-replacement","provider":"OneFastShop","version":"1.0","type":"link"}
