{"title":"BMW 320si Parts and Accessories","description":"\u003cp\u003eThe BMW 320si is a rare E90 homologation special produced in 2006 to qualify BMW's works cars for the World Touring Car Championship. Fitted with a higher-output 2.0-liter N45 four-cylinder in a stripped, track-ready specification, only 1,000 units were produced, making genuine 320si parts and provenance documentation highly sought after.\u003c\/p\u003e\n\u003ch4\u003ePopular Upgrades\u003c\/h4\u003e\n\u003cp\u003eGiven the 320si's motorsport homologation purpose, owners favor period-correct upgrades: race-specification exhaust manifolds and cat-back systems, adjustable coilover suspension using E90-compatible strut and spring dimensions, and high-performance brake pads and braided lines appropriate to its track-oriented character.\u003c\/p\u003e\n\u003ch4\u003eWhat makes the BMW 320si different from the standard E90 320i?\u003c\/h4\u003e\n\u003cp\u003eThe 320si uses the N45B20 engine with revised internals producing 173 hp from a naturally aspirated 2.0-liter, versus the 150 hp N46 in the standard 320i. The body was also lightened with deleted rear seats and sound insulation on full homologation cars, with a reinforced front strut tower design for track use.\u003c\/p\u003e\n\u003ch4\u003eCan E90 320i parts be used on a BMW 320si?\u003c\/h4\u003e\n\u003cp\u003eMany E90 platform components including exterior panels, suspension geometry parts, and brake hardware are shared with the standard E90 320i. Engine-specific parts for the N45 differ from the N46 and must be confirmed by engine code, but chassis-level parts like coilovers, sway bars, and brake kits specified for the E90 sedan generally fit the 320si.\u003c\/p\u003e\n\u003cp\u003eSource the right parts for your BMW 320si at Black Ops Auto Works.
