Find Acura Integra parts for classic hatchbacks and sedans or the modern turbocharged liftback. Start with the model year, body style and engine, then distinguish GS-R, Type R, 1.5-liter turbo and 2.0-liter Type S applications. Compare exhaust systems, intake components, brake parts and accessories by their individual fitment notes. Classic Integra and Modern Turbo Applications U.S. Integra applications include the 1986–1989, 1990–1993 and 1994–2001 models, followed by the return of the Integra name for 2023. Body style and trim matter within those groups. A classic LS or RS intake is not automatically the same as a GS-R or Type R intake, and a sedan-specific accessory may differ from one for a three-door hatchback. The modern Integra has separate 1.5-liter turbo and Type S 2.0-liter turbo configurations. Transmission also matters: the 1.5-liter range includes CVT and manual configurations, while the Type S uses a six-speed manual. Identify the exact vehicle rather than using a clas...
