Mitsubishi Evo 8/9 Aperture I Throttle Body by Works Motorsports

Another WORKS first original product imitated by others! There is a science to correctly sizing a throttle body and WORKS pioneered this product by investing countless hours of research into this area during the spring of 2003.

The result: a significant reduction in the pressure differential before and after the throttle body that can add 10+ horsepower to your EVO, smoothes out power curves, and pays even bigger dividends as you add other tuning parts. Just as important, the Aperture provides quicker throttle response. WORKS leaves no part of the EVO untested and the reward is real power out of a simple solution. Each Aperture features a "WORKS" engraved plate and is assembled and checked by hand for proper clearances.

When using an intake manifold with a 65+mm opening such as the WORKS ported AFM (Abrasive Flow Machined) intake manifold, use the WORKS "Max Bore" Aperture II throttle body. Comes complete and ready to install with Idle Air Control valve and WORKS calibrated Throttle Position Switch option, new OEM gasket, and Installation Instructions for hassle-free installation.


  • WORKS Aperture Throttle Bodies are always equipped with the WORKS Aperture High Pressure Shaft Seals
  • WORKS Aperture Throttle Bodies include an OEM Mitsubishi Throttle Body Gasket

Please Note: The Aperture I is sold on a core exchange basis and may vary cosmetically, but is fully functional. You send your core and sensors (if sensors are needed) once you place your order, and we will send your new Aperture I once we receive and inspect your core.
