The Mishimoto Performance Intake replaces the factory airboxes on the S58 engine with dual airboxes molded from 3K twill woven carbon fiber, cutting intake restriction 13% on the driver side tract and 22.8% on the passenger side. Two additional ports draw cool air from the wheel wells, and dual high flow oiled filters add surface area over the stock panel filters. The carbon fiber construction resists engine bay heat soak and amplifies turbo spool and bypass valve venting. It is covered by patent US No. 11,506,157 B2 and backed by the Mishimoto Lifetime Warranty.
