Korean-Brand (Hyundai Kia Genesis) Turbochargers Vehicle NO. Conventions
28231: The core Turbocharger Assembly.
28200: Commonly found on diesel turbo assemblies for older models or LCV, such as the Sorento, Bongo, and H1.
28235 / 39400: Turbo electronic actuator
2B / 2S Series (Small-displacement gasoline engines): Corresponds to Gamma (1.6T) or Kappa engines. For example, 1.6T turbo in the Tucson and Lafesta often follow the format 28231-2B760 or 28231-2S300.
2G / 2T Series (Mid-to-large displacement gasoline engines): Corresponds to Theta (2.0T) or the new Smartstream (2.5T) engines. Examples include 28231-2G410 and 28231-2GTA1 for the 2.0T in the Sonata, K5, and Santa Fe; the Genesis 2.5T uses part number 28231-2T000.
2F / 4A Series (Diesel engine platforms): Corresponds to R-series diesel engines (2.0D/2.2D) or D-series engines. Examples include 28231-2F650 for the Sorento 2.2T diesel version, and 28231-4A800 for trucks and LCV.
Technical Upgrades and Revisions: If only the final digit of the last five characters increases (e.g., changing from 28231-2G410 to 28231-2G420), it typically indicates that the OEM has made internal structural improvements to the turbocharger (such as resolving issues with sticking or oil leakage); the new part number serves as a direct, seamless replacement for the old one.
Presence of the Letter "A": Part numbers containing an embedded "A" or "B" (e.g., 28231-2GTA1) often indicate that the turbocharger is an integrated assembly that includes the exhaust manifold, or that it is a comprehensive assembly custom-designed for a specific mid-cycle facelift model.
