Turbocharger

The OEM Mazda L33L-13-700B is a direct replacement turbocharger engineered for specific Mazda applications, primarily the CX-7 model. It is constructed with a 5+5 blade billet compressor wheel (50.4 mm / 60 mm) and a 46 mm / 51.5 mm turbine wheel, designed to work with the 2.3L engine. While listed with OE codes L3Y4-13-70Z, L33L-13-700B, L3Y5-13-70Z, L3Y6-13-70Z, and L3Y4-13-70ZC, it is explicitly stated that this part DOES NOT FIT the 2020 Mazda CX-9. It also does not fit the 2007 Mazda B3000 or 2007 Mazda RX-8, despite some listings suggesting otherwise. Ensure compatibility with your specific vehicle before purchase. This turbocharger is also referenced as KKK K0422-581 and K0422-582 in some aftermarket contexts, and supersedes part number L3YC-13-70ZA. As a critical engine component, professional installation is recommended to ensure proper function and prevent further engine damage.
