{"product_id":"stage-2-turbocharger-upgrade-1","title":"Stage 2 Turbocharger Upgrade","description":"The Blaast K04-015 is a stage 2 turbocharger upgrade engineered for 1.8T Audi A4 and VW Passat models, aiming for MAJOR POWER improvement.\n\nThis turbocharger utilizes some of the largest turbine and compressor impellers available, featuring advanced technologies such as extended tip compressor wheel technology and full disc inducer turbine wheel technology. The compressor impeller measures 45.1 x 59 mm, significantly larger than OEM K03 (36 x 50mm) or TT-225hp (42.5 x 55mm) units. Its turbine impeller is sized at 44.5 x 50mm x7.5mm, also larger than the OEM K03's 40 x 45mm dimensions. These specifications contribute to excellent low-end response and spool-up, making it streetable, while delivering STRONG Top-end POWER with good torque sustained through redline, even at 20+ psi.\n\nThis unit is designed as a DIRECT BOLT-ON, though a hi-flow air inlet tube is required. To fully exploit the potential of this turbocharger, ECU tuning and bigger injectors are necessary.","brand":"Blaast","offers":[{"title":"Default Title","offer_id":52687129444664,"sku":"K04-015","price":749.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661662985.webp?v=1784880669","url":"https:\/\/store.motormia.co\/products\/stage-2-turbocharger-upgrade-1","provider":"MOTORMIA","version":"1.0","type":"link"}
