{"product_id":"w-4-turbo-upgrade","title":"W.4 Turbo Upgrade","description":"The Weistec W.4 Turbo Upgrade represents a significant advancement in performance for the Mercedes M157 engine, serving as a complete replacement for the factory turbochargers. To complement these powerful turbos, the system includes entirely new intake tubes, with Weistec Carbon airboxes available as an optional upgrade. The accompanying Weistec Turbo-Folds are designed to enhance exhaust gas flow considerably over stock manifolds, while the Weistec M157 True Downpipes ensure a smooth, unrestricted path for exhaust gases exiting the turbine.\n\nThis engineered solution is capable of producing 1000+ crank horsepower on 91 octane pump gas when paired with supporting upgrades such as the M157 ASV\/Water-Methanol Injection System, Weistec True Downpipes, and ECU tuning. Impressively, these power figures are achieved at a controlled 20psi of boost. For enhanced reliability at extreme power levels, the Weistec W.4 ECU Tune manages boost, tapering it up with RPMs to maintain wheel torque under 800 lb-ft, thereby minimizing stress on engine components. With a fully built M157 engine and other supporting modifications, the turbochargers have the airflow capacity for over 1400 crank horsepower.\n\nKey features include ball-bearing turbochargers, removal of stock turbo-fold restrictions, Weistec M157 Turbo Intake Tubes, CNC billet aluminum compressor wheels, improved airflow, and an aggressive exhaust note, all contributing to greatly increased HP and torque capabilities. Additional required items for peak performance include a high-flow downpipe and exhaust, racing spark plugs, the Weistec WMI\/ASV, and a Weistec W.4 ECU Tune. Please note that these turbochargers are made to order, with orders typically shipping within 2-4 weeks. It is important to confirm tune availability for your specific application by contacting tuning@weistec.com. Furthermore, this item is NOT LEGAL FOR SALE OR USE ON POLLUTION CONTROLLED MOTOR VEHICLES. The W.4 Turbo Upgrade is compatible with the following vehicles: 2016-2019 Mercedes-Benz GLE63 AMG Base (W166) and 2017-2019 Mercedes-Benz GLE63 AMG Coupe (C292), all equipped with the Twin Turbo 5.5L V8 (M157) engine.","brand":"Weistec","offers":[{"title":"Default Title","offer_id":52866625831224,"sku":"01-157-01864-3","price":11699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687410029.jpg?v=1787909387","url":"https:\/\/store.motormia.co\/products\/w-4-turbo-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
