{"product_id":"5th-injector-kit","title":"5th Injector Kit","description":"When the stock mechanical fuel pump and injectors reach their limit, this kit diverts fuel and sprays it into the intake manifold. The kit includes an adjustable controller that is mounted inside the vehicle. This controller allows for precise setting of the MAF frequency at which the fifth injector starts to spray fuel, beginning at a low duty cycle to prevent abrupt changes in the air-fuel ratio. A high-frequency setting determines when the injector reaches its maximum duty cycle.\n\nThe injector itself mounts directly to the intake manifold using an existing hole, eliminating the need to remove the manifold from the engine. Installation is straightforward; the most time-consuming part is typically routing the wiring into the cabin and mounting the controller. The process involves unbolting the factory EVAP solenoid, mounting the ZZP 5th injector kit, re-installing the EVAP solenoid on the supplied bracket, and connecting four wires.\n\nZZPerformance recommends tuning this 5th injector kit in conjunction with ECM adjustments through HP Tuners. This allows for decreasing MAF values in the ECM to compensate for the additional fuel supplied by the fifth injector. The MAF-based design is intended to be easier to tune compared to previous MAP-based systems. For detailed installation guidance, refer to the provided digital install instructions.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52867023733048,"sku":"ZZ-LNF5INJ","price":449.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687424614.jpg?v=1787910096","url":"https:\/\/store.motormia.co\/products\/5th-injector-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
