{"product_id":"ff640-640cc-fuel-injector-kit","title":"FF640 640cc Fuel Injector Kit","description":"The FlowForce FF640 is a flagship plug-and-play injector kit engineered for 1990-2005 Mazda Miatas (NA\/NB). These injectors are built using new OEM EV14 components, meticulously matched into sets that flow within a tight +\/-1% tolerance at both idle and wide-open throttle. This precision is crucial for maintaining drivability, especially on a 4-cylinder engine.\n\nThe FF640 injectors deliver 640cc of fuel flow in NA Miatas and 725cc in NB Miatas. This provides ample headroom for serious street and track builds, supporting approximately 300-350 horsepower on turbocharged applications.\n\nInstallation and configuration guidelines should be consulted prior to installation. While the stock fuel pump may suffice for some NA\/NB builds with FF640 injectors or smaller, pairing with a DW200 fuel pump is recommended for higher-flow applications or turbo builds. The DW200 fuel pump can be added for an additional cost and uses stock wiring without requiring tune changes.","brand":"Flowforce","offers":[{"title":"Default Title","offer_id":52688380821816,"sku":"FF640-DW200-90","price":329.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687899553.webp?v=1784889370","url":"https:\/\/store.motormia.co\/products\/ff640-640cc-fuel-injector-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
