Radium's FPD-R architecture serves the damping across the fuel range including E85, and the kit's Supra-specific fitment lands it in the JZA80's plumbing without fabrication. Install per Radium's instructions, and the datalogs smooth out where the waves used to live.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Radium fuel pulse damper with Supra-specific fitment hardware (20-0389)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1993-1998 Toyota Supra MK4 (JZA80, 2JZ-GTE)\u003c\/li\u003e\n\u003cli\u003eCompanion to Radium 2JZ rail and fuel system installations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672708317251,"sku":"20-0389","price":208.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0389-29454188740678_5ad4f184-331c-448a-84d4-96f81ba86a6c.jpg?v=1786717390","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-fuel-pulse-damper-kit-1993-1998-toyota-supra-20-0389","provider":"Tuned by Shawn","version":"1.0","type":"link"}
