The phenolic washers are a small detail that earns its place, since the BP's aluminum intake manifold conducts engine heat straight into anything bolted to it, and insulating the rail keeps fuel temperature more consistent on hot days and long sessions. This kit is the bare rail with mounting hardware, so plan your fittings up front. For plug-and-play factory hookups, Radium offers separate plumbing kits: the 1994-1997 version retains the OEM regulator and replaces the feed and return hoses, while the 1999-2005 version retains the OEM pulse damper and feed hose, noting that EGR-equipped cars need the EGR removed for damper clearance.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x Black anodized, laser etched fuel rail\u003c\/li\u003e\n\u003cli\u003eStainless steel mounting hardware\u003c\/li\u003e\n\u003cli\u003ePhenolic thermal insulating washers\u003c\/li\u003e\n\u003cli\u003ePlumbing and fittings sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1994-1997 Mazda Miata (1.8L BP)\u003c\/li\u003e\n\u003cli\u003e1999-2005 Mazda MX-5 Miata (1.8L BP)\u003c\/li\u003e\n\u003cli\u003e1994-1996 Eunos Roadster (1.8L BP)\u003c\/li\u003e\n\u003cli\u003eCompatible with most Mazda 1.8L DOHC BP engines and factory-size injectors\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672690753603,"sku":"20-0369","price":142.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0369-28367685320774_965c4751-6265-4c9a-b6d1-6fbb221b67d6.jpg?v=1786717069"},{"product_id":"radium-fuel-rail-plumbing-kit-1994-2005-mazda-miata-20-0422-20-0423","title":"Radium Fuel Rail Plumbing Kit | 1994-2005 Mazda Miata (20-0422\/20-0423)","description":"\u003cp\u003e\u003cstrong\u003eThe Radium Miata rail has the ports; this kit is the plug-and-play bridge back to your factory fuel lines.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA bare aftermarket rail leaves you sourcing fittings and hose to meet the OEM system.

One clearance note straight from Radium for the 99-05 kit: if the car is equipped with EGR, it must be removed for the OEM fuel pulse damper to fit. Both kits assume the Radium rail is already on the engine and the rest of the factory fuel system is stock; builds moving to aftermarket regulators or larger feed lines should skip this kit and plumb the rail's 8AN ORB ports directly with Radium adapter fittings instead.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e20-0422: 1x 8AN ORB to 5\/16\" barb fitting, 1x 8AN ORB to OEM FPR fitting, 1x 8AN ORB plug, Radium 5\/16\" fuel hose\u003c\/li\u003e\n\u003cli\u003e20-0423: adapters and hardware to retain the OEM pulse damper and feed hose on the Radium rail\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e20-0422: 1994-1997 Mazda Miata (1.8L BP) with the Radium 20-0369 fuel rail\u003c\/li\u003e\n\u003cli\u003e20-0423: 1999-2005 Mazda MX-5 Miata (1.8L BP) with the Radium 20-0369 fuel rail; EGR removal required for OEM damper fitment if equipped\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"1994-1997 Miata","offer_id":43672691572803,"sku":"20-0422","price":47.45,"currency_code":"USD","in_stock":true},{"title":"1998-2005 Miata","offer_id":43672691605571,"sku":"20-0423","price":56.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0422-1994-1997-miata-14642147885126_835fe389-7ab8-4e33-8edf-d2800d360307.jpg?v=1786717079"},{"product_id":"radium-engineering-catch-can-kit-1990-2005-mazda-miata-20-0336-fl","title":"Radium Engineering Catch Can Kit | 1990-2005 Mazda Miata (20-0336-FL)","description":"\u003cp\u003e\u003cstrong\u003eThirty years of spirited Miata miles push a lot of oil vapor toward one small intake.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eRadium Engineering Catch Can Kit for the 1990-2005 Mazda Miata\u003c\/strong\u003e intercepts it: a Radium Fluid Lock catch can with 2-step oil separation baffling plumbed into the crankcase ventilation of the NA and NB, keeping oil and sludge out of the intake tract that feeds everything from stock B6 commuters to boosted BP track builds.

The PCV hose sees metered vacuum at idle, steady cruise, and deceleration, drawing crankcase vapour, unspent fuel, and oil sludge into the manifold right after a hard run. The CCV line sits at atmospheric pressure at low load but flows hard out of the crankcase at wide open throttle, which is what coats the intake system. There is no fixed emptying interval; check the dipstick at three to four weeks and set your own schedule, noting PCV cans usually collect more than CCV cans.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBaffled Fluid Lock oil catch can, or two cans on the dual kit\u003c\/li\u003e\n\u003cli\u003eAnodized aluminum mounting bracket(s)\u003c\/li\u003e\n\u003cli\u003eSAE quick connect hose ends and fittings\u003c\/li\u003e\n\u003cli\u003e3\/8in PCV rubber hose, spring clamps, and cable zip-ties\u003c\/li\u003e\n\u003cli\u003eStainless mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1998-2005 Mazda MX-5 Miata NB, LHD and RHD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNOT compatible with the 1989-1997 MX-5 Miata NA or Eunos Roadster, because the flip-up headlight mechanism occupies the mounting space\u003c\/li\u003e\n\u003cli\u003eThe 20-1337-FL CCV add-on cannot be installed without the 20-1336-FL PCV kit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Dual Catch Can Kit, PCV and CCV (20-1338-FL)","offer_id":43700774109251,"sku":"20-1338-FL","price":446.45,"currency_code":"USD","in_stock":true},{"title":"PCV Catch Can Kit (20-1336-FL)","offer_id":43700774142019,"sku":"20-1336-FL","price":251.7,"currency_code":"USD","in_stock":true},{"title":"CCV Catch Can Add-On, requires 20-1336-FL (20-1337-FL)","offer_id":43700774174787,"sku":"20-1337-FL","price":204.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/20-1338-FL.jpg?v=1787354581"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/collections\/NB_MX-5_Miata.png?v=1623004496","url":"https:\/\/www.tunedbyshawn.com\/collections\/nb-mx-5-miata.oembed?page=2","provider":"Tuned by Shawn","version":"1.0","type":"link"}
