The press-in swivel architecture mirrors Radium's other Nissan valve cover fittings, sealing in the OEM bore while the AN end rotates freely to aim the catch can lines. Builders balancing the two vent ports can also look to Radium's double-ended 16mm SAE quick connect version of the RB26 fitting in the same family. Pairs naturally with Radium's 10AN and 12AN catch can plumbing on R32 through R34 GT-R builds.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x 12AN male press-fit swivel fitting (20-0809)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNissan RB26DETT valve covers, intake and exhaust (1989-2002 Skyline GT-R R32\/R33\/R34)\u003c\/li\u003e\n\u003cli\u003eOrder 2 to replace both OEM fittings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":43672697471043,"sku":"20-0809","price":56.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0809-28753921867846_bd9e6633-7b72-4f63-9374-3f92cf94e273.jpg?v=1786717179","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-engineering-12an-male-press-fit-rb26dett-intake-and-exhaust-1989-2002-nissan-skyline-gt-r-20-0809","provider":"Tuned by Shawn","version":"1.0","type":"link"}
