While effective for emissions control, these gases also carry oil vapor, fuel, and moisture that can accumulate in the intake manifold over time. These contaminants contribute to carbon buildup on intake valves, reduce effective fuel octane, and increase the likelihood of detonation. The PRL Helix Air Oil Separator is designed to remove these contaminants before they are reintroduced into the intake system, helping maintain a cleaner intake path and more consistent engine operation without venting metered air or altering factory drivability.\u003c\/p\u003e\n\u003cp data-start=\"1054\" data-end=\"1619\"\u003eAt the core of the PRL AOS is a proprietary internal helix that creates controlled centrifugal motion within the canister. As blowby gases enter the system, heavier oil droplets, fuel, and moisture are forced outward toward the walls of the can, where they condense and collect at the bottom. The cleaned air is then routed back into the intake system, ensuring closed loop operation and preserving proper fueling behaviour. The system is fully serviceable and must be drained at regular intervals, with service frequency depending on climate and driving conditions.\u003c\/p\u003e\n\u003cp data-start=\"1621\" data-end=\"2175\"\u003eEach PRL Helix AOS is designed and produced in house using CNC machined 6061-T6 billet aluminium and finished with a durable hard anodized coating. The canister is available in both Black and Silver anodized finishes and is paired with a laser cut and CNC bent 304 stainless steel mounting bracket. Custom moulded reinforced rubber hoses, billet aluminium fittings, a billet check valve, and Viton O-rings are used throughout the system to ensure long term durability, chemical resistance, and a clean OEM style installation suitable for the FL5 engine bay.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(178, 0, 0);\"\u003e\u003cstrong\u003eTECH SPECS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eCNC machined 6061-T6 billet aluminum canister with hard anodized finish\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eAvailable in Black or Silver anodized options\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eProprietary internal helix separation design\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eCustom billet aluminum fittings and billet check valve\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eViton O-rings for superior durability and chemical resistance\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eNBR reinforced rubber hoses designed for engine bay environments\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003e304 stainless steel laser cut and CNC bent mounting bracket\u003c\/li\u003e\n\u003cli data-start=\"2198\" data-end=\"2712\"\u003eRetains closed loop operation and does not interfere with emissions equipment\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: rgb(178, 0, 0);\"\u003eWHAT'S IN THE BOX\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"2790\" data-end=\"2970\"\u003ePRL Helix Air Oil Separator canister\u003c\/li\u003e\n\u003cli data-start=\"2790\" data-end=\"2970\"\u003eStainless steel mounting bracket\u003c\/li\u003e\n\u003cli data-start=\"2790\" data-end=\"2970\"\u003eCustom molded hose set\u003c\/li\u003e\n\u003cli data-start=\"2790\" data-end=\"2970\"\u003eBillet fittings and check valve\u003c\/li\u003e\n\u003cli data-start=\"2790\" data-end=\"2970\"\u003eAll required clamps and installation hardware\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong style=\"color: rgb(178, 0, 0); font-size: 0.875rem;\"\u003eFITTING DETAILS\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eDream Automotive offers in-house fitting on all products at our workshop in Luton, Bedfordshire.\u003cstrong\u003e\u003cspan style=\"color: rgb(178, 0, 0);\"\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(178, 0, 0);\"\u003e\u003cstrong\u003eAVAILABILITY\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e2-3 Weeks\u003c\/p\u003e","brand":"PRL Motorsports LLC","offers":[{"title":"Silver","offer_id":56904558903679,"sku":"PRL-1052-1-SIL","price":299.74,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":56904558936447,"sku":"PRL-1052-1-BLK","price":299.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/0870\/files\/PRL_Air_Oil_Separator_FK7_5.webp?v=1770374587","url":"https:\/\/www.dream-automotive.com\/products\/prl-motorsport-helix-air-oil-separator-honda-civic-fk7-1-5t-k20c1-2016-2021","provider":"Dream Automotive","version":"1.0","type":"link"}
