The Tracy Lewis Clean Side Separator mounts directly in place of your factory oil fill cap and tackles the problem at the source.\u003c\/p\u003e\n\u003cp\u003eAs air moves in and out of the crankcase, the internal filter media captures oil vapor before it ever reaches the intake — then lets it drain right back down into the crankcase where it belongs. Your engine breathes freely, your MAF sees 100% clean, metered air, and your intake tract stays exactly where it should: clean.\u003c\/p\u003e\n\u003ch2\u003eWhat Sets It Apart\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAll-billet construction\u003c\/strong\u003e — Machined aluminum body and billet barb fitting, zero plastic anywhere on the unit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversized vents\u003c\/strong\u003e — Larger vent openings than competing designs mean better crankcase airflow, not a bottleneck\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% MAF-safe\u003c\/strong\u003e — Every cubic inch of air stays properly metered; no signal contamination, no check-engine headaches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil fill cap replacement\u003c\/strong\u003e — Installs without permanent modifications; drop it in and you're done\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSignature Series matched\u003c\/strong\u003e — Designed to pair directly with Tracy Lewis Signature Series Catch Cans for a complete, cohesive system\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRX-level performance\u003c\/strong\u003e — Internally identical to the legendary RX Clean Side Separator, badged to match the Tracy Lewis Signature Series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf clean crankcase ventilation and intake protection matter to you, this is simply the best drop-in upgrade you can bolt on today.\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003eWhat does the Tracy Lewis Clean Side Separator do?\u003c\/h3\u003e\n\u003cp\u003eIt replaces the factory oil fill cap and uses internal filter media to capture oil vapor as air moves in and out of the crankcase, helping keep that vapor from reaching the intake.\u003c\/p\u003e\n\u003ch3\u003eHow does it help protect MAF readings?\u003c\/h3\u003e\n\u003cp\u003eBy capturing oil vapor before it reaches the intake tract, it helps the MAF see clean, properly metered air and helps prevent signal contamination from oil vapor buildup.\u003c\/p\u003e\n\u003ch3\u003eHow does the Tracy Lewis Clean Side Separator install?\u003c\/h3\u003e\n\u003cp\u003eIt mounts directly in place of the factory oil fill cap and installs without permanent modifications.\u003c\/p\u003e\n\u003ch3\u003eWhat is it made from?\u003c\/h3\u003e\n\u003cp\u003eIt features all-billet construction, including a machined aluminum body and billet barb fitting, with zero plastic anywhere on the unit.\u003c\/p\u003e\n\u003ch3\u003eWhat catch can system is it designed to match?\u003c\/h3\u003e\n\u003cp\u003eIt is designed to pair directly with Tracy Lewis Signature Series Catch Cans and is badged to match the Tracy Lewis Signature Series.\u003c\/p\u003e","brand":"Tracy Lewis Performance","offers":[{"title":"Default Title","offer_id":67666272485436,"sku":"TLP-CSS-01","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5934\/4956\/files\/ChatGPTImageJun8_2026at07_58_18PM.png?v=1791999315","url":"https:\/\/rpm-racing.com\/products\/tracy-lewis-clean-side-separator","provider":"Racing Precision Motorsports","version":"1.0","type":"link"}
