Our inline fuel filter is a simple plug and play and takes about 30 minutes to fully install.  The NRW Inline fuel filter uses industry leading replacement fuel filters from Aeromotive.  Gasoline paper filter part #12601 and the E85 Micro Glass filter part #12650.  This allows for the ultimate filtration and allows the customer to easily find replacement filters when needed.  Our hose is made from PTFE and allows the user to run E85 safely.  Tested on both Supercharged and NA applications our filter has exceeded our expectations.  The NRW Design filter housing has been designed to relocate your low-pressure sensor found on your stock fuel rail and relocates it after the filter.  By doing so, this allows the DME to control fuel pressure if the housing is sensing low pressure due to either a contaminated filter or issues in the fuel system. NRW Design has really put a lot of thought behind this design and is proud to be able to offer another layer of safety and protection to our beloved E9X M3s.  \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.nrw-design.com\/blogs\/news\" title=\"E9X M3 Blog\"\u003e See our BLOG for more information...\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOur filter kit includes the following:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1:\u003c\/strong\u003e 2 Part Design Filter Housing \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2:\u003c\/strong\u003e Viton O-Ring\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3:\u003c\/strong\u003e Aeromotive Fuel Filter \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e4:\u003c\/strong\u003e Quick Connect PTFE Fuel Line \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e5:\u003c\/strong\u003e Bracket Nut \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e6:\u003c\/strong\u003e Low Pressure Fuel Sensor Plug \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e7:\u003c\/strong\u003e Fuel Filter Housing \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.tdott.me\/2024\/01\/nrw-inline-fuel-filter-install.html?m=1\"\u003e\u003cstrong\u003eH\u003cspan style=\"font-size: 0.875rem;\"\u003eOW TO INSTALL FUEL FILTER\u003c\/span\u003e\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003ePLEASE note - the hose in picture is the old style hose with PTFE.  We have moved to the radium EFI hose as it’s far superior to PTFE.  We will be updating pictures shortly to represent the new style hose and connectors. \u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"NRW-Design","offers":[{"title":"Gasoline Paper Filter","offer_id":47489459585343,"sku":"S65PFF","price":309.99,"currency_code":"USD","in_stock":true},{"title":"E85 Micro Glass Filter","offer_id":47489459618111,"sku":"S65EFF","price":329.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/0809\/6319\/files\/74969F47-AAC8-4353-8937-D85683BC1743.jpg?v=1773341157"},{"product_id":"nrw","title":"NRW Design Viton Florine Rubber Oil Cap Gasket O-Ring","description":"\u003cspan data-mce-fragment=\"1\"\u003eWe set out to find a possible simple fix to the leaking oil cap found on many E9x M3s.

Many people attempt to double up O rings, apply gasket sealant, or spend money on a new oil cap. Even though the factory oil caps are inexpensive, we have seen brand new oil caps that still are weak and leak. Our solution was to create a gasket O-Ring that was a single piece, replaces the factory OEM gasket O-Ring, provides thicker material to mate with the surface of the valve cover, and do so with cost in mind. $10.00 USD.

valve cover.\u003cbr\u003eThroughout development, we produced multiple design revisions, extensive prototypes, and numerous test units to ensure every aspect of the final product met our standards before release.\u003cbr\u003eEngineered to Eliminate OEM Weaknesses\u003cbr\u003eOne of our primary objectives was eliminating the factory PCV system—a well-known failure point that has affected BMW turbocharged engines since the S55 platform.\u003cbr\u003eOur billet valve cover is designed to operate with an external catch can system, providing a more robust and reliable crankcase ventilation solution for both street and high-performance applications.\u003cbr\u003eLeveraging what we learned while developing our S58 valve covers, we incorporated three -12 ORB\/AN ports to efficiently evacuate excessive crankcase pressure under extreme operating conditions. Proper crankcase evacuation becomes increasingly important on high-boost applications and can help reduce valve train instability, including the cam timing movement commonly referred to as “VANOS walk,” often experienced at boost pressures exceeding 45 psi.\u003cbr\u003eEach valve cover includes:\u003cbr\u003e ● (2) -12AN swivel fittings\u003cbr\u003e ● (1) -12 ORB\/AN block-off fitting\u003cbr\u003e ● (1) 1\/8” NPT plug\u003cbr\u003e ● OEM BMW valve cover gasket\u003cbr\u003e ● OEM BMW HPFP gasket\u003cbr\u003eThe third port also provides the flexibility to expand your crankcase ventilation system in the future should your application require additional evacuation capacity.\u003cbr\u003eTrue Single-Piece Billet Construction\u003cbr\u003eOur valve cover is CNC machined from a single block of 6061-T6 aluminum for one simple reason—reliability.\u003cbr\u003eA true single-piece design minimizes potential leak paths while maximizing structural rigidity. Although multi-piece valve covers can simplify cylinder head re-torque procedures, we believe the added sealing surfaces introduce unnecessary opportunities for leaks.\u003cbr\u003eIn our experience, the minimal time savings simply do not outweigh the long-term reliability benefits of a one-piece design. Furthermore, vehicles requiring routine head re-torquing are typically dedicated race cars that often do not retain the factory cowl, making this feature unnecessary for the vast majority of customers.\u003cbr\u003eInternal PCV Port Elimination\u003cbr\u003eUnlike many aftermarket solutions, our valve cover internally blocks the factory intake ports used by the OEM PCV system.\u003cbr\u003eThis eliminates the need for external plugs after removing the factory PCV assembly while preventing oil vapor from re-entering the intake manifold. The result is a cleaner intake tract and reduced carbon buildup on the intake valves over time.\u003cbr\u003eAttention to Detail\u003cbr\u003eWe also incorporated machined ignition coil dust seals into every valve cover—a detail many competing designs overlook.\u003cbr\u003eWithout proper sealing, dust, oil, and debris can accumulate around the spark plug wells and potentially enter the cylinder head during routine maintenance. While machining these features adds manufacturing time and cost, we believe attention to detail is what separates a premium product from the rest.\u003cbr\u003eOEM Serviceability\u003cbr\u003eLong-term serviceability was another priority throughout development.\u003cbr\u003eOur valve cover exclusively utilizes OEM BMW gaskets, eliminating the need for proprietary seals or custom replacement components. Owners can source replacement gaskets anywhere genuine BMW parts are available.\u003cbr\u003eAdditional Features\u003cbr\u003e ● Internal baffling to improve oil control during high-RPM and high-load operation\u003cbr\u003e ● Integrated 1\/8” NPT port for crankcase pressure sensors, including RIFE sensors\u003cbr\u003e ● Compatible with BM3, MHD, and standalone ECU systems for crankcase pressure monitoring and engine fail-safe strategies\u003cbr\u003eActive crankcase pressure monitoring provides valuable engine health data and can be used to trigger safety strategies in the event of excessive crankcase pressure associated with head lift or head gasket failure.\u003cbr\u003eBuilt Without Compromise\u003cbr\u003eEvery NRW Design B58 Gen 2 Billet Valve Cover is proudly designed, engineered, and manufactured in the USA using domestically sourced 6061-T6 aluminum.\u003cbr\u003eWe believe this is the ultimate long-term upgrade for the commonly failing OEM B58 plastic valve cover—combining premium materials, thoughtful engineering, and uncompromising manufacturing standards into one complete solution.\u003cbr\u003e\u003cbr\u003eThank you for your continued support.\u003cbr\u003eNRW Design\u003c\/h3\u003e","brand":"NRW-Design","offers":[{"title":"Default Title","offer_id":52950718054719,"sku":null,"price":3199.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/0809\/6319\/files\/0EDD52A1-16AA-4C97-ACC5-0110D72777BA.jpg?v=1785081300"},{"product_id":"nrw-design-billet-oil-cap","title":"NRW Design Billet Oil Cap","description":"\u003cdiv class=\"gs\"\u003e\n\u003cdiv class=\"\"\u003e\n\u003cdiv class=\"ii gt adO\" id=\":ob\"\u003e\n\u003cdiv class=\"a3s aiL\" id=\":oa\"\u003e\n\u003cdiv id=\"avWBGd-34\"\u003e\n\u003cdiv dir=\"auto\"\u003e\n\u003cp\u003e\u003cspan\u003eFor nearly two decades, BMW enthusiasts have dealt with the same frustrating issue—a factory oil cap design that has been prone to seeping and leaving oil residue across the valve cover.
