The cowl delete modification is a popular weight reduction and engine bay cooling upgrade in the BMW E-Series performance community — removing the windshield cowl cover and HVAC filtration housing reduces vehicle weight by approximately 10 pounds, improves engine bay cooling, makes engine bay servicing easier, and allows the driver to hear the engine more clearly. However, deleting the factory cowl removes the dust and debris filtration that keeps contaminants out of the cabin ventilation system. This simplified cowl filter set restores that critical filtration function while preserving the benefits of cowl deletion — keeping dust, leaves, debris, and other contaminants out of the cabin air handler without reinstalling the heavy and bulky factory cowl housing.\n\u003c\/p\u003e\n\n\u003ch6\u003eFeatures:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCowl delete compatibility – designed to replace the factory HVAC filter housing function after cowl deletion modification\u003c\/li\u003e\n\u003cli\u003eRestores dust and debris filtration – prevents contaminants from entering the cabin ventilation system after the factory cowl is removed\u003c\/li\u003e\n\u003cli\u003eReduced vehicle weight – the cowl delete modification reduces vehicle weight by approximately 10 lbs (4.5 kg) compared to factory configuration\u003c\/li\u003e\n\u003cli\u003eImproved engine bay cooling – the cowl delete enables better engine bay airflow for spirited driving and track use\u003c\/li\u003e\n\u003cli\u003eEnhanced engine sound – removing the cowl allows the engine intake and operational sounds to be more audible from the cabin\u003c\/li\u003e\n\u003cli\u003eEasier maintenance access – cowl deletion exposes the DME box, spark plugs, valve cover, and other engine bay service points for faster service\u003c\/li\u003e\n\u003cli\u003eEasy cleaning and reuse – simply rinse with water, allow to dry, and reinstall (do not oil)\u003c\/li\u003e\n\u003cli\u003eBlack color blends seamlessly into the engine bay environment\u003c\/li\u003e\n\u003cli\u003eDirect retrofit installation – mounts using factory hardware locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eSpecifications:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eCondition: 100% Brand New\u003c\/li\u003e\n\u003cli\u003eType: Cowl Delete Replacement Filter Set (2-Piece)\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eItem Weight: 0.28 kg\u003c\/li\u003e\n\u003cli\u003eQuantity: 2 cowl filters per pack\u003c\/li\u003e\n\u003cli\u003eReusable: Yes (rinse-and-reinstall)\u003c\/li\u003e\n\u003cli\u003ePosition: Engine Bay \/ Cowl Area (post-cowl-delete)\u003c\/li\u003e\n\u003cli\u003ePurpose: Cowl Delete HVAC Filtration \/ Engine Bay Optimization\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eFitment:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW 1 Series E81 \/ E82 \/ E87 \/ E88 (2005 – 2013):\u003c\/strong\u003e Including 116i, 116d, 118i, 118d, 120i, 120d, 123d, 125i, 128i, 130i, 135i, 1M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW 3 Series E90 \/ E91 \/ E92 \/ E93 (2005 – 2013):\u003c\/strong\u003e Including 316i, 316d, 318i, 318d, 320i, 320d, 323i, 325i, 325d, 328i, 330i, 330d, 335i, 335d, M3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW X1 E84 (2010 – 2015):\u003c\/strong\u003e Including 16i, 16d, 18i, 18d, 20i, 20d, 25i, 25d, 28i, 28ix, 35ix\u003c\/li\u003e\n\u003cli\u003eDesigned for vehicles with cowl delete modification already performed – not intended for factory configuration vehicles\u003c\/li\u003e\n\u003cli\u003eCompatible with all engine variants and trim levels within the listed chassis range, including M3 and 1M variants\u003c\/li\u003e\n\u003cli\u003eConfirm vehicle model, chassis code, and cowl delete modification status before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eContents:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e2x Cowl Delete Replacement Filters\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eImportant Note:\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting hardware NOT included:\u003c\/strong\u003e Source mounting hardware separately – use factory part number 07147146539 or equivalent bolts of similar size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCowl delete prerequisite:\u003c\/strong\u003e This filter set is designed to be installed AFTER performing the cowl delete modification (removal of windshield cowl cover and factory HVAC filter housing).
