Trusted by leading engine builders worldwide, this direct replacement delivers 30% increased airflow without amplifying induction noise. The advanced multi-layer polyurethane foam construction allows air to flow freely around trapped dirt particles, maintaining performance as the filter loads. Independent MIRA testing confirms Pipercross foam captures more than twice the dust of competing filter types while preserving airflow efficiency. The triple-layer design features progressively finer filtration—coarse outer layers capture initial particles while the inner layer provides superior engine protection. When saturated, simply clean the filter with included solution and re-oil for extended service life. For high-performance applications demanding maximum flow capacity, the Pipercross PLUS Panel option offers 22.1% greater airflow through its specialized 2-layer construction combining 5mm 60PPI and 20mm 20PPI foam with enhanced dust-holding capability. Compatible with Discovery 3, Discovery 4, Range Rover L322 (2002-2009), and Range Rover Sport.\u003c\/p\u003e\u003cp\u003e=====\u003c\/p\u003e\u003cp\u003eFits Discovery 3 | Discovery 4 | Range Rover L322 2002 - 2009 | Range Rover Sport\u003c\/p\u003e\u003cp\u003e\u003cb\u003e\u003cem\u003eUsually ships in 1-2 weeks\u003c\/em\u003e\u003c\/b\u003e\u003c\/p\u003e","brand":"Terrafirma","offers":[{"title":"Default Title","offer_id":54077477650715,"sku":"TF391","price":91.46,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/9268\/8923\/files\/TF391_5fc9044b-082e-483e-ab54-46e444ff52b7.jpg?v=1790960347","url":"https:\/\/shop.rovalution.ca\/products\/terrafirma-foam-air-filter-1","provider":"Rovalution Automotive Proudly Canadian","version":"1.0","type":"link"}
