Tall - Red\u003c\/h4\u003e\n\u003cp\u003eThe Spectre HPR9891 is a large-format conical air filter designed for demanding high-performance intake applications. With a 6-inch flange ID, 7.719-inch base OD, and an 8.5-inch overall height, this is one of the tallest and highest-flowing conical filters in the Spectre HPR lineup. The extra height and swept cone geometry dramatically increase filtration surface area, supporting higher airflow numbers for turbocharged, supercharged, or naturally aspirated high-displacement builds. Constructed with oiled cotton gauze media in a distinctive red finish, HPR9891 is washable, reusable, and ready for serious performance use.\u003c\/p\u003e\n\n\u003ch4\u003eFeatures and Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eExtra-tall 8.5-inch conical design for maximum filter surface area\u003c\/li\u003e\n\u003cli\u003e6-inch flange ID accommodates large-diameter intake tubing\u003c\/li\u003e\n\u003cli\u003e7.719-inch base OD for broad, stable base contact\u003c\/li\u003e\n\u003cli\u003eOiled cotton gauze media provides filtration with high airflow\u003c\/li\u003e\n\u003cli\u003eRed finish with anodized caps for premium underhood appearance\u003c\/li\u003e\n\u003cli\u003eWashable and reusable to reduce long-term maintenance cost\u003c\/li\u003e\n\u003cli\u003eRubber seal flange ensures an airtight connection to intake tube\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eHPR9891\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSpectre Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter Shape\u003c\/td\u003e\n\u003ctd\u003eConical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlange ID\u003c\/td\u003e\n\u003ctd\u003e6 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBase OD\u003c\/td\u003e\n\u003ctd\u003e7.719 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e8.5 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter Media\u003c\/td\u003e\n\u003ctd\u003eOiled Cotton Gauze\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eRed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReusable\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eLimited lifetime\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Spectre HPR9891 Conical Air Filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the flange size on the HPR9891?\u003c\/strong\u003e\u003cbr\u003eThe HPR9891 uses a 6-inch flange ID, making it compatible with 6-inch OD intake tubes and adapters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the HPR9891 compare to the HPR9892?\u003c\/strong\u003e\u003cbr\u003eBoth share the same 6-inch flange and similar base OD, but the HPR9891 is taller at 8.5 inches versus 7 inches, offering more filter media surface area and higher peak airflow potential.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the HPR9891 reusable?\u003c\/strong\u003e\u003cbr\u003eYes.
