In the case of the factory post MAF hose, the quicker you can get it out of your bay, the better. We’ve now got you covered with The GrimmSpeed Post MAF Hose Kit that not only looks better, but fixes the flaws of its OE counter part.\u003c\/p\u003e\n\u003cp\u003eOur hose construction improves flow with 2 main features:\u003c\/p\u003e\n\u003cp\u003eThe first is the smooth inner surface, removing the pockets from the OE corrugated folds. These folds are necessary for the factory rubber design for flexibility during installation and structural integrity. The Grimmspeed hose is made with reinforced silicone, which is flexible, but has strong structural properties that enable us to have a hose that is very easy to install without worrying about collapsing under vacuum.\u003c\/p\u003e\n\u003cp\u003eThe second feature is a tapered center portion, making sure the inner diameter matches the OEM air box and turbo inlet. A mis-matched diameter creates steps, which will interrupt the air flow trajectories and create small vortexes in the post-MAF hose.\u003c\/p\u003e\n\u003cp\u003eNote: If you’ve got a 2015-17 STI with the factory sound generator tube and want to delete that piece, you can either purchase the 15-17 post MAF hose and GrimmSpeed Sound Plug Delete, or opt for the 18+ STI MAF hose.\u003c\/p\u003e\n\u003ch4\u003eQuick Specs\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ply Reinforced Silicone\u003c\/strong\u003e- Extremely durable avail. in red or black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM fitment\u003c\/strong\u003e- Easy install, no modification or tuning required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Flow\u003c\/strong\u003e- CAD optimized design\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHigh Quality Breeze Hose Clamps Included\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eGrimmSpeed Logo to Represent your Favorite Brand!\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cb\u003eFitment:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e15-17 Subaru WRX STI 2.5 Turbo EJ257\u003cbr\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003cstrong\u003e*NOTE: With factory integrated sound tube.*\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Grimmspeed","offers":[{"title":"Default Title","offer_id":40053474328662,"sku":"GRM125013","price":89.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0259\/7856\/8790\/products\/GrimmSpeed_PostMAFHose_05_1200px__45781.1607375039.jpg?v=1744210071","url":"https:\/\/nipponpower.com\/products\/grimmspeed-post-maf-hose-kit-black-subaru-15-17-sti-w-oem-sound-generator-tube-125013","provider":"Nippon Power","version":"1.0","type":"link"}
