{"product_id":"stealthbox-cold-air-intake-system-red","title":"StealthBox Cold Air Intake System, Red","description":"The GrimmSpeed StealthBox Cold Air Intake in red offers an enclosed system for the 2015-2018 Subaru WRX, designed to provide the performance of a cold air intake while mitigating engine bay heat soak. Unlike open element intakes, the StealthBox's enclosure seals the filter, drawing cooler air directly from the factory intake duct for more consistent air temperature management. The system utilizes a CNC mandrel-bent and CNC cut 6061 aluminum intake tube with 1\/8\" thickness for improved thermal control.\n\nInstallation is straightforward as a direct bolt-on, retaining the factory MAF sensor position and cold air inlet duct. This integration means no modifications to factory intake routing or MAF sensor relocation are necessary. The kit includes the GrimmSpeed StealthBox enclosure, an air filter, intake pipe, hardware, and installation instructions.\n\nWhile tuning is not strictly required for installation, it is recommended to optimize performance gains. The reusable synthetic dry filter ensures longevity and ease of maintenance. GrimmSpeed, based in Portland, Oregon, engineers its parts with a focus on real-world use and precise fitment for Subaru platforms.","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":52688614457656,"sku":"060067","price":415.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663179254.webp?v=1784891891","url":"https:\/\/store.motormia.co\/products\/stealthbox-cold-air-intake-system-red","provider":"MOTORMIA","version":"1.0","type":"link"}
