The factory cooler struggles to cool the charged air resulting in excessive intake air temperature due to its small size. This struggle results in ECU protecting the engine by pulling power during a single quarter mile pass, lap around a track, or even during a spirited drive. Simply bolting on the APR System relieves this issue, resulting in an instant boost in power and consistency. The APR system has no trouble remaining consistent thanks to its ability to resist power-robbing heatsoak!\nFeatures:\n\n194% larger than the factory intercooler\n5,500cm³ vs the undersized 1,870cm³ factory unit\nDramatically lowers intake air temperature\nConsistently more horsepower and torque\nFlows more than stock at every measured pressure differential\nCFD optimized cast aluminum end tanks\nProprietary aluminum cooling core\nCNC machined and tig welded construction\nApplication specific coolant hoses\nApplication specific ez-flow charge air hoses\nCNC bent and laser cut brackets\nDoes not negatively impact emissions\nDoes not require tuning\nInstructions and support included\n\n \nInstall Instructions: tl100171_rs5_intercooler_web.pdf (goapr.com)","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_001.jpg?v=1701448406","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_002.jpg?v=1701448410","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_003.jpg?v=1701448411","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_004.jpg?v=1701448413","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_005.jpg?v=1701448409","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_006.jpg?v=1701448407","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_007.jpg?v=1701448405","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_008.jpg?v=1701448409","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_009.jpg?v=1701448412","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_016.jpg?v=1701448411","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_017.jpg?v=1701448413","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_018.jpg?v=1701448407","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_020.jpg?v=1701448408","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_021.jpg?v=1701448412","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_024.jpg?v=1701448409","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_025.jpg?v=1701448410","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_026.jpg?v=1701448408","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_027.jpg?v=1701448406","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_028.jpg?v=1701448406","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/ic100028_029.jpg?v=1701448408"],"price":2199.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.937Z"},"share_url":"https://firestarter.network/l/lst_2X6EJGEx","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
