{"product_id":"k24-intake-manifold-adapter-1","title":"K24 Intake Manifold Adapter","description":"The K-Tuned K24 Intake Manifold Adapter offers a straightforward solution for installing K20-style intake manifolds onto K24 cylinder heads. Engineered to be compatible with all K24 engines, including the specific K24Z-Series (R40) heads, this adapter ensures broad application. It also provides a pathway to fit K20 manifolds or modified RBC manifolds onto 9th generation Civic Si vehicles by addressing the slight differences in the water bypass system, eliminating the need for an additional intake manifold adapter.\n\nA key benefit of this adapter is its ability to reduce intake air temperatures. By isolating the intake manifold from the engine's coolant, it prevents heat soak. This temperature reduction directly impacts air density, as noted by Hondata's findings that intake air density decreases by 1% for every 5°F rise in temperature. Utilizing this adapter can help recapture performance that would otherwise be lost due to elevated intake air temperatures.\n\nThe adapter is equipped with a 1\/8 NPT port, providing a convenient location for installing a coolant temperature sensor, a common requirement in many engine swap setups. Installation can be performed using the included spring-loaded tab for a secure seal with gasket maker, or by tapping the cylinder head. For the tapping method, the required tools include a 6.5mm drill bit to finish the adapter's blind hole, a 5mm drill bit for the cylinder head, and an M6x1.0 tap. Detailed instructions are available via a provided link.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":52686536343864,"sku":"KTDINTK24","price":104.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/659229011.webp?v=1784874678","url":"https:\/\/store.motormia.co\/products\/k24-intake-manifold-adapter-1","provider":"MOTORMIA","version":"1.0","type":"link"}
