{"product_id":"hyper-one-h1-exhaust-camshaft","title":"Hyper One (H1) Exhaust Camshaft","description":"The Toda Hyper One (H1) camshaft is a specialized racing component for K20A engines, designed to maximize midrange performance between 4000 and 6000 RPM. Developed with Time Attack events in mind, where low-end power is secondary to corner-exit acceleration, the Hyper One camshaft features redesigned Pre and Sec cam lobes. This optimization contributes to significant gains in the torque band and power curve in the mid-to-upper RPM range, especially when utilized with Racing VTEC.\n\nThis exhaust camshaft (Part No. 14121-K20-11H) has specific lobe profiles with angles and lift: H1: 267(11.5) 95° \/ 292(12.0) 102.5°. It is intended for use in a set with the intake camshaft.\n\nInstallation of the Hyper One camshaft requires several prerequisites. Standard valve springs cannot be used; the TODA Up Rated Valve Spring is required. It is crucial to confirm adequate valve-to-piston clearance, valve-to-valve clearance, and cam lob-to-follower clearance during operation. Furthermore, this product is recommended for use in conjunction with the TODA Sports Injection KIT, specifically individual throttle bodies, as a single throttle body system may struggle with the unstable airflow at idle. For optimal results, VTEC engagement is recommended at 5850 rpm and disengagement at 5600 rpm.","brand":"Toda","offers":[{"title":"Default Title","offer_id":52664000414008,"sku":"14121-K20-11H","price":1400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687729376.jpg?v=1784331685","url":"https:\/\/store.motormia.co\/products\/hyper-one-h1-exhaust-camshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
