Description

The AEM 23-831BK Tru-Time Adjustable Cam Gear is engineered for the Mitsubishi 4G63 engine, specifically fitting Lancer Evolution IV through IX models from 1996 to 2006. This direct-fit component, featuring a durable black anodized finish and a precise 5-bolt pattern, allows tuners to independently adjust intake and exhaust camshaft timing. By enabling fine-tuning of cam profiles, this adjustable gear can help increase horsepower and torque without the need to swap camshafts. It is particularly beneficial for engines that have undergone modifications such as cylinder head milling. Installation typically requires no modifications to the vehicle. This AEM Tru-Time cam gear is an essential item for those looking to optimize engine performance on their modified Mitsubishi Lancer Evolution. Its adjustable nature provides a critical tuning capability for achieving peak engine efficiency and power output.
