The Tomei Strengthened Timing Belt is an ultra-durable, high-performance timing belt engineered specifically for turbocharged EJ20 and EJ25 Subaru engines. Utilizing premium grade materials with enhanced resistance to heat, stretch, and engine fluids, this belt significantly increases operational longevity compared to traditional OEM counterparts. The belt's construction features teeth made from a specially formulated fiber-infused rubber compound and a wear-resistant, low-friction cover fabric, contributing to quieter operation. Strong glass fiber cords of high tensile strength are integrated to reinforce the belt, minimizing stretch even under demanding loads. A low-friction, crack-resistant blue top layer further extends the belt's lifespan while maintaining minimal operating noise. Precision manufacturing ensures this belt maintains your EJ20/EJ25 engine's timing in sync, delivering a consistent level of high performance. It serves as a direct replacement with factory-correct tooth profile and timing mark alignment for a straightforward installation. Replacing a worn or stretched timing belt is crucial for engine health and performance. Applications include Subaru EJ20/EJ25 Turbo engines, specifically fitting models such as the 2002-2011 Subaru Impreza, 2012-2014 Subaru WRX, 2004-2007 STi, 2008-2014 WRX, 2008-2014 STi, 2015-2021 STi, 2004-2008 Forester XT, and 2009-2013 Forester XT.
