Tomei TB103A-SB01A Belt Guide for Subaru
Since 1968, Tomei has been at the forefront of automotive performance, crafting parts that stand up to the rigorous demands of racing. With decades of expertise, Tomei knows that every detail counts, especially when it comes to engine performance. The Tomei TB103A-SB01A Belt Guide is a perfect example of this commitment to quality and precision, designed specifically for Subaru models equipped with the EJ20 and EJ25 engines.
Why Upgrade to the Tomei Belt Guide?
If you're a proud owner of a Subaru WRX or WRX STI, you know that the factory timing belt guide can leave a lot to be desired. Made from flimsy sheet metal, the stock guide often fails to keep the timing belt secure, especially under the extreme conditions that high-performance driving demands. This can lead to catastrophic engine failure if the belt slips. The Tomei TB103A-SB01A is engineered to eliminate these risks.
Key Features
- Robust Construction: Crafted from high-quality aluminum, this belt guide is built to withstand the heat and strain of high horsepower applications.
- Enhanced Reliability: The extended length of the Tomei guide applies increased tension to the timing belt, reducing the risk of belt whip during sudden torque changes.
- Precision Engineering: Tomei's attention to detail ensures that all components are machined to exact tolerances, improving airflow and fitment.
- Stylish Anodized Finish: Not only does it perform well, but the anodized surface also adds a sleek touch to your engine bay.
Specifications
- Compatible Models: Subaru WRX EJ20 (2002-2005), Subaru WRX STI EJ20 (2001-2007), Subaru WRX EJ25 (2002-2014), Subaru WRX STI EJ25 (2004-2007)
