Review HOWARDS RACING COMPONENTS Stock Dia. Performance Single 1.445 Valve Spring

The Howard's Racing 98412 Performance Single 1.445 Valve Spring is an essential upgrade for racing and high-performance applications on 1.8L and 2.0L Subaru and Toyota engines. Designed with a larger diameter and increased spring pressure, this valve spring offers superior performance and reliability compared to stock components.

The 1.445-inch diameter of this valve spring is significantly larger than the stock springs, allowing for increased valve lift and improved engine breathing. The larger diameter also enhances the spring's ability to maintain its shape under high RPM and boosted conditions, reducing the risk of valve bounce and ensuring consistent combustion.

The Performance Single 1.445 Valve Spring is made from high-quality materials, ensuring durability and reliability. The spring steel used is specially selected for its strength and ability to withstand the rigors of racing and high-performance driving. The springs are also shot-peened to create a compressive stress on the surface of the spring, increasing its fatigue strength and reducing the risk of fatigue failure.

This valve spring also features a closed-end design, which eliminates the need for retainer springs and reduces the overall weight of the valvetrain. The closed-end design also helps to reduce valve float, providing more consistent valve control and improving engine performance.

The Howard's Racing 98412 Performance Single 1.445 Valve Spring is a direct replacement for stock components and is easy to install. It is recommended for use in racing and high-performance applications where increased valve lift, improved engine breathing, and enhanced reliability are essential. This valve spring is also suitable for use with aftermarket camshafts and performance intake systems.

In summary, the Howard's Racing 98412 Performance Single 1.445 Valve Spring is a high-performance upgrade for 1.8L and 2.0L Subaru and Toyota engines. Its larger diameter, increased spring pressure, and high-quality materials make it an ideal choice for racing and high-performance driving, while its closed-end design and easy installation make it a practical and effective modification for any enthusiast looking to maximize the potential of their engine.
