These springs are designed to replace broken or worn-out springs used on many manifold-to-engine pipe connections on late model cars.

This replacement kit contains 2 each of manifold bolts and ground, tempered springs that meet or exceed OE specifications. Locking nuts are also provided on some application. These fasteners are essential to insure a quiet, leak-free connection at the manifold, while they eliminate vibrations and rattles throughout the system.
