Supertech Block Guard for Nissan 350 VQ35DET (Left & Right Side)

This is the Supertech block guard kit, designed specifically for the Nissan 350Z with the VQ35DET engine. If you're planning on pushing your VQ35DET beyond its stock power levels, especially with forced induction, a block guard is a smart addition to help reinforce the cylinder walls. It works by tying the cylinder sleeves together, preventing them from flexing or distorting under increased boost pressure.

This kit includes both the left and right side block guards, made from solid aluminum. This material choice helps manage heat and adds rigidity without excessive weight. The design aims to provide a strong, well-built reinforcement for the engine block's critical areas. Proper installation is key to ensuring it functions as intended, supporting your engine's increased demands.
