Ceramic/Moly Piston Coating
Coating the piston reduces friction and wear, reduces part operating temperature, can increase horse power and torque, reduce or eliminate detonation, and allow tighter piston to wall clearances for a better ring seal.

ARP VQ37VHR Main Stud Kit - Nissan 370z/Infiniti G37
The ARP VQ37 Main Stud Kit for the Nissan 350z/Infiniti G37 is a must have for anyone looking to rebuild their VQ37VHR motor.

ARP recommends the use of main studs over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don’t “twist” into the block. All clamping forces are on one axis. By the same token, there is less force exerted on the block threads, which contributes to improved block life (very critical on aluminum blocks). Finally, there are factors of easier engine assembly and proper alignment of caps every time.
