High thermal loads combined with road vibrations lead to micro-fractures, boost leaks, and internal core contamination.

Measuring 37-1\/8 inches in height between tanks, 21-5\/8 inches in core width, and 2 inches in core depth, it maximizes heat dissipation surface area without creating excessive intake air restriction. Factory-positioned 4-inch inlet and outlet beaded hose necks ensure high-pressure seal retention under constant boost expansion.
