Each bar is heat-treated and shot-peened

Since rail pressures typically run in the area of approximately 27

4lbs on each corner over the factory 27

During testing we found this to make a significant decrease to airflow and inlet air temperatures (IAT’s)

NGK - Laser Iridium - ILFER7B8EG TT232 InternallyNGK Laser Iridium spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts.
