Holley Sniper EFI Stealth 4500 - Black

Supports Up To 1500 HP - 3.5 in. LCD Touchscreen - 8 x 100 lb./hr. Injectors

Featuring (8) 100 lb./hr. fuel injectors, the Stealth 4500 is a great option for any build looking to make between 800-1500 HP naturally aspirated or 1250 HP forced induction engines. This is a great pairing for dragster, pro street, and other aggressive applications with multiple input and output options for sensors, switches, and relays. Flowing 1440 CFM for larger cubic inch engines, the Dominator style main body four bolt air cleaner flange keeps increased amount of air moving. Included is a built in MAP sensor rated at 2.5 BAR and programmable launch control via 2-step along with a timing retard option, which can be triggered by the trans-brake input.
