Sniper EFI

The company Holley introduced a new category called the Sniper EFI. A reasonably priced product enables customers to take advantage of EFI while still having enough money to finish or upgrade the rest of their bikes. It is ideal for street rods, muscle cars, off-road trucks, and any carbureted vehicle. Cold starts, hesitations, vapor lock, and flooding are no longer an issue. It's excellent for any car in standard with a 2300 Holley Flange, including some Fairlanes, Galaxies, Falcons, Comets, F100s, Javelins, Rebels, Mustangs, Thunderbirds, Cougars, and more. The best thing is its affordable price range because it allows one to benefit from EFI while still having money left over to finish or enhance their ride. It can also be easily converted to a 4bbl intake with a square flange or Q-jet flange using a Mr. Gasket adapter.
