Holley Terminator Stealth EFI Master Kit


With modern fuels containing more and more ethanol, it is becoming hard for the carburetor to be as reliable as they once were. With fuels boiling point approaching all times lows of anywhere from 90-130 degrees. This causes major issues with carbs vapor locking. Causing you to get stranded in your vehicle on a hot summer day. If you have been hesitant about switching to EFI because you like the traditional look of a carburetor. There is no more need to worry! Holley has you covered with the new Terminator Stealth Throttle Body Fuel injection System.
