In 1971 I tried "fire injectors" (in a 383 Road Runner) that were advertised by J.C.Whitney mail order to increase horsepower, fuel mileage, and even raise the idle speed because they burned more of the raw fuel. Liars.
Thank you for playing the game.
I read the same BS in the Warshawski/Whitney catalogs and never bit.
But they wrote some great copy to sell them plugs...
