the oem pedal they're talking about is on the brake. the gas pedal doesn't have a rubber cover on it to start with like the brake does, so there's nothing to pop off that one. just put the gas pedal cover right over the pedal--you have to wiggle it around a lot and pull up on the rubber to get it to stretch over the pedal. and i do recommend using some liquid soap and water, it makes it a lot easier to get it on.
