Yes spark plugs must be gapped to the vehicle specifications. Different vehicles call for a different gap.
A 2005 Honda Element should have a spark plug gap that is set at .044 inches. Almost all Honda engines are set with the same spark plug gap.
The spark plug gap for a 1994 Toyota Rav4 should be set at 0.044 inches. The gap on the spark plug is usually preset.

The spark plug gap for a 1984 Toyota Corolla should be set at .044 inches. The best spark plug for this vehicle is an Iridium plug.
The spark plug gap for an AR135 spark plug on a 350 SBC should be set at .034 inches. This is equal to .86 mm so a spark plug set to .9 mm should work correctly.
According to my HELMS manual...the spark plug gap is set at 1.1mm or 0.043 inches.
The spark plug gap for a 2003 Buick LeSabre should be set at .060 inches. The best spark plug for this vehicle would be an Iridium plug.
