Is spark plug RC12YX the same as RC12YC?
We can find no cross reference for RC12YX to any NGK number, but RC12YC does cross to NGK BCPR5ES .
Are Champion spark plugs gapped?
Today, Champion spark plugs come pre gapped, eliminating the need for this step most times. You should double check that the gap is correctly set; check your owner’s manual to find the distance for the spark plug gap and use a gap gauge or feeler gauge to check the distance.
Is RC12YC a resistor plug?
The Briggs 491055T is a RC12YC plug which is a resistor plug. The Briggs 694385 is a RC14YC plug which is a resistor plug. The K6RTC appears to be inductive resistor plug. Inductive resistance plugs usually read around 40 ohms but on a 20 kilo ohms scale will look more like zero ohms.
Do you need a spark plug gap tool?
You need a feeler gauge to gap your spark plugs properly. Gap new as well as old spark plugs, even if the package says that the new plugs are “pre-gapped.” To avoid problems, work on only one plug at a time, in cylinder sequence order.
Can I use RC14YC instead of RC12YC?
EITHER RC12YC or RC14YC will work. But for best results use NGK BKR5E or BKR6E. They last longer and are less prone to fouling.

NGK Pro-V Spark Plug BKR5E (RC12YC) fits Champion, NGK and Autolite.
What is the best spark plug gap?
For most racing applications, you usually want the plug gap to be between 0.020 and 0.040 of an inch. Most engine builders seem to settle around 0.035 of an inch. Factors such as the type of ignition you run, cylinder heads, fuel and even timing can affect how much gap will work best for you.
What is the difference between champion rc12yc and RC14YC?
What is the difference between rc12yc and rc14yc spark plug? The higher number is a slightly hotter spark type plug. The RC14YC4 is now the standard plug for the 990/992 Generac engines. The 999 in the new 16-22kW Evolution (7000 series) units and older 20kW units are still using the cooler RC12YC4 plugs.
