Is RC12YC same as QC12YC?

Is RC12YC same as QC12YC?

From what I can find the two plugs have the same heat range so are interchangeable without any difference in mechanical engine performance. BUT if you have a fuel injected engine you should use the QC plug. It’s internal electrical construction is different to work properly with fuel injection systems.

Does RC12YC replace QC12YC?

446777 Type 0246-E1 Code 021212YG01545 engine on a Craftsman lawn tractor. The Craftsman owners manual says it takes a Champion QC12YC spark plug. Supposedly, the Champion RC12YC plug is an acceptable substitute because it crosses with the Briggs 491055S plug that is shown in the IPL for this engine.

What spark plug is the same as champion QC12YC?

BKR5E NGK Spark Plug Replaces Champion QC12YC, Briggs & Stratton Husqvarna Kohler.

What does Champion RC12YC fit?

RC12YC Spark Plugs

What does Q mean in Champion Spark Plug?

electromagnetic suppression
“Q” Type: Uses a wire wound inductive coil (or electromagnetic suppression) to reduce RFI without negatively affecting ignition performance. “Q” type suppressor plugs are specified for most Evinrude and Johnson outboard engines with CDI.

What NGK Plug replaces RC12YC?

NGK CS6 Series Spark Plug Replaces Champion RC12YC.

What does R mean in NGK spark plugs?

[R] Resistor – If an R is present, this indicates a resistor type spark plug. Resistor type spark plugs reduce the amount of radio frequency interference (RFI) that can cause ignition misfires and static on the radio.

What do the letters stand for on NGK spark plugs?

The first letter of the NGK spark plug code (in this case a “D”) indicates the thread size of the spark plug. The letter “J” indicates a 12 mm x 1.25 size with two ground electrodes. The “P” indicates a projected tip spark plug design that moves the spark deeper into the combustion chamber.

What is the NGK equivalent to a champion RC12YC?

The NGK I stock as an equivalent to the RC12YC is the BCP(R)5ES (6130).

What’s the difference between a champion RC12YC and RC14YC?

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. The ‘4’ at the end is the spark gap that’s preset at the Champion factory.

Is the RC 12yc the same as the qc12yc spark plug?

The RC12YC electrode is a fat cylinder like most spark plugs, while the electrode of the RC12YX is cut down to about half of the diameter. I’d guess the special RC12YX makes it easier to start the engine on a single pull. What spark plug cross references with kohler 1413211?

Can you use rc12yc plugs on a lawn mower?

Also (Resistor Types) explains why you cant use RC12YC in an engine that requires QC12YC plugs. Interesting. It wouldn’t have occurred to me.

Is the QC plug the same as the RC plug?

From what I can find the two plugs have the same heat range so are interchangeable without any difference in mechanical engine performance. BUT if you have a fuel injected engine you should use the QC plug. It’s internal electrical construction is different to work properly with fuel injection systems.

Do you need a QC plug for fuel injection?

BUT if you have a fuel injected engine you should use the QC plug. It’s internal electrical construction is different to work properly with fuel injection systems. The QC plug reduces noise in the electrical system that might effect sensitive electronic circuits. . Good call on the potential for EFI K4.
