What do Champion spark plug numbers mean?
CHAMPION SPARK PLUGS DECODED The combination of letters and numbers assigned for every Champion spark plug is a logical formula which indicates the major features of its design.
 Heat Range – The middle number indicates the heat range of the spark plug, the higher the number the hotter the heat range..
What happens if I use a colder spark plug?
The colder type removes heat more quickly, and will reduce the chance of pre-ignition/detonation and melting or damage to the firing end. (Engine temperature can affect the spark plug’s operating temperature, but not the spark plug’s heat range).
What are heat ranges for spark plugs?
The degree to which a spark plug disperses the heat it receives is called its “heat range”. Spark plugs with a high degree of heat dispersal are called high heat range (cold type) and those with a low degree of heat dispersal are called low heat range (hot type).
What is the end of a spark plug called?
When the spark plug firing end (tip) temperature exceeds 800°C, pre-ignition originating from the overheated insulator ceramic can occur.
What are the numbers on a spark plug?
The plug number is used to decode the spark plug and the stock number is used by our sales associates to aid in stock management, as alphanumeric numbers are harder to inventory. The stock number is a random 3-, 4- or 5-digit number and has no relation to heat range or plug type. An example is DPR5EA-9; 2887.
What is the recommended spark plug gap?
The gap setting is different for each vehicle but most are somewhere between 0.028″ and . 060″. Consult the owner’s manual or Champion ® catalog to find the recommended setting for the vehicle you’re working on.
What is the difference between NGK bp6es and bpr6es?
The only difference between BPR6ES-11 and BP6ES-11 is that the BPR6ES-11 has a built in resistor (R) to reduce RF noise that can leak into other electronics due to the high voltage.
What happens if the spark plug gap is wrong?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.
What do NGK Spark Plug numbers mean?
Typically the heat range for NGK Spark Plugs varies from 2-11. This number indicates the thermal characteristics of a spark plug, or how ‘hot’ or ‘cold’ a spark plug is. … This means the spark plug will heat up easily and reach its optimal operating temperature.
What does running a hotter spark plug do?
A hotter plug does what is says, it runs hotter. This will not give any more power and neither will a too cold plug. … If the current plug is too hot then the tip may be melted or deformed. If the plug is too cold then you may have excessive build up (which can also be caused by burning oil or a rich air-fuel mixture).
Are all lawn mower spark plugs the same?
Every lawn mower and lawn tractor is built a little differently, and mowers with engines made by Briggs & Stratton are no different. Spark plugs are available in varying sizes, and you could do damage to the engine if you don’t use the right one, according to Briggs & Stratton.
How do you read a NGK Spark Plug code?
The first letter of the NGK spark plug code (in this case a “D”) indicates the thread size of the spark plug. There are three spark plug thread sizes currently being used in motorcycles and ATVs. “B” indicates a 14 mm x 1.25 pitch size, “D” indicates a 12 mm x 1.25 size and “C” indicates a 10 mm x 1.0 size.
Do I need a hotter or colder spark plug?
When making spark plug heat range changes, it is better to err on the side of too cold a plug. Running too cold a plug can only cause it to foul out, whereas running too hot a plug can cause severe engine damage.
When should I run a hotter spark plug?
Use a colder heat range for leaner air/fuel mixtures. Rich air/fuel mixtures can cause the plug temperature to dip, allowing carbon deposits to build up on the tip. Use a hotter heat range for rich air/fuel mixtures. Advanced ignition timing: In general, advanced ignition timing will raise the spark plug temperature.
Can I run a hotter spark plug?
A plug with a hotter heat range (lower NGK numbers) retains more heat, so it can burn off deposits better, and therefore resists fouling. However, in the wrong conditions a plug with a hotter heat range can retain too much heat, and cause detonation or actually melt the electrode.
What does NGK bpr6es fit?
The NGK BPR6ES is the correct spark plug for most Honda and Honda clone lawn and garden engines. This includes the Honda GC160, GC190, GX270, GX390, some Briggs & Stratton engines, Harbor Freight Predator, and the R200, R301, and R420 Raven engines found on RuggedMade log splitters.
What is the difference between NGK bpr5es and bpr6es?
The BPR5ES will run hotter than the BPR6ES. Running a BPR6ES in an engine designed for a BPR5ES may cause premature fouling, and running a BPR5ES in an engine designed for a BPR6ES may cause detonation. For more information about decoding NGK plugs, you can follow the link at the end of this post.
Can spark plugs cause check engine light?
Another common reason for seeing a check engine light is faulty spark plugs or plug wires. Your spark plugs and wires are what ignites the fuel/air combo to make your engine turn. Old or faulty plugs and wires can cause weakened engine performance and poor fuel economy at best.
