What does the L mean on a spark plug?
Resistor type spark plugs reduce the amount of radio frequency interference (rfi) that can cause ignition misfires and static on the radio, if so equipped. The second letter of the Champion spark plug code (in this case an “L”) indicates the thread size and reach of the spark plug.
What does CR8E mean?
The 8 is what is called a hotter plug and recommended for the cooler climate of northern Europe. The 9 is a colder plug and recommended for the warmer climate of southern Europe. The colder plugs conduct the heat away from the plug faster than the hotter plugs. Cr8e is the recommended plug for UK and Ireland.
What does the R stand for on 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.
Can I use a bpr5es instead of an bpr4es?
Can i run ngk bpr4es spark plugs instead of the bpr5es that came out of my ferris riding zero turn mower safely? Hi Dan, Thank you for your question. It is recommended to use the spark plugs listed for your model number, so your engine can run correctly.
What is the P in BPR9ES?
Free Member. The P stands for platinum tip.
What is the difference between NGK CR8E and CR9E?
The CR9E is a colder sparking plug than the CR8E. Numbers going up generally mean colder plugs. If you ride “conservatively”, it may be too cold for you, but if you “thrash” your bike near its rev limiter, it will work fine.
What size is a CR8E spark plug?
Hex Size: 16mm (5/8″) Reach: 19mm (3/4″) Gap: 0.8mm (0.03″) Thread Pitch: 1mm (1/16″)
Which NGK Spark Plug is hotter?
Is that hot? The heat range of a spark plug is indicated by the number in the plug’s identification sequence. On NGK spark plugs, the lower the number the hotter the plug (higher numbers are colder). Thus, your NGK BR9ES is colder than a BR8ES.
Which is better a resistor or non resistor spark plug?
Most resistor spark plugs use a monolithic resistor, generally made of graphite and glass materials, to filter the electrical voltage as it passes through the center electrode. Since resistor type plugs actually “resist” some of the spark energy, non-resistor type plugs actually deliver a more powerful spark.
What is the difference between a BPR5ES and an BPR4ES spark plug?
The difference between NGK BPR5ES and BPR4ES is their individual terminal type. The terminal of BPR5ES is a removable nut-style one, and the BPR4ES has a fixed and solid terminal. Therefore, the BPR5ES has to be screwed to mount in its place.
