When selecting the spark plugs, it is important to focus on the manufacturer's recommendations, as well as on the brand and type of candelas that are installed in the car from the factory. However, there are cases where you cannot buy and set original spark plugs, and then the question arises: "How do we match the candles for the car?" Several key recommendations should be taken into account in self-selection. What parameters do you need to match with the spark plugs?
What parameters do you need to match with the spark plugs?
Two main characteristics to be observed when selecting spark plugs: Candle size, thermal performance.
- Candle size,
- A thermal characteristic.
With regard to dimensions, it is necessary that the analogue of the spark plugs with the original match absolutely everything: the length of the part, the diameter and step of the carvings, the size of the hexagon to be installed. In most cases, if these parameters are not met, the candle will simply be impossible to spin.
Another parameter that should be noticed is the gap between the electrodes of the candle. You can find the car-specific settings in the operating instructions. If you have a regulated light candle, you need to adjust it to fit your needs. If the spark plugs are not controlled, it must match the original candle.
The basic thermal characterization of the spark plugs is a potassium number. It indicates the ability of the spark plugs to be heated at different engine temperatures. The calloic number shall be calculated as a measure proportional to the average pressure at which the calibration ignition begins. It is worth considering that the single scale of potash numbers for spark plugs exists only in Russia. Russian spark plugs have potassium numbers 8, 11, 14, 17, 20, 23 or 26.
By the potassium number, the candles are divided on: Hot candles (11-14), candle candles (17-19), cold candles (from 20).
- hot candles (11-14)
- candle (17-19)
- Cold candles (from 20).
The higher the compression in the engine, the greater the potassium number on the candlelight. However, it is not necessary to "overestimate" the potassium number by candlelight and place candles with a parameter above the recommended. If you put candles "hot" recommended, it will lead to a positive-ignition phenomenon. If, on the contrary, put more "cold" candles on the car than recommended, they will simply wither too short a time and quickly get out of order. The spark plugs table

To avoid misfiring the spark plugs when replacing them, you should check the special tables of the analogs. Here is a table of interchangeability of spark plugs from different manufacturers (if it is worth a dash, then the analogue is not available).RUSSIA BOSCH BRISK CHAMPAGNE NEQUEM MAGNETI MARELLI NGK NIPPON DENSOA11.AG11-1.11-342514-9AW919L86406FL41414144RBP5HW16FP5HW16FP514-8BNRBP5HW16FP5HW16FPW16FP5HW16FPW16FP5HW5HW16FP5HW5HW16FP5HW5HW16FP5HW5HW16FP5HW5HW16FP5HW5HW16FP5HW5HW16FP5HW16FP-UA14R-7BCN17FP514-8CW8BNR17Y40514-8CW8FPROF 1440514-8CW8BCN17D40514-8CW8BCN17D40514-8CW8BCN17D40514-8CW8BCN17D40514-8CW8BCN17D514-8CW8CL17N5-FL5LB5EBW17E A14TWO 55 14-8DW8DL17NE-514-8DW8DL5L5L17Y600LFL5L5LPBPBPBPBPBPBPBP517N5-FL5LB5PBPBPBP517N5-FL5L5EBPBPBPBPBP517N5-FL5L5PBP516E 14R-8DWR8DLR17YNR11Y-FL5LPRBPR5E16EXRI-6514R-8DUWR8DCLR17YCRN11YCRC52LF5LCRC52LFP6NPBP6HW20FP6PBP6HW20FP6PBP6ESW20FP6PBP6ESWL7LBP6ESWL7LBP6ESWLBP6P6ESW20F7DL7DLR15YR15YR5SF7LP6ESWLF7LP6ESWLF7DL7DLR15YR15YR15YR5SF7DLR15YR15YR5SF7DLR15YR15YRSF7LP6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPPR6ESWLF7LPRBPR6ESW20PRABPR6ESW20PRABPRBPR6ESW20PRABPRBCPR6ESW20PEPRBCPR6ESW20PEPRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESW20PRBCPR6ESQ20PRBCPR6ESQ20PRABCPR
