spark plug -NARAKU- 14-R7-LS (BR7ES)
Part no.:
NK14R7LS
Description
Naraku spark plug as it is also mounted in the vehicle from the factory. Heat value and plug structure correspond to the original.
Produced according to OEM guidelines of Japanese vehicle manufacturers for a perfect repair and longevity.
The service life of a plug is determined by the fuel type, engine condition, operating times and engine temperature. For 4-stroke engines from 250cc, the plugs should be cleaned or changed after 6000km. With less displacement, especially 2-stroke, approx. every 2500km. After this mileage, oil carbon deposits lead to starting difficulties and power loss caused by the spark plug. Increased short-distance operation and poor engine oil quality can shorten the intervals.
Width across flats: 20.8mm
Thread diameter: 14,0mm
Thread length: 19,0mm
Electrode gap: 0,8mm
Resistance: suppressed, 5kOhm
OEM numbers for comparison purposes:
NGK: BR7ES
Bosch: WR 5 CC / 0 242 245 521
Champion: OE 098 / RN 4 / RN 4 C
Denso: W 22 ESL / W 22 ESR / W 22 ESRL / W 22 ESRU / 3098
14 = B thread diameter 14mm
