Spark plug NGK BR7HS 4122

NGK BR7HS ignition spark plug — a 14 mm thread plug with a radio-suppressor resistor. The NGK number 4122 is printed on the end of the box, and on the side is the label "BR7HS · Zündkerze NGK · entstört BR7HS".

• NGK number 4122 — it is printed on the box and is enough to repeat the order
• The letter B in the code — 14 mm thread; the letter R — radio-suppressor resistor, on the box this is written in German as "entstört"
• The number 7 — the heat range indicator on the NGK scale: a higher number means a colder plug
• The letter H — 12,7 mm thread length, that is how far the plug reaches into the head
• Also in the range: BR8HS 4322 — the same thread and the same thread length, just heat range 8

We write only what we know. NGK marking tells you the thread diameter, the resistor, the heat range and the thread length, but it does not tell you which machine the plug is for — we cannot derive that from the code and we do not write it. Before ordering, copy the marking off your old plug or measure its thread and write to us — we will check it before you order.
