NGK BKR7E Spark Plug – Stock No. 6097
The NGK BKR7E is a reliable copper-core, resistor spark plug for petrol engines that need a colder heat range. It helps control combustion temperatures in tuned or hard-driven engines, giving a consistent spark under load.
Its simple nickel alloy tip and copper core conduct heat well. That helps reduce the risk of pre-ignition and misfire when boost or cylinder pressures increase. It is also easy to gap. Expect shorter service life than iridium, but strong performance and good value.
- Colder heat range (7) for tuned or track use where extra heat control is needed
- Strong spark and stable idle with resistor design for clean signal to the ECU
- Gasket seat and 16 mm hex for easy installation with common tools
