What is NGK spark plug CMR7H 3055112R?
NGK spark plug CMR7H 3055112R is an original consumable component of the renowned NGK brand, responsible for creating the spark that ignites the fuel-air mixture in the combustion chamber of the engine. This is one of the key components that directly affects easy starting, operating dynamics, operating culture and engine life. High-quality materials and precise workmanship make this candle resistant to harsh working conditions - high temperature, pressure and impurities produced during combustion.
Thanks to its design adapted to modern two-stroke and four-stroke engines of small capacity, the CMR7H model will be ideal for equipment working in the garden, orchard or on the allotment, where the following counts reliability in all conditions - For both short and long work cycles.
Where is the NGK CMR7H 3055112R spark plug installed??
Spark plug NGK CMR7H is mounted directly in the cylinder head of the internal combustion engine. Screwed into the socket of the candle (with appropriately selected threads) ensures the tightness of the combustion chamber and the ideal position of the electrodes in relation to the fuel-air mixture. This model fits m.in. for the following machines OLEO-MAC:
- BC 241 H
- BC 241 HL
- HC 246 P
- HC 247 P
- HCS 247 P
- BC 241
By maintaining the appropriate 10 mm external thread,thread length 12.7 mm and standard 16 mm wrench size, candle replacement is quick and hassle-free. Simply disconnect the ignition cable pipe, unscrew the old spark plug and screw in the new one, making sure to maintain the correct tightening torque.
Such a solution makes it possible for the user - even without advanced technical knowledge - to restore full functionality of the device on their own, in a few minutes, without visiting the service center.
Use of NGK CMR7H 3055112R candle in daily operation
Spark plug NGK CMR7H has been developed for heavy-duty equipment working in the garden, forest and home workshop. Great for:
- Trimmers and trimmers - Ensures fast startup even after a prolonged shutdown, which is crucial for seasonal use of equipment.
- Hedge trimmers - stable spark translates into even engine operation, which makes precise shaping of hedges and ornamental shrubs much easier.
- Power saws and secateurs - high resistance to dirt and carbon build-up allows the engine to maintain full power when cutting thick branches or preparing firewood.
In practice, this means that when you choose an NGK CMR7H spark plug, you get a a reliable component, which translates into a lower risk of failure at key moments - during mowing, pre-season garden clean-up or intensive orchard maintenance work.
NGK spark plug CMR7H - construction, durability and key benefits
Spark plug NGK CMR7H 3055112R is distinguished by a finely tuned design that ensures long and trouble-free operation:
- 1 mass electrode - simple and effective design promotes easy cleaning and stable spark formation. This is important especially in engines operated in dusty environments, typical of gardening and forestry work.
- Nickel center electrode - The use of nickel increases resistance to wear and corrosion, which directly translates into longer service life of the candle and less frequent need to replace it.
- SAE Permanent Link - secure and stable attachment of the ignition pipe guarantees uninterrupted delivery of high voltage, minimizing the risk of spark jumping in the wrong place or occasional ignition interruptions.
In addition, the plug is de-coupled (10 kΩ), which significantly reduces electromagnetic interference. This is important not only for the electronics of the device itself, but also for the comfort of working near other machines or equipment sensitive to interference.
In everyday use, this means less frequent engine stalling under load, smoother acceleration and less susceptibility to "flooding" when repeatedly trying to start a cold engine. For the user, this translates into saving time, nerves and money - the device simply works when needed.
NGK CMR7H 3055112R - comfort, fuel economy and engine protection
High quality workmanship of the candle NGK CMR7H has a direct impact on the economy and culture of horticultural equipment:
- Easy starting in low and high temperatures - properly selected thermal parameters of the candle and precise setting of the electrodes make the engine start efficiently both on a cool morning in early spring and during hot summer days.
- Stable rpm and lower emissions - even combustion of the mixture translates into quieter, "more even" engine operation and reduced smoke, which will be appreciated by users working near residential buildings.
- Lower fuel consumption - complete fuel combustion means less fuel consumption with the same operating power. During the busy gardening season, this can yield tangible savings.
With the proper selection of a spark plug and its regular replacement, the engine is better protected from excessive wear. The amount of carbon build-up on the piston, valves and in the combustion chamber is reduced, prolonging the life of the drive unit and reducing the risk of costly repairs.

- Proper tightening torque - Tightening the candle with feeling, according to the manufacturer's recommendations, guarantees tightness without the risk of damaging the threads in the head.
By following these guidelines, the user can count on maximum long service life of a single candle and a significant reduction in unplanned downtime in equipment operation.
FAQ - Frequently asked questions about NGK CMR7H 3055112R candle
Question 1: Does the NGK CMR7H 3055112R spark plug only fit OLEO-MAC machines??
Not. Although the description lists specific models OLEO-MAC (BC 241 H, BC 241 HL, HC 246 P, HC 247 P, HCS 247 P, BC 241), the plug can also be used in other equipment, if the engine manufacturer provides for the use of a plug of type CMR7H with the same parameters of thread, length and electrode gap. However, it is always a good idea to compare the markings with the device instructions.
Question 2: How often should the NGK CMR7H spark plug be replaced??
Frequency of replacement depends on the intensity and operating conditions of the device. In typical horticultural applications, it is recommended to check the condition of the candle at least once a season and replace it every 1-2 seasons, or earlier if signs of wear are visible (burned electrodes, cracks in the insulator, difficulty starting).
Question 3: Is the candle pre-set and ready for installation?
Yes, a candle NGK CMR7H is factory-prepared for installation, but before screwing in it is recommended to check the electrode gap and its possible correction according to the engine manufacturer's recommendations. This will allow you to get the best ignition performance.
Question 4: Does the NGK CMR7H candle affect fuel economy??
Yes. An efficient and properly selected spark plug contributes to a more complete combustion of the fuel-air mixture, which can lower fuel consumption and reduce smoke. A faulty or worn-out spark plug causes incomplete combustion, loss of power and higher burn rate.
Question 5: How to recognize that a plug needs to be replaced?
Symptoms of a worn-out spark plug may include: difficulty starting the engine, loss of power, rough idle, frequent stalling under load, excessive smoke or visible mechanical damage (cracks in the insulator, severely burned electrodes). In such situations, it is recommended to install a new NGK CMR7H spark plug.
Question 6: Is the NGK CMR7H candle unbarked?
Yes, the candle is equipped with a 10 kΩ resistor, thus reducing electromagnetic interference, improving the stability of the ignition system and minimizing the impact on other electronic devices in the vicinity.
When choosing nGK spark plug CMR7H 3055112R, you are investing in reliability, long life and operational safety of your gardening machinery. This is a solution that will be appreciated by both the amateur user and the professional who expects the highest quality and certainty of operation in all conditions.
