MHP-Plugs
MOTORTECH High Performance Spark Plugs
The expansion of MOTORTECH’s state-of-the-art ignition controllers is driven by the latest developments of modern spark ignited gas engines. The operation of these high performance engines with advanced compression rates and very efficient lean-burn combustion systems require much higher voltages to allow a perfect and effective combustion. MHP spark plugs are designed to meet the requirements, both of modern and common engine developments and reliably deliver highest voltages and thus a strong spark down into the combustion chamber. The J-type electrode design with IRIDIUM alloy discs on center and ground electrode provides reliable combustion and increased spark plug life and helps to reduce service costs due less spark plug changes.

MBP-Plugs
MOTORTECH Bridge Spark Plug
Modern gas engines are permanently operating under absolute extreme conditions with an effective mean pressure of more than 20 bar, with highly corrosive fuels (H2S) and lean mixtures – simultaneously demanding longer life periods. The MOTORTECH MBP1800 spark plug uses an innovative, highly solid electrode design, thus granting three times longer lifetimes than any traditional J-gap spark plug can do.
2) Call MOTORTECH or your nearest MOTORTECH sales partner for information about the range of application.

XT-Plugs
MOTORTECH Extended Barrel Spark Plugs
For certain applications extended barrel spark plugs are required. For example when the operator cannot get a conventional spark plug down the narrow spark plug well, he will need a special product that allows him to torque the plug from the top end. MOTORTECH offers an improved product to the market. Several of the known problems of products made by competitors are eliminated.
Besides an increase in reliability the spark plug run time needed to be extended. To achieve this, MOTORTECH uses base spark plugs with Iridium alloy (J-type) on center and ground electrode. MOTORTECH extended barrel spark plugs can be ordered in different lengths, terminal styles or with an integrated ignition cable.

Spark Plug Cleaning Kit
Regular maintenance is required to achieve the maximum service life in particular with high price spark plugs with precious metal alloys.
Apart from readjusting the electrode gap, the spark plug should also be freed from deposits and residues that have formed during operation. By using the MOTORTECH spark plug cleaning kit these impurities can be removed easily and gently in the electrode area and on the thread within a regular maintenance interval.
This will increase spark plug service life and cut maintenance costs.

Spark Plug Gap Setting Tool
The gap between the center and ground electrodes is of fundamental importance for clean combustion as well as the optimal functioning of any spark plug. During the operation of a gas engine, however, the gap between the electrodes can increase, e.g. because of spark erosion, which can lead to increased voltage requirements or even misfiring.
The electrode gap should be re-adjusted at regular maintenance intervals in order to maximize the service life of spark plugs, especially for high-priced industrial spark plugs.
MOTORTECH’s innovative spark plug gap setting tool provides every gas engine operator or employee of a service company with a smart tool to professionally adjust the electrode gap on-site in a material-conserving manner.

Extended Barrel Magnetic Spark Plug Sockets
When it comes to service of a gas engine, the exchange of a spark plug is one of the easier tasks. However there are a few things you need to consider. Especially with modern high-end spark plugs it is essential to carry out a service with a tool for professionals and to avoid damage when the spark plug is screwed in or out.
MOTORTECH offers a complete range of extended barrel magnetic spark plug sockets in various lengths for all types of HEX. Integrated strong magnets hold the spark plug securely in any position, which guarantees an easy assembly and disassembly work especially on large engines with deep spark plug wells.
