Ignition coils are used to create a spark at the spark plug to instigate combustion in an internal combustion engine. The ignition coil is basically a transformer that coverts the low level voltage from the battery into the much higher voltage required to jump the spark plug electrodes.

Traditionally ignition coils where ‘wet’ coils, they consisted of some primary windings of several turns of a thick wire and then 1000’s of turns of a much thinner wire wrapped around an iron core, this was then put into a case and filled with oil to provide insulation and heat dissipation.

Although all ignition coils use this same principle they have evolved over time and a typical modern ‘dry’ coil utilises the same transformer setup but the casing around it is filled with epoxy resin to provide the insulation and heat dissipation.

Many modern vehicles use a coil per cylinder setup, this means that each spark plug has its own coil directly attached to the top of it thus providing a very efficient spark whilst removing the need for HT leads. These compact coils often use rare earth magnets in the central core to increase output voltage and maintain a strong spark in the limited physical space available.

SMP Europe's coil-on-plug assemblies are engineered and tested to meet or exceed OE standards for spark energy, impedance, and durability. The core has an internal neodymium permanent magnet surrounded by grain-oriented magnetic laminated steel for maximum voltage output at all speeds.

The primary winding has a 200°C insulated coating over a premium 25 gauge copper wire, allowing low voltage to generate a strong magnetic field. A high temperature insulation coating prevents shorts between the windings under extreme operating conditions.

The bobbin is made from fibre reinforced polyphenylene oxide glass material which has outstanding dielectric properties to keep the voltage directed along the correct path providing long life under extreme high-voltage conditions.

The high impact case is tough and durable with excellent thermal qualities and the high temperature spark plug boot contains a conductive stainless steel spring with radio static noise suppressor both are built for long life in all operating conditions.

The ignition coil converts a low voltage current to high voltage energy that is delivered to the spark plug to ignite the air fuel mixture within the cylinder. A coil-on-plug is designed to perform the functions of both the ignition coil which creates the spark energy, and the spark plug wire set that is designed to contain and deliver the high voltage energy to the spark plug.

Sometimes known as high-tension (HT) leads or Spark Plug Wires, Ignition leads carry an electrical current from the ignition coil into the spark plugs, ultimately, lighting the fuel and air within the combustion chamber of the engine.

SMP Europe’s range of Original Fit Ignition Leadsets contain over 875 references making it the most comprehensive range of OE fit sets available. Our portfolio can be purchased across all of our primary brands,

Intermotor, Lucas, High Volt and Electrospark. We are constantly monitoring the aftermarket to update our offerings to ensure our customers remain up to date and have the sets they need for every repair.

Designed and developed in the UK at our Nottingham Centre of Engineering Excellence, the majority of sets are manufactured using 7mm or 8mm full silicone and copper core cable, however the range also includes 5mm cable O.E sets to cover the Japanese and Korean vehicle parc.

Double silicone cable is used for maximum radio suppression, resistance to temperature, water and oil degradation and chemical attack. All terminals are machine crimped to ensure strong and reliable connections. All spark plug boots and terminal covers are moulded from silicone to give a water tight seal.

The product is extensively tested. These tests include "pull off" tests, both hot and cold, to check that all terminals and connections are satisfactory and a hi-voltage saline solution immersion test to check for current seepage.

A critical component on the modern vehicle, these sensors measure the air entering the engine and convert the information into an electrical signal for the ECU to determine load and calculate the correct fuelling and ignition timing. 

SMP Europe has built on over 50 years experience in the design and manufacture of Engine Management components, now renowned as one of the leading manufacturers of aftermarket Air Mass Meters, providing quality, dependable components across one of the largest ranges available in the industry. 

Designed and developed in the UK at our Nottingham Centre of Engineering Excellence, using the latest techniques and technologies, our Air Mass Meters are wire bonded to ensure durability, and tested on bespoke in house designed equipment to meet or exceed OE performance standards. 

Whilst many aftermarket solutions contain traditional technologies, our parts are manufactured with the latest and best materials, with custom designed electronics, giving our range a proven record for high performance over a long service life.

A lambda or oxygen sensor relays information to the ECM using the oxygen content in the exhaust which enables the ECM to control the air/fuel mixture for efficient combustion. SMP Europe sensors undergo 100% testing, ensuring better quality, increased confidence, and improved performance. In addition, SMP Europe sensors are thermally conditioned, burning off any contaminants to prolong unit life and performance.

Manufactured with a stainless steel shell that reduces rusting and provides greater dependability. The centre ceramic element is composed of Zirconium Oxide, Alumina and Yttrium Oxide.

The platinum coating is applied using vapor deposition to ensure an even application.

A Spinel coating on the outer platinum layer prevents solid particles in the exhaust gas from damaging the platinum coating.
 
SMP Europe manufactures a comprehensive programme of OE style Zirconia and TitaniaOxygen Sensors covering over 3500 vehicle applications. Available in single, twin, three and four wire versions to suit the application. SMP Europe Oxygen Sensors are made to extremely high standards to ensure they match OE performance criteria. In addition to its Original Equivalent products, SMP Europe also offers a Universal Oxygen Sensor range designed to provide an extremely economical solution, with only minimal installation work required, plus a universal system comprising just 4 Ziconia Sensors plus 74 adaptor leads. This system provides an OE style solution for the aftermarket without the need to hold large stocks of individual parts

SMP Europe’s range of EGR Valves has been developed for several years, to improve aftermarket EGR solutions. Our research into exiting aftermarket solutions showed that in all cases existing electronics were unreliable and in the worst cases missing components altogether. 

SMP Europe’ solution, built on over 50 years experience in the design and manufacture of Engine Management components, was to replace the electronics with custom designed PCB’s, developed in our state of the art research and manufacturing facility. 

Designed and developed in the UK at our Nottingham Centre of Engineering Excellence, using the latest techniques and technologies, our range of EGR Valves offer a fully temperature compensated design, with each unit individually calibrated on bespoke end of line testing equipment to meet or exceed OE performance standards. 

Whilst many aftermarket solutions contain traditional technologies, our parts are manufactured with the latest and best materials, with custom designed electronics, giving our range a proven record for high performance over a long service life.
