The DVSA is urging motorists with a vehicle MoT due in August, September, October and November 2021 to bring their vehicle in for a test during May, June or July instead.
The DVSA recently stated that following the issue of MoT extensions during the first lockdown nearly two million cars may be being driven on UK roads without a certificate.
And it urged motorists to carry out basic safety checks on their vehicles which will lead to increased demand for components.
NGK – the leading supplier of original equipment (OE) spark plugs, glow plugs and NTK sensors – says garages should be prepared to deal with the increase in demand by selecting and fitting its market-leading range of NTK Lambda sensors and spark plugs.
NTK Lambda Sensors
- bespoke v quality
NGK advises garages to always go with a bespoke OE-quality Lambda sensor and steer well clear of ‘universal sensors’. A ‘universal’ Lambda sensor is designed to cover as many applications as possible by splicing in the connector from the unit being replaced. In theory, this sounds like a good idea. In practice the potential for a mismatch with the vehicle's system or subsequent premature failure is very high.
Fit for purpose
A worn or failed sensor can result in drastically reduced control of the fuelling system which could result in increased fuel consumption, uneven running, generally poor performance or failure of an MoT emission test, so replacement is good news for the customer, garage and distributor.
Testing times
NGK recommends that the function of the sensor is checked every 20,000 miles or annually. The emissions check as part of the current MoT test samples the exhaust gases to monitor the efficiency of the engine, exhaust system and engine control systems. The Lambda sensor is a vital part of this system and its function is therefore influenced by many other components.
NGK Spark Plugs
- driven to succeed
NGK has been developing spark plug technology since the 1930s and manufactures plugs for every type of automotive engine.
NGK’s vast experience and technology ensures that there is no doubt that it is the world’s No.1 spark plug with drivers benefitting from improved on-the-road performance and fuel economy coupled with lower emissions.
This is why the NGK product range has the right product for nearly every engine and every demand:-
Unique design to guarantee the best possible performance
Wide range of different heat ratings for high thermal endurance
High-performance spark plugs for the newest engine technologies
NGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.
Platinum spark plugs are equipped with a platinum plate on the middle electrode, which ensures a more constant output of the spark plug over the entire service life, even under difficult conditions. Based on its narrow middle electrode, it emits very little spark voltage, discharges the ignition coil, and ensures optimal combustion.
Precious metal spark plugs may be more expensive, but when specified by VMs and used during service and repair they will prevent possible problems due to:-
poor ignition performances
poor tolerance to fouling
higher ignition coil loads
and increasing unwanted emission.
