NGK ignition coil and lead selection is simple via the Niterra Part Finder at www.ngkpartfinder.co.uk/catalogues/cars ngksparkplugsuk Niterra UK Ltd YouTube ngkntk_uk Niterra UK Ltd ngkntk.com/uk Misfires, rough idling or sluggish performance? These issues may signal potential ignition lead or coil failure. Or what if those symptoms pointed to problems with fuel injectors, or sensors, or mechanical wear? This diagnostic complexity can lead to unnecessary part replacements and costly repeat visits. A detailed investigation is crucial before replacing components. With Niterra, quality replacement is straightforward, thanks to our trusted NGK range. Understanding the interplay between coils, leads and other ignition components is essential to accurate diagnostics and effective repairs. PROACTIVITY PAYS Modern ignition systems are evolving to boost combustion efficiency. Dual spark technology, for example, optimises power delivery and ensures smooth running but places extra strain on ignition coils. Ignition coils and leads are built to last but operate under extreme conditions and, like tyres, should not be pushed beyond their lifespan. Ignoring early warning signs or delaying replacement can result in complete component failure, increased emissions and damage to other engine parts. Workshops must therefore select replacement components carefully to ensure compatibility and reliability. Durability is key – inferior parts may work initially but degrade faster, leading to recurring faults and frustrated customers. THE CASE FOR QUALITY NGK, Niterra’s flagship brand, is synonymous with ignition excellence. Our world-renowned spark plugs depend on equally high-quality ignition coils and leads to provide the essential spark that drives petrol engines. All of NGK’s ignition coils are engineered for optimal fit, excellent vibration resilience and superb shortcircuit protection. The range includes: • Distributor Coils • Block Coils (with dual high-voltage output options) • Pencil Coils (with single or double spark technology) • Coil Systems (also known as ‘rails’) NGK leads deliver dependable performance by conducting high ignition voltage with minimal loss. Designed to resist moisture, heat (up to 220°C) and engine vibration, these leads ensure consistent performance even under demanding conditions. This attention to quality means that workshops can rely on NGK components to reduce rework and keep vehicles running efficiently. Diagnosing ignition issues isn’t always straightforward, but choosing quality replacement parts is. NGK ignition coils and leads provide the durability, performance, and reliability workshops need to keep their customers on the road. TAKING THE LEAD Niterra UK Ltd outlines how workshops can enhance their operations with NGK ignition coils and leads.
