LCWRGS Ignition Coil Pack & Spark Plug Kit for Mercedes V6 2006-2012 — 6-Coil/6-Plug OE Fit, Reduced Misfires

LCWRGS complete set of six ignition coil packs and spark plugs designed to restore smooth starts, reduce misfires, and match OE fitment for many 2005–2012 Mercedes V6 engines.

These coil packs and spark plugs are a direct-replacement kit engineered for Mercedes V6 engines used in E350, ML350, C300, R350, SLK350, CLK350, GLK350 and other compatible models from model years around 2005–2012. Built to meet or exceed original equipment specifications, the set includes six coils and six plugs that share OEM-style mounting, electrical connectors, and recommended gap settings. The goal is reliable ignition performance, consistent combustion, and long service intervals while keeping installation straightforward for home mechanics and professional shops.

What vehicles and engine types does this set fit?

This kit fits a range of Mercedes-Benz V6 models from mid-2000s to early-2010s where 3.0L and 3.5L V6 engines were used. Compatibility covers many E, C, ML, R, SLK, CLK and GLK variants listed by year and displacement.

• 2006–2011 E350 V6 3.5L
• 2006–2011 ML350 V6 3.5L, R350 V6 3.5L, SLK350 V6 3.5L
• 2008–2012 C300 V6 3.0L and 2010–2011 C300 V6 3.5L
• 2006–2007 C230 V6 2.5L, 2006–2007 C280 V6 3.0L, 2010–2012 GLK350

How do these coils and plugs improve engine performance?

LCWRGS components are designed to maintain strong spark energy and reliable conduction throughout demanding driving conditions. Upgraded materials and manufacturing tolerances reduce resistance and improve ignition consistency compared with worn factory parts.

• Higher energy output than aging OE coils for firmer combustion
• Conductive copper wire and high-dielectric epoxy for long-term reliability
• Reduced misfires and smoother idle when installed correctly

Are these parts easy to install and what numbers match the OEM?

The kit follows OEM mounting points and electrical connectors to simplify replacement. Each coil and plug has direct-fit part numbers and the set is supplied with a plug gap set to manufacturer guidance so technicians can swap without additional modifications.

• Direct OEM-style fit: IC615, IC665, UF535, 5C1748, C1691, UF585, 07C905115
• Supplied as a matched six-coil and spark plug set for V6 cylinder banks
• Ideal for DIY or professional installation with basic hand tools

What should I expect after replacing coils and plugs?

When properly installed, new coils and plugs typically restore consistent ignition, reduce engine codes related to misfires, and smooth out power delivery. While results vary with engine condition, many users note crisper throttle response and fewer hesitation events after replacement.

• Lower likelihood of misfire-related check engine lights
• Improved idle stability and more consistent acceleration
• Potential for better fuel use when ignition is optimized

Who is this for: This LCWRGS ignition coil pack and spark plug kit is intended for Mercedes owners, independent mechanics, and service shops working on mid-2000s to early-2010s V6 Mercedes models that need a full-bank ignition refresh. It suits drivers noticing misfires, rough idle, or diagnostic trouble codes related to ignition, and also anyone performing preventative maintenance to avoid on-road issues.
