NGK Iridium Spark Plug - Renault Clio 4 RS (Trophy & Sport) (1 unit)

The risk of neglected ignition on your Clio 4 RS

The 1.6 Turbo engine of the Renault Clio 4 RS (Trophy or Sport chassis) demands absolute spark precision. By keeping worn or standard quality spark plugs, you expose your engine to frequent misfires under high boost pressure. Without switching to NGK Iridium technology, you accept a latent power loss, sluggish cold starts, and an increase in fuel consumption. Don't let a fouled spark plug compromise the health of your engine block and ruin the driving pleasure of your performance car.

The absence of a powerful and stable spark can lead to poor combustion, causing premature valve fouling and degradation of your catalytic converter. By delaying this replacement, you risk seeing your vehicle lose its punch and its value in the premium market.

Iridium Technology: Performance meeting Reliability

The NGK Iridium spark plug stands out with its extremely fine center electrode, allowing for a lower required ignition voltage while producing a more concentrated spark. This technology is crucial for the customization of your engine management (Stage 1 or Stage 2), where thermal constraints are significantly increased. It ensures a much longer lifespan than conventional plugs, guaranteeing consistent performance mile after mile on your Clio IV RS.
