Fuel Injector Genuine Renault Clio 2 RS / Gr.N / Cup

The dangers of a tired injection system on your Clio 2 RS

Failing to replace a faulty injector on a Renault Clio 2 RS F4R engine is a major risk. Over time, clogging or internal wear alters the fuel spray pattern. Poor atomization leads to a lean air-fuel ratio, which spikes temperatures inside your cylinders. The consequences? A noticeable loss of power, misfires, and most importantly, a real risk of piston failure or total engine breakdown during intensive track or rally use.

The importance of the ITG M60 marking and Genuine Renault quality

Many counterfeit parts are circulating on the market. Only the Genuine Renault injector bearing the ITG M60 marking ensures the exact flow rate and resistance to fuel pressure required for Jean Ragnotti, Cup (X65), and Group N versions. By choosing this official reference, you avoid idle instability and acceleration flat spots that ruin the driving pleasure of your sports vehicle.

Performance Optimization and Engine Maintenance

Replacing your petrol injectors is part of a rigorous maintenance schedule for anyone wishing to maintain the original performance of their hot hatch. For a reliable engine personalization, it is recommended to replace all four injectors simultaneously to balance the richness across every cylinder.
