Mechanical Throttle Body Clio 2 RS - X65 Cup - GR N / Clio 3 Cup

The critical risk of a worn out or unavailable throttle body on the market

The aging of original mechanical components on racing or track-day engines creates a major issue: a permanent shortage of factory-new parts. Keeping a worn housing on your engine block exposes you to throttle hesitation, a lack of intake sealing when closed, or a butterfly valve jamming under full load. Missing out on this high-precision mechanical throttle body reproduction means taking the risk of leaving your vehicle sidelined for the season, simply because you cannot replace a permanently discontinued factory part.

Rigorous manufacturing for race-spec Renault Sport engines

Developed specifically to meet the high demands of motorsport, this premium technical component restores your engine's original behavior and responsiveness. Manufactured to strict machining tolerances to eliminate shaft play or intake vacuum leaks, it advantageously replaces factory hardware that has been fatigued by years of thermal cycles on the track.

Certified vehicle compatibility and racing applications

This faithful reproduction accurately adapts to the mechanical configurations of the following models:

• Renault Clio 2 RS (Phase 1, Phase 2, Ragnotti, and specific engine setups)
• Renault Clio 2 X65 Cup (Official circuit racing versions)
• Renault Clio 2 GR N (Group N rally specifications)
• Renault Clio 3 X85 Cup (Specific cable-driven intake conversions and evolutions)

Technical frequently asked questions from drivers

Why choose this mechanical reproduction over a used alternative?

Finding a vintage factory unit in perfect working order is nearly impossible today. Used throttle bodies frequently suffer from excessive shaft play or warped housings, which skews engine management tuning and disrupts intake airflow consistency.

Is the throttle pedal responsiveness identical to the original?

The internal kinematics of this housing have been thoroughly studied to provide instant, linear response without any friction or stiff points. You will lose none of the dosing precision necessary when modulating throttle on corner exits or during aggressive stage restarts.

Are complementary parts required for a complete installation?

Depending on your intake configuration (original airbox, upgraded plenum, or Cup racing layout), specific connecting accessories, gaskets, or position sensors might be required to finalize the install. You will find all complementary products and peripheral parts listed at the very bottom of this product page.
