Don't risk your engine's health with a cracked component. This Genuine Renault Exhaust Manifold (Reference 140041KC1A) is the vital part required to ensure the seal and performance of your Renault Clio 4 RS. Specifically designed for turbocharger mounting, it guarantees optimal gas flow without pressure loss. Avoid exhaust leaks that degrade your driving experience and the longevity of your turbo.
Ignoring a crack or deformation on your original exhaust manifold means accepting immediate power loss and a significant risk of engine failure. On a Clio 4 RS, the manifold undergoes extreme thermal stress. By keeping a fatigued part, you expose yourself to exhaust leaks, increased fuel consumption, and ultimately, the destruction of your turbocharger blades.
Unlike inferior quality aftermarket copies, this cast iron manifold from the original manufacturer ensures perfect flatness. This is the assurance of an absolute seal between the cylinder head and the turbocharger. Failing to choose this part risks an unpleasant engine whistling sound and fault codes (Check Engine) related to boost pressure.

The smell of exhaust fumes in the cabin, a "ticking" noise when cold, or a drop in turbo responsiveness are clear signs it is time to replace your manifold.
Absolutely. Fitting a new manifold on old gaskets is a guarantee of an immediate leak. You can find all complementary products, such as the manifold gasket and studs, at the bottom of this product page.
