Genuine Renault New Bare Cylinder Head - K4M Engine Twingo 2 RS & R1 (Ref. 7701478763)

The cylinder head is one of the most vital components of your engine, housing the valves, camshaft, and combustion chambers. On a high-performance engine like the K4M in the Twingo 2 RS, its strength and integrity are essential for delivering power and reliability. Overheating, a timing belt failure, or a defective head gasket can cause irreversible damage (warping, cracks, etc.), compromising the entire engine. At Optimiz Access, experts in engines and genuine parts for sports vehicles since 2010, we know there's no room for compromise on such a critical part. We offer this genuine new bare Renault cylinder head, with manufacturer reference 7701478763, for a durable and safe repair.

What you lose by choosing a used or repaired cylinder head

When faced with a damaged cylinder head, some people try lower-cost solutions that can prove more expensive in the long run. Here's what you could lose by not choosing a new genuine cylinder head:

• The Reliability and Longevity of Your Engine

  A used cylinder head, even if inspected, has already undergone the stresses of its previous engine. It may have invisible warping, micro-cracks, or premature wear that will lead to a new head gasket failure, loss of compression, or overheating. With a new cylinder head, you start with a healthy foundation and significantly extend the lifespan of your K4M engine.

• Performance and Driving Pleasure

  A warped cylinder head or imperfect sealing results in a loss of power, excessive oil consumption, and inefficient combustion. These problems degrade the performance of your Twingo 2 RS on the road and on the track. By choosing a new genuine cylinder head, you ensure the heart of your engine operates at its optimal level.

• The Cost and Time of a New Breakdown

  The price of a used cylinder head or a risky repair is often offset by the risk of a new breakdown, which is much more expensive in terms of time and money. An engine with uncertain reliability can leave you stranded on the side of the road or force you to abandon a rally race. Don't risk a double repair.
