Not sure £100 + Best give your local Dealer a ring, Their price can vary from dealer to dealer
All these can be purchased from a good Motor factors with considerable savings. But try a Renault dealer first as a price comparison.
Ensure you fit NGK plugs of the correct type as some say the wrong plugs are a contributary factor in coil failure.
Keep us posted on what Renault charge
Edit : Also ask at a Renault dealer for a discount most will if asked.
An ignition coil (also called a spark coil) is an induction coil in an automobile's ignition system which transforms a storage battery's 12 volts to the thousands of volts needed to spark the spark plugs.
This specific form of the autotransformer, together with the contact breaker, converts low voltage from a battery into the high voltage required by spark plugs in an internal combustion engine.
In older vehicles a single (large) coil would serve all the spark plugs via the ignition distributor.
In modern systems, the distributor is omitted and ignition is instead electronically controlled. Much smaller coils are used with one coil for each spark plug or one coil serving two spark plugs (so two coils in a four-cylinder car). These coils may be remote-mounted or they may be placed on top of the spark plug (coil-on-plug or Direct Ignition). Where one coil serves two spark plugs (in two cylinders), it is through the "wasted spark" system. In this arrangement the coil generates two sparks per cycle to both the cylinders. The fuel in the cylinder that is nearing the end of its compression stroke is ignited, whereas the spark in its companion that is nearing the end of its exhaust stroke has no effect. The wasted spark system is more reliable than a single coil system with a distributor and cheaper than coil-on-plug.
Where the coils are remote mounted they may all be contained in a single moulded block with multiple high-tension terminals. This is commonly called a coil-pack.

Good point on asking for a discount, Ottoman. I rang my local Nissan dealer to find the maximum possible price I would have to pay for a clutch kit for my Micra - answer £105. When I said I was going to ring round he said he could do a discount - new price £70. Save £35 just by asking!
Eventually got it from Jayar factors for £40. Someone in the trade probably would have got a discount on that.
