Hello,just fitted some new
and for the price they are the dogs.
Made by MTL and cheapest sold on
at £35.00 for 4.
I payed for them yesterday afternoon and here this morning (first class next day)included.
What a difference ,previously I had Beru,supposedly good,these are as good if not better,time will tell.
Beru were 6 months old and playing up.
I know a lot of forum members are staunch Renault supporters and believe Renault only spares are needed but I dont think its true exception bieng with spark plugs.
I will let you all know how they perform later.
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.

Only had them a day actually and said they were the dogs ,no more.
You implied the depletive.
I can tell if performance is improved,seems then that you are not able to,its experience you see.
So far so good and as I always say ,time will tell?
At £35.00 for 4 against up to £70ish each,gotta be be good.
I try to help,leave it up to you mods to put it in correct catergory.either user reviews,electronics,engines or tuning.
Not sure where to post,but must agree cant go too wrong at around £8.00 each.
