which new ignition leads

[SeanOB]

Spotted a small nick in my #6 HT lead of my facelift 325i sedan, and would like to replace the whole batch.

Recently I have had a missfire on occasion, despite replacing distributor cap and rotor, C191 plug, ignition coil, spark plugs & refurbed the injectors. Seems like a logical next step to replace the visibly damaged HT lead at least, but I would really prefer to get the full set for peace of mind.

I know it is recommended to get them from the dealer, but I cannot part with the £300, and have an MOT next month.

So my question is, what are the best aftermarket options, or is there a product out there that is actually the same thing we would get from the factory.

For example, are these likely exactly the same thing as part#12121720529

I know, red HT leads do not make your car faster.

I Bought the proper Bosch kit, really great quality - after I found a burnt out resistor in one of my old cables which caused an intermittent miss ( the resistor is inside the socket of each plug cable at the plug end )

Also comes all ready to "plug and play" with the cable cover.

ahhh perfect, Thanks Paul that sounds ideal.

Does that link above look like the right Bosch kit, it doesn't exactly describe a whole lot.

in case anyone spots this when searching to resolve a similar problem, I have bought the leads from the link https://www.onlinecarparts.co.uk/bosch-1160980.html

They are the correct ones, fit them yesterday. The wires are not labelled, so you will have to unclip the plastic cover and check everyone. I recommend that store, cheaper than CarParts4Less at times, even with the shipping from Germany.

I do find the spark plug connection ends are bigger, as in the rubber boot itself touches the head when connecting to the spark plug. Really hoping these don't melt away or cause more glitches due to heat.
