Replacing ignition lead set

Re-united with the Jimny after another stint back in Bavaria and now time to replace the ignition cable system (4 x leads plus the 2 components that the leads attach to.). As you see from my description, I venture yet again into unknown territory, but watching a few Jimny youtube videos it seems a simple case of plug and play.

My questions:

• are there any lurking hidden unknowns I must look out for before doing this?
• Is it really a case of simply unplug the one set and replace with the second set?

Vielen Dank!

Unbolt plastic cover, unplug and unbolt coil packs, remove old ones, fit new ones.  No difficulty.  The cost is high if you buy new ones, though - you can get good used ones for about £40 a set, not necessarily from a Jimny (the Swift used the M13A engine too,).

Many thanks - yes the cost was high (I got a set in Germany that cost more than GBP40, a client just paid me haha), so on your thumbs up confirming my initial impression, I will do this either this week or Saturday. Looks simple... ... if it fails this will turn into a loooong thread!

Try to look into the spark plug recesses when you do it, just in case there is an oil leak or a plug with failed sealing.  It's quite common for the lower part of the HT connector and the ceramic part of the plug just above the nut to be brown (corona stain).  Long brown streaks up the ceramic plug insulator might mean the sealing has failed and compression is leaking, though. I had this on a set of NGKs years ago.

It looks like you can get Hella or Denso around £30 - £40, original Suzuki are very expensive.

A search shows up other brands, most of which I have never heard of and some not much cheaper than the Hella or Denso, so I would suggest going with a brand you know as some of the [not so] cheap ones might fail after a short period of time.

I bought Beru for my other car from GSF, they were a bargain, about 1/4 of the price of the other good brands (Bosch, etc) and since that car needed 6 coils/leads it was a massive saving, it's best to look round GSF, EuroCarPart and the other dealers to see what offers they have on. Beru is right up there with the best.

I think those prices are just for the HT leads.  The two coil packs themselves are very expensive and are more likely to give trouble than the leads.  Plus you can only fix two cylinders by changing just the leads!
