Magnecor or Top Gun Ignition Leads

[RG.net]

i just got some OBX-R leads for my mx today, these are 10.5 mm thick and are alot better then stock, not sure on comparison to magnacore and top gun, but i have heard that magnacore tend to break. i got these plugs for $60 from us ebay.

10.5mm

i've got the blue Top Gun 8.8mm (i think) on my BPD engine, seem rather good & just still fit into thw holding clips.

No problems with my mangacores

I've had them 5 years

I am not sure why you need to use anything but a good quality std lead for a stock engine. Shelling out extra cash is not likely to give you any benefit.

The aftermarket ones are, more often than not, cheaper than genuine Mazda leads. You can get standard replacement from Supercheap or Repco; but then you have to ask yourself if you are still using a "good quality" lead.

I think I have the 7mm magnicor leads (they are blue). I have had them for a couple of years no problems.

How many years do they last anyway???

[Mr Morlock]

How often do you replace spark plug leads? For a standard petrol car being dríven \"normally\" you probably never replace them. Where leads can show deterioration is for lpg installations- I had a Disco on gas and the popping and banging was fixed with a lead change. The Top Gun leads were made in Aust some years ago and I saw two of the plants that did them. Quality was good. Not sure where they are sourced now. But Boags is right- it is not always easy to know what is good and what is not.

At a very very rough guess, the standard leads could be changed every 50-80,000 kms to avoid any issues

my stock leads were buggered on 136---kms (unless changed by previous owner) but they were starting to fall apart i.e rubber bottom came off, and plastic piece also came off, car ran poor and liked to idle jump whislt having indicators on and turning, didnt like starting up when hot (quick run in to the shops) i put these obx leads in, and that has all changed. as for oem quality, it fell apart in the end lets see how long these ones last.

I've got Magnecor Blue leads. I used to run on three cylinders every now and then as they slowly wriggled their way free from the coil pack. Now i've got them cable tied down and all is well.

The original Magnecore design for the NB8B was rubbish. The lead would slide out through the boot on the spark plug side not clipping onto the plug and the boot itself would'nt seal onto the valve cover properly, but would weld itself to the spark plug making it next to impossible to remove. I've been told they have redesigned them though. I got a refund and went back to factory leads. Click, click, done for another 90,000km. Everything fits perfectly and works like it's supposed to.

Have used 8.8 top gun spiral wire leads now for the last three years.
never an issue, run a Bosch 4 point plug with them and it seams to be a good combo!

Yeah I did notice it takes abit of force and effort to remove magnecore the leads from the plugs. I think its di electric grease/silicone makes it a bit easier.
