HT leads...Magnecor?

[SI-PEN]

Hi Guys,

I replaced my HT leads last year with some from TVR Power, black in colour with grey plug ends. I think lots of companies supply these as the budget option. I didn't know that at the time and paid near on £80 for them.

Now a year on and 2,500 miles later I'm finding they are giving me trouble one by one, the leads look OK but have found they have developed a split in the insulation causing a mis-fire. I've changed two already over last 2 months but have again developed a very slight mis-fire.

I'm going to throw these away and buy some more expensive replacements but which should I go for...Magnecor?

I know TCS are doing some high performance ones with 10mm insulation and guaranteed 30,000 miles but just don't know!

What are you guys using?

Magnecor leads form ACT, only had them on for 6k though

I've had Magnecor for a couple of years now, and they seem to be in fine condition still.

Magnecor's are loveley.

make sure you use lots of those lead seperator clip thingies...to keep em apart and cover the leads touching the block with some plastic stuff, I used lots of wire ties and wire tidy accessories.

In any case, you will have most probably end the day with very sore fingers once you've replaced them. There's very little room to make sure they are clicked in right.

Si,

I bought a set of Magnecors from RPi Engineering last year for the Griff. Plug wires came with 4 x wire separators.

Wires were neatly marked and easy to install. My car felt more responsive afterwards (old wires were 8 years old...)

I had both types of TCS ones (std and high performance) on both of my Cerbs with no probs at all. I think that there were a few issues with the Magnecor ones but it turned out to be just a bad batch.

Just a word of warning, lead problems are normally caused by 1/the fitter using pliers to attach them and cutting the rubber boot/ manifold heat "cooking" the boot to death. this can apply to all lead sets.
the only magnecor leads with problems that i know of have suffered one of the above, to my knowledge there has never been a "bad batch" and i have supplied van loads, the original "bad batch" comment came from an alternative lead supplier.

It's just like the good old days

Group buy anyone?

Just remembered I have a set of Magnecour's in my Garage which I keep forgetting to Ebay - done about 1k miles.

Shall I just write you a blank check?

P.S. Are you just finding this stuff as your cars not in there at the moment? Wandering aimlessly out to the garage and looking at the empty space?

Hows it going? When's it coming back?

Yea i got a set ( Blue) going begging, with coils! Thought i was going to use them, but the Chevy stuff is neater in my application.

I was told by Fernies that the leads should be replaced every service, and hence not worth paying more for uprated ones.

[brummiewedge]

Why?......

[SI-PEN]

I'm thinking...Magnecor leads are 8mm thick, TCS have some that are 10mm thick. Perhaps I already have my answer!

The heat generated in the engine bay just destroys the leads and they break down. I was told that it wasn't worth paying extra for better leads. Better to just replace with the norms every service.

Had two blue magnacors break down on the Cerb recently - both less than a year old. Heat from e/manifolds heated and cracked the insulation at the plug end and caused arcing to the block. Replaced f.o.c. by Austec. Need to look at some form of insulation in that vulnerable area!

[SI-PEN]

Thanks for all your info on this Guys, I did actually order the 10mm leads from Track Car Solutions.

The leads arrived today and they are bl**dy huge, if you have a problem with heat destroying your leads then get a set of these. They are like JUMBO versions of the originals I got from TVR Power last year.

They even match the colour of my car, that'll be the faster colour which you all know to be Blue!!!

I had the standard ones on originally. They were changed to magnecor's on a sevice due to a slight misfire, so they were changed as a possible cause. 18 months later, on another service, at another garage, they were changed back to the standard ones even though I didnt notice anything wrong.
