Hi fiat mates,

It´s been few months that my car has been annoying, that is I have bought TWO NEW SETS!! of bosch spark plug wires, and the sparks just blow throught the legs which go on the spark plugs:bang:.

Does anyone have a good idea what I should do?, Are Bosch just **** or what?, do you know of any reliable manufactures?

Any advise would be great.

Thanks.

How old are the plugs? and resistor type is probably not a good idea.

R type is essential. Otherwise the ECU will pick up the interference and you'll get all kinds of issues. Resistor plugs wrere introduced specifically for EFI.

The "legs"? I'm a bit puzzled. If the clip holding the cables is metal, there's a chance it's abrading its way through the cables. Try avoiding that or using a plastic clip.

The Bosch ones are nothing special, just cheap replacement ones, but I'd like to see a pic before recommending anything more expensive.

thanks for quick replies guys

The spark plugs are almost new, I was fixing now and managed to seal the legs with duck tape and silicon spray for temporary fix, and used 3 of the old ones. But what are R types?.

And btw the old ones were not original, the heads on the legs were modified by cutting them so they would fit in the holes, by previous owner, and the wires are much longer than they´re suppose to

But I still need good reliable ones, but the legs that i was talking about go on the spark plugs, excuse my lack in english I don´t know how to explain properly, but I will put picture soon of the bosch wires.

R = resistor. It's clear -- at least -- in the NGK marking: B8EPR (for example).

My guess is that the leads may be for the wrong model and thus are not seating correctly on the plug tops...........

I only managed to take these two before the battery in camera was empty, this was the worst damaged wire. Two others have smaller damage.

Most likely a combination of the wrong ear plugs/moby combination or the Armani mouse mat melted the silicone.

That Was help full wasn't it

The spark energy will take the easiest route. If the connection to the plug is loose that might be enough to cause it to track elsewhere.
