What ht leads should i get for my rover mini sprite 1993 1.3 carb?

Ive seen more expensive ones but i dno if its worth it?

I want blue ones by the way

Can you give me links?

Thanks

A ht lead it a ht lead, unless its broken, there all just as good but silicone ones are also good. ull get them in blue too, and as for links i have none, but sure minispares can help you

I'd tend to agree with the above - As long as an HT lead is in good working order - it's as good as any other.

I disagree guys! Coloured ones definitely work better. Chrome would be even better still. lol

[Saxo-Fiesta-Mini]

the main things with HT leads are one resistance, two current flow and three insulation

you ideal want as little resitance as possible, currenlt flow u want a copper core idealy or even better twin core like split fire leads and insulation to stop interference on your radio and interference between the leads

this all in mind triple silcon leads like champion red 8mm leads are great as are lumension

and with split fire leads my favourite you get a lifetime gaurenty so if they stop workin ull get a new set awesome

as for the resitance of new split fire leads ill update on that one next time i visit mini sport

Red ones work the best!

No, we all know yellow ones with red ends do!,

you found any yet?

actualy i found out that fittin ones i had from work (just silocone ones) then trying a set of bummble be ones (black with a yellow stripe in it) it seemed better wether it was just me or not
(by the way for them that do not know bummble bee one is copper core)

Just a couple of minor points here....

You need to select a wire type to match your spark plugs. If you are running resistance spark plugs, you run low resistance or solid core wires. If you are running "regular" spark plugs, you use resistance wires... at least on the street. The resistance for the combined plug and wire should measure a few thousand Ohms.

The insulation on the wire by itself is not what suppresses noise. Insulation is there so you don't get a surprise when you touch the wire... and to keep the wire from shorting out to the engine/chassis. The resistance of the wires (combined with the plugs) is paramount to noise suppression. Some "modern" wires will use coiled metal conductors around a carbon filament core. These coiled wires are highly conductive but also create an inductance in the wires that will help suppress noise. This wire type is supposed to offer lower resistance for more spark energy while maintaining noise suppression. I have not seen any actual test results showing that this works... but that's what the sales literature says.

It can be a bit of a surprise when a spark plug lead actually fails. I've had it happen and was in disbelief that something so simple was responsible for the terrible misfire I was having.

I'm running with NGK BPR6ES spark plugs and red Lumenition ht leads from Mini Spares (part no. HV22) and my Mini is running like a dream.
