I have a 1990 mx5 mk1. I am about to change plugs and leads are 10 mm racing a good idea?

but nevertheless entirely correct.

Better off with a good used set of original 7mm leads. I see lots of sets and these work really well often for the the life of the car. They seem to perform better and more consistently, corrode less and last longer than anything else.

They will of course work, but won't make the car start better, perform better, drink less fuel or whatnot.

 

Originals were 7mm Yazakis, which tend to start to break down at 60k miles.. Mazda North America fitted 8mm NGK blues as replacements, not Yazakis.

 

Some Performance Lead seats, such as Racing Beat, can actually damage a coil pack doe to the way the connectors fit to the coil packs; they have two points of contact, and can short, burning the plastic.

 

I had a set of 8mm Magnacors, still have them in a box someplace. They were actually made too short for a 1.8. Currently have a cheapie set of 7mm yellow no brand leads from Autolinkuk. They do what it says on the time, and have been on over 5 years now. The key to any plug lead is how you fit it to the coil pack, and properly fitting to the sparkplug, properly twisting it to give a good water proof seal.

Agreed.

I once bought  a very expensive set of leads for my old Ford bitsa as part of a major service and it was awful with them.  I opened the bonnet at night with the engine running and could see the blue sparks going everywhere.  I immediately refitted the grotty old Ford leads and the problems (and sparks) vanished; the 'grotty' leads lasted another five years until I scrapped the car and sold the engine on to a Caterham. 

Halfrauds gave me my money back on the "top of the range" (huh!) Sparkrite leads.

Well I'll buck the response trend Eloisered and say I'm very happy with my 8.5mm Magnecor leads , my NGK Iridium plugs , my Pipercross drop in air filter coupled with plenty of Shell V Power fuel ... car runs like a dream and I'm happy to spend a few extra quid on pampering my little 27 year old beastie Wink
