Stuttering and Ignition leads - which ones?

Due to some intermittent stuttering from my MG TF160 on acceleration between 1250-1750 rpm (only experienced when accelerator is applied >1/2 way), a bit of research has led me to thinking about replacing the HT leads and/or coil packs (fuel/air filter replaced recently).



I can get a genuine pair of coil packs from ebay for £68, or £35.99 for a single one but I'm a bit lost with the leads.



Im currently looking at the Magnecor ones, but I'm unsure which ones are more suitable. Both of these below are recommended for the 160 (vvc)

which are 8mm and blue

and these are 8.5mm and red



Any help would be appreciated, including any alternative products which might be cheaper or more recommended.



Thanks
