We supply them to a few of the MG-R based motorsport teams - no issues reported, and there's a lot of highly strung engines in and amongst them (a lot of K Series 1.8T, a supercharged ZS etc).
Apart from the platinum tip, our plugs are identical to the originals. We went with these for the good reason above, and not because of price. 
I've also run them in every K Series and KV6 car I've owned over the last 5 years - no issues to report and the KV6 ZS I had them fitted to made 195.5BHP on the dyno with a light remap.  |
Which plugs are you referring to, the K16PR-U11 plugs or NLP100290 plugs ?
