Had an email from Larkspeed advertising these spark plugs, apparently they can give up to 12 bhp!!! Anyone ever tried them or heard of them??? Just wondering!!!
interesting, but remember its a nissan engine based result.
I guess we all know the stories how nissan skyline turbo engines are easily tuned
You change sparks... bamm 10BHP more and so one.
They did pick 350Z for a reason, trust me
No harm in that Every one will say stay with NGK since this is OEM best
I'm a bit of a rough agent myself I take what other tested and always try something different in adition
Brisk Premium LGS worked for me.
One thing for sure, no 10BHP gain from just a spark plug
