Hey Vanquish... how feel your sentra changed new spark plug?? have feel it more power then before???
Sadly no... No changes in power delivery... I drove an Indon friend to LCCT yesterday afternoon so I have a chance to test out the new plugs... While on the highway, at certain RPM (around 2,800 to 3,000 rpm at 120+km/h), the engine choked and white smokes starting billowing out of the exhaust, I press on the pedal a bit more, then no more smokes, as I let it go back down to 2,800+ rpm, the engine starts to choke again and white smokes started billowing out again...

And white smokes would come out at 2,500 rpm as well... Lots of it, actually...

Funny thing is, normal driving (in speed less than 90km/h, there's no smoke at all...
I suspect something is wrong with the ULTRA plug cables... This morning, I changed back to the OEM cables to check if there's any similar problems, haven't notice anything yet though... Maybe after work I'll go on the LDP and check...
