Are you ignorant????
by the looks of your post you are...
first off just as you, and I, contour se driver is entitled to his opinion... he shouldnt be told to "stfu" because he disagrees with you.
yes for our cars the denso spark plugs are not the answer due to the ignition system, because of the way our cars ignition fires they would wear prematurly
however on cars with a more standardized ignition the denso's have proven to be very, very good plugs... they last longer then platinum and the seem to be more stable at higher combustions temps. so for the right car they do have an advantage. as for hp gains? because the can provide a more stable spark in certain motors they will show a large improvement over standard plugs
either way, state your opinion, and dont belittle others for theirs
