Why spend 200% or 300% or 400% or more for a product that the manufacturer reccomends when you can get a replacement that works just as well for a fraction of the cost :?: I switched to Bosch Super #7557 for less than half the price of NGK and cannot tell any difference one way or the other. I just thought of something else. My owners manual says NGK or Denso. Does anyone use Denso plugs?sjvanepps said:Nothing invites more opinions, anecdotal stories, and "BS" among bikers, snowmobilers, or car buffs etc, than oil, filters, and SPARK PLUGS. The discussion about all three rages on, and probably will as long as there are engines that use them.
Consider this. Honda (and all the others) spend many $$$$$$$$ and a gazillion hours of dyno and road testing time, in conjunction with their spark plug vendor, to come up with the best plug for the intended use of any particular engine. Just because another brand of plug is called "equivalent" doesn't mean that it is the same. My years of racing and building racing engines have shown that there can be, and usually are, differences in heat range, that over time, can be problematic, although rarely ever serious, except in the case of a very highly tuned engine.
Honda uses NGK plugs. When I am due to change plugs (long time away) I will use NGK plugs, and I don't care what they cost. I may elect to use a better style, such as iridium instead of platinum or whatever is the best at that time, but they will be NGK for my 1800. My oil and filters will also be Honda, at least until the warranty expires.
Why in the world would I "cheap out" on the cost of spark plugs that run many thousands of miles anyway, on a machine that cost me many thousands of $$$$$$$? I don't get it. :roll:
Just my $.02. Rock On! :chat:
