Just go to the Denso site (densoiridium.com) and call the number on the Contact us section. Their exclusive distributor sells them for like $5-$7 bucks. Cheap! Oh yeah...sorry if I am undercutting the sponsors. I just want to tell people that there is a better price out there. Latez!

 

sorry, this is incorrect information. please research before slamming prices that sponsors of this site.

 

My gawd.. come on people... These plugs aren't going to give you ANY better power..and if you idle better... try a $.95 cent plug instead-- it'll idle better too than your old plug.

IMHO: Snake oil or Honda would have put them in by default.

My bad for slammin...I just checked my receipt and they go for $11.20 a piece. I'm sure jpotts can hook it up much cheaper with his quote of $9. Latez!

 

I thought platinum plugs were about longevity, not power?

As an electical engineer I can't imagine any significant effect on spark characteristics because of electrode material. It's to do with the energy dissipated and the gap.

The shape of the electrode could have some bearing because with the right shape you can build up greater field strength at the tip before discharge, but I don't think it would be significant here. You'd be better off to just increase the gap.

<<Thats a darn good question....why didnt they?>>

(Why not s2k OEM) Probably a cost / benefit thing. Don't forget that the car has many long service intervals such as for 100 K plugs and valve train clearances. Replacing the plugs, using better plugs, adjusting the valves more often than the bare minimum marketing oriented spec may make some sense. It's worth trying out. Small changes are very tough to dyno with repeatability. And most folks dyno only at wide open throttle. Sometimes things can be better or worse than stock at part throttle. Most street driving is at part throttle.

You could also ask why the car does not come with a true CAI or washable long life low restriction air filter.

>>>You'd be better off to just increase the gap.<<<

Oh yes! Lots of cars benefit from widening the gap. I don't know whether this would help the s2K or not but if the stock plugs can go 100 k then there is certainly some ignition capacity available to handle such a tweak. Suppose the car benefited from an extra 0.010 or 0.015 inches....in that case it might need plug changes every 50,000 miles or whatever. Shrug. Remember that a rich mixture, such as at WOT is EZ to light off compared to a leaner mixture. Fewer mixture moleclules in/near the gap for one thing. This means that in some cases, the wide gap improvements could be more noticeable at part and transitional throttle.

I'm always amazed at how few people try out such simple, cheap tweaks. One guy emailed me about suggesting a good mechanic to handle a spark plug gap "mod"!!! Uh, if your mechanic can't gap a plug get outta there!!

if you get super street, september 2001 edition there's an ad about denso plugs on page 41 with dyno results.
