are the denso spark plugs worth it? and if i do get the denso ik16s what kind of wires should i buy? thanks

 

nope,your NGK stock sparkplugs and wires is the way to go

 

hmm im not sure but my opinion,
if your engine dont need the extra spark...
(ex: bone stock engines or just bolt on stuff)
wouldnt the extra power do more harm than good to your car?

 

I'd wait on upgrading the spark plugs, and wires. Same with fuel injectors.

 

I ran Denso Iridiums in my Accord for 30k (life of the plugs) and swapped for NGK Iridium a few months ago (Cheaper and should last a bit longer). Both offered a modest improvement in fuel economy and a definate smoother idle, verified by putting my NGK's that were only used for 10k miles back in between changes. Changing wires on a stock setup won't do anything unless your current wires are worn out, so save your money unless you want the looks.

Why not? The standard NGK plugs and standard Denso plugs are what they call out in the service manual. So if he is refering to the standard Denso plugs, why would the standard NGK plugs be so much better? Or is NGK your personal preference? I have the standard Denso plugs, haven't put them in yet, but I don't feel there will be any problems.

 

yea thats what i heard from my friend, wells he has an 86 swapped a jap engine in and got some denso, he said " it's suppose to help the engine cool" something like that. but it is big $ on them ik16 and wires sheSh.

 

Are you talking about Denso Standard plugs or are you talking about Denso Iridium plugs?

 

i'm talking about denso iridiums

it's not worth it.

 

everyony one accordv6.com seems to swear by the iridums.

 

The Iridiums are good, but on a stock set-up they are not worth the cost. Before, I though you were refering to the Standard plugs not the Iridiums. Just stick with what the Helms calls out:
NGK - ZFR5F-11
Denso - KJ16CR-L11

 

honestly the prices are coming down on these that you can pick them up for under $50 so it almost makes it worth it to give them a try. you should be able to keep the iridiums at least 2x longer than coppers. i would like to see real "independent" dyno proof though. i'm getting dyno tuning done soon, i'm very tempted to try them v. my ngk coppers.

as for V6 owners, they use platinums anyways which cost about the same so it's worth it for them. also since the the 3 plugs are a bitch to change, extended intervals of iridiums is a benefit than going with coppers.

 

Denso Iridium IK16, which is the correct temp plug for all of the 6th gen Accords, are supposed to last only 30k miles. These plugs are designed for performance (small, but still gains), so service life was traded for performance. NGK makes the "Iridum IX" which I'm now using after having the Denso's for 30 k miles. They are designed to last longer than the Densos due to their larger electrode, but won't last nearly as long at the platinum plugs are designed. I paid somewhere around $30 shipped for my NGK Iridium through clubplug.net, so I think it's worth a try.

 

yea i'ma give it a try yes the denso iridiums ik16s, and what kind of wires(8mm) should i get? thanx

 

If you're using platinum spark plugs, then iridium or copper plugs are good choices to use when your platinum spark plugs go bad or wear out. If they're not worn out, it'd be hard for you to feel (butt dyno) the possible 1-3 HP increase. Of course, the smoother idle and better gas mileage may be felt more immediately, but it makes better sense to get them if your plugs wear out.

And the iridium plugs should make more HP than the coppers. That's purely from the chemical properties of iridium vs. copper. Of course, I don't think iridium plugs will have the same size electrode tip as the copper plugs, but that's another story.

You know what? The 7th gen. Accords (not sure if both I4 and V6) use iridium plugs as standard. That tells you something, doesn't it? It means the technology is time-proven and effective. If people are interested in saving money, they may want to get Honda spark plugs for the 7th gen. Accords and use them if they're cheaper than buying retail Denso or NGK. I'm not sure on the heat range for the 7th gen. Accords but I'm guessing they're IK20.

 

Since replacement platinum plugs are nearly as expensive as iridium plugs, the better choice is to iridium or copper plugs. Copper has the best performance/$ but iridium is the absolute best performance proven by people's dyno runs. Platinum has the best life/$, so if you value longevity over anything, platinum is your answer.

 

so what would be better to try ngk or denso iridiums. i know the denso have a smaller electrode which supposedly makes more power at the expense of longevity. however the ngk ones are cheaper and should last longer.

 

so if i get the iridiums i just keep my stock wires? or is it recommended to get new wires (8mm)? thanx

 

Um, silveraccord01, do you see any ignition wires around your engine? You shouldn't since 00-02 V6's have direct ignition. So you have no need to replace the wires since there aren't any for those year engines.

em..yeah 00-02 v6 have the plastic clips instead of wires

 

denso iridium sucks, mine either broke in half or got loose....dont get them NGK is better

 

Got them loose? You must've installed them wrong. Fouled tips are one thing but the whole plugs breaking in half and becoming loose? You must've put in wrong plugs for your engine or did a bad job installing them. I've never heard of Denso iridium's do that before and it just sounds ludicrous that it'd break in half.

The last time i heard that a spark plug snapped to 2 piece is when the motor blew from spraying or overboosted.
