What plugs do VFRs like?

I am the second owner of a great 5th gen 2000 VFR and am about to change my spark plugs. I would like to know what you guys have found to work the best in your VFRs.

 

I just finished my 30,000 mile maintainance a month or so ago and I installed NGK Iridium CR9EHIX-9 6216, and I'm really impressed. The spark plugs are the only replacement parts and I was impressed with how sharp the engine feels. Of course the old plugs had 15,000 miles on them so you have to consider that too. But I'm happy.:smile:

 

Not sure about the VFR specifically, but Japanese equipment seems to really like NGK or Denso. Would I put autolite plugs in the VFR? Probably not... :biggrin:

 

I was thinking about the NGK plugs. The few places I have called for prices have offered up NGK Iridium for about 17$/ea and NGK something? for 19$/ea. A couple of places suggested Champion copper at 13/ea and Champion power? 9$/ea.

With out actually trying them all I guess I would lean toward the most expensive. They usually work the best but hey, thats why I'm asking you guys. Are the 100$ set of plugs that much better than the 50$ set of plugs? Hmmmmm?

 

I paid a touch over $36 including shipping for 4 of the NGK Iridium plugs. I thought that was too high, but I wanted to try the Iridium. There is no way I would pay more than that for plugs.

 

NGK iridium plugs work best in my year 2000 model.

 

I have always owned Japanese bikes and have always used NGK. Can't go wrong with them. I have standard NGK's in my '98. From what I have read, the iridium may or may not give any performance help (not siginficant), but they should last longer. Considering how much of a PITA it is to change the plugs, I wish I would have spent the extra few bucks on the iridiums. Next time they will be going in.

 

I used Sparkplugs, don't use Glowplugs as I've heard people having problems with them.

Just joking +1 on the NGK Iridium CR9EHIX-9's. My 5th gen loves them.

 

Do they come with the cool sticker? That gives you 5 extra HP, you know.
I should prolly change my plugs this summer too.

 

Thanks for the input. I guess I will try the NGK iridiums. Can anyone recommend a site for low price plugs?

 

I got mine off Ebay. I can supply you with the vendor if you want.

 

Not necessarily the lowest price but great service and fast shipping is Summit Racing - High Performance Car and Truck Parts | 800-230-3030 Of course you need yours to go Canada so that could cost more.

 

Is there a certain size or part number for a vfr? I need to change mine too.

And what about the Denso iridiums? Same as NGK?

 

I have NGK in all my Honda and Acura stuff.
Denis kirk has been where I have been shopping very quick for me.
I will pay for good customer service and have been very impressed with them.

 

Howdy All, My vote goes for the iridiums, Just a word of caution,they dont recommend
that you gap these plugs,supposed to just take them from the box and put them in.
The center conductor is about the diameter of a needle and is pretty fragile,I always eye ball them and if they look out of spec,I VERY CAREFULLY without touching the center conductor move the gap arm. I would never use a metal feeler gauge or wire gauge to gap them ,I generally use a piece of plastic that is close to the gapping spec. And as
the other guys stated their claim to fame is they last longer. eddie

 

I just put in the NGK iridiums yesterday. People were talking about these outrageous prices for them. I got them from a local shop for $8 a piece. Also, it only took me about 40 minutes to change them all. I was a little nervous when people were saying it took them 2-3 hours! Those front two are fun! Whoa.

 

Well I went to my local dealer yesterday and paid too much for plugs(just the recommended Honda NGK, not Iridium) and an air filter. It was such a nice day out and I had the whole day free so when they had the stuff in stock I just bit the bullet and got it. I have done so little maintenance on the bike since I got it. I really want to dig in to it this spring and get familiar with it. I took off the side panels, the half cowl and the rear plastic so I could inspect the rectifier and wiring as I replaced the air filter and plugs. The rear two were ok but the two in front were a bit of a concern because of the road dirt around the top of the plugs. I didn't have compressed air and just had to brush the dirt away as best I could. Anyway, everything is back together and she sounds fine. I am going on a big trip in June so I want to be ready. Next items of maintenance on my list include replacing brake fluid(going to be tricky I know), clutch fluid and fork oil. I have not checked for and threads on these. Hopefully there are some helpful info.
Thanks for the info on the plugs all. Cheers.

 

I pulled the NGK-R's out of kristins gen 3 and they were perfect. we got the bike beginning of last year and I think the dealer installed them then, slightly tan color and no fouling at all. ran them again this year. I installed the Iridium in my 04 FZ1 this year & it runs fine. maybe marginally better but the NGK-R's in that bike were nasty fouled, typical inline 4 R-1 motor i guess.

 

+1 on not having to change them every 12K or whatever. The plugs I took out were fine, but since I bought the bike used, I had no idea of when they were changed last.
