Iridium Spark Plugs for Glee

[bosnjo]

Is there anybody on this forum who changed spark plugs on his Glee (mine is 2012) to iridium ones and is hapy with them?
If yes, can you please give me the model and part number (NGK, Denso?).

What interval do you recommend for first change (miles or km's)? I know those manufacturer recommendations on intervals are always way too short for all parts, so I'm asking about opinions based on experience.

Thanks

It has iridium plugs as standard.

The standard plug is NGK CR8EIA-9, this is an iridium plug.

[bosnjo]

Service manual says "NGK CR8EIA-9" or "DENSO IU24D".

As Jacko says.
Plugs on mine are Denso iridium they came as standard, didn't change them at the 7500 service interval as no need to,   may look at changing them when doing the shims at 14500 but only if they are needed, both manufacturers claim good mileage from them  

[greywolf]

Since the bike comes with Iridiums, disregard the replacement info in the manual. That interval was crazy even for standard plugs which can do 20,000 miles with no problem. Glee stock plugs are good for at least 50,000 miles.

I'm sure replacing the iridium plugs on my old Alfa 155 was on the 100k service: it's a joke replacing them when Suzuki say to.  

Mind you, there were 8 & it was shrapnel change from £100....

Agreed, inspect and evaluate  

[Jacko]

Throwing iridium plugs away at 7,500 is like pouring a pint of ale away after one mouthful.

The Suzuki workshop manual, for some reason, specifies non-iridium plugs as replacements, at 7,500. This is madness, the plugs they will put in haven't got as much life in them as the ones they're replacing, and 'binning' (yeah right).

[bosnjo]

OK,
thanks blokes, I knew that interval on plugs is crazy. I was as well not to change them for a looooong miles yet. I will inspect them, as my Glee was purchased 2nd hand.
I know I have read somewhere, before getting my Glee, that there was some mess on dealers' info on plugs, so people would go on scheduled service, plugs changed and then all the mess started. Later was discovered it was bad info on plugs, as plugs were being changed to different type. I know it was on DL650 but I don't remember if it was Wee or Glee.
As I now have Suzuki Service Manual, I was just asking this question to make sure with you blokes that the wrong info was not in this service manual. But you're all saying the same reference as in this manual, so I see I can trust it. No, I was not about to change plugs, just to inspect them. I'm ex-mechanic myself (car mechanic) and I know a lot about "scheduled maintenance" and "recommended intervals". So, warranty is to end when bike reaches 12000 km's (recomended interval) so no need to worry about dealer anymore. All of the service will be done by myself using OEM parts. I'm not even sure I'll change brake fluid and coolant or wait one more year (until my Glee is 3 years old). Will see about that one, yet to decide (opinions?).
Thanks again

Hmmm, my workshop manual (99500-36220-03E) recommends iridium ones on all needed intervals. Strange!

[Jacko]

Apparently it was scheduled for change when the error was discovered. It was one of us on here that had all the trouble, think it was UKVstrom, they tracked it down to the wrong plugs being specified in the Suzuki workshop manual and Suzuki were informed.

I've found it, epic thread.

My original NGK (standard) plugs did nearly 30k miles with no enlargeing of the gap, no visable eroshion of electrode. I had iridium plugs standing by and so will see the bike out.

[greywolf]

There are a number of odd items in the manuals. Some were causes by using old materials as boiler plates. http://www.stromtrooper.com/general-v-s ... ments.html

Yep, that's what the dealer told me. They fitted the service manual spec plugs & my bike ran like it was fuel starved at constant throttle... Only took 2 months to sort out  <!-- s:shrug: --><!-- s:shrug: -->

Thanks for the info on plugs, at 17,500 miles now, plugs were changed at 7,500 miles, hope they didn't throw away the iridiums and put in standard plugs,
is it really necessary to inspect the valve clearances at 14.500 miles? what's the experience of those that have done it? my bike isn't listed for recall.
just that the mpg has gone to hell lately and I'm trying to figure out why.

[SuzukiSte]

Mine are Denso iridium they came as standard also AL2 Glee.

[vstroman]

Just been on to the Suzuki dealers who did the 7,500 mile service, they replaced the original plugs with NGK CR8E standard type plugs,
I mean ffs how stupid are these people? anyway according to Greywolf these standard type plugs are good for at least 20000 miles so they will do me for another 10,000 miles anyway.

[Ianmc]

Did they charge you for iridium plugs?They are a lot more expensive that CR8E,s.I am sure my CR8E plugs were not changed at 7500mls.When I took them out at 15000mls.the gap was 50thou.ish.but they were charged for!

[vstroman]

Hi Ian, they would have changed the original fitment iridum plugs for regular plugs according to them, I must remove one of the plugs and check if they did actually change them, they might have charged for them but never done it, I'd prefer if they hadn't now, but anyway it will be easy enough to find out,
I figured out the sudden change in mpg, when I was fitting an optimate lead to the battery,the battery was disconnected temporarily and this caused the readout to revert to mpg US, I hadn't been on the bike alot since so I was baffled, I didn't even know the European spec dash had the option to show US mpg,but there you go,live and learn.no Americanism filter there
I also quizzed them on the 11,000 mile service,the air filter is down on the service book to be replaced at this stage, but they say they inspected it and it was OK? likely story me thinks,can't see them going to the bother of removing the tank to inspect the filter, I think if they had gone to that much bother they'd have slapped a genuine part Suzuki air filter in there, I think all they do is change the oil and filter and print out an invoice for £200 or so.
You can tell I haven't much confidence in these main dealers service depts.

[UK_Vstrom650]

I was once told by a dealer they don't need to remove the tank to inspect the filter or change the plugs...

This is why I want to do my valve clearance inspection myself even though the missus will moan at me for not paying someone to do it.
