So I checked my manual and the periodic maintenance table indicates spark plug inspection every 12, 24 and 36 thousand kms.


Couldn't find any prompts to replace the plugs after a certain amount of kms/miles at first glance.


Furthermore, the NGK site is stating an average life of 60 and even 160 thousand kms for iridium plugs depending on type:


Type Service Life Benefits:
Nickel Alloy 20,000 - 40,000 kmsStandard style of spark Plug


Nickel Alloy
(V-Groove) 20,000 - 40,000 kms Improved ignitability due to sparking at periphery of the electrode


Platinum 0.8 mm dia. 100,000 kms Long service life and even better ignitability due to a small diameter centre electrode


Iridium 0.8 mm dia. 160,000 kms Extremely long service life. Same level of ignitability 0.8 mm dia.


Platinum Iridium IX 0.6 mm dia.60,000 kms Long service life. Same as 0.8 mm dia. of Platinum and extremely good ignitability characteristics. (Better than 0.8 mm dia. platinum or 0.8 mm dia. iridium)


I am in favour of changing parts for maintenance reasons instead of waiting for them to malfunction but is there any reason not to change the plugs every 60.000kms or more?


The only thing I can think of right now is low quality fuel


Is it a case of who is listening to whom in the end?

You can use any type or brand you like as long as their serial numbers match.


To be honest I don't remember what is stated on this subject about the euro edition right now so I will check later in the day

So, basically these Iridium spark plugs can definitely last for 16,000 miles instead of changing them for 8000 miles? I am sure dealer's repairshop will be happy to swap that with a low/ordinary plug & then resell mine for profit.

The service schedule for all Kwaks is plug replacement every 7.5K miles

You definitely don't need to replace them, unless you're worried about warranty!

Personality helps, but ATTITUDE is everything!

Well... my motorcycle is over four years old and even out of extended warranty that I had purchased when I bought the bike brand new.

So, still will it be an issue?

The bike runs perfectly fine... hence wondering if changing the sparkplug is necessary.... yes, future is always uncertain.

If you're doing the work yourself, I'd say, "Go for it!" It's a pain in the arse job if they don't come out easy tough...

If you're paying a dealer, you're gonna pay labour costs, but get peace of mind.

So...warranty isn't an issue and the bike is running fine; so basically it's up to you!

Question on the table is: What's worth more to you - Money in your pocket, but worry on your mind, or peace of mind and a hit on the wallet?

No, I am not going to do it myself, but give it to the Dealer.

Yes, peace of mind is more important than anything else, but wasting money on something that's not really reqd. or getting a lesser quality plug installed isn't something I am for too.

I hate to repeat this but when it comes to servicing trust no one, buy your own stuff and be present when they are fitted on your bike.


Your best bet will be to find a mechanic that you trust and stick with him.


No offense towards honest mechanics/dealerships as always.

its worth getting the plugs done because it usually highlights if there is corrosion on the stick coils which is a known issue on this bike (due to the location and water ingress), if the stick coils are corroded its 100% worth changing them because they can get stuck and be a massive hassle to remove.

Im talking from experience as I took my 08 er6f (ninja 650) in for service and the mechanic changed the plugs and suggested new stick coils. I stupidly was being a cheapskate and didnt go for it. The next service came up and the mechanic had to remove the rocker cover and all sorts to get the, now stuck, coils out which ended up costing more in the long run!
