11-14 Triumph Rocket III Roadster NGK Iridium IX Spark

[Lemieuxfan]

wanted to pass on the following information now i know many of you are probably running these in yours with no issues and have done mods again with no issues but wanted to pass on the following intel. Bike is ready for pickup approx. 599 on her long overdue 20k service at 23,600 miles brought two jugs of Motul 7100 10-40w no issue there along with 6 of these plugs. Well- called local dealership and they mentioned they were specifically told by Triumph to NOT install these as they can/tend to run too hot for the pistons.

Standing down on these plugs; engine is already incredibly powerful law of diminishing returns is upon us folks.. we already have the strongest motor of any bike do we really need to overlymod it resulting in issues down the road.

I think not the only thing i wish is maybe it sounded like a harley but that isn't going to happen even with mods and money invested

I trudge on

Used the Iridium plugs years ago and never noticed one bit of difference never used them again, some people are perfectly happy with the bike staying stock and nothing wrong with that, now having the strongest engine of any bike hmmmmmmmmmm

Can you post the plug code up here?

DPR7EA9 were the factory plugs in my 2010 Roadster.
I believe Rockets used to come with 8's (a colder plug) but they changed to 7's after a couple years (by Sept 07 at least).
Not sure what Triumph's problem is with iridium plugs so long as they are 7's too (DPR7EIX-9) and not 6's for example which would be hotter plugs.

Link don't work for me bro, hyperlink off this thread makes a sack of it for some reason but a quick Google of sixity rocket iii 2294 spark plug gets me there

Checked it and all sixity's other Rocket spark plug links too, none specify the plug code.
Plus they're all for 4 sparks plugs, the Rocket needs 6.
If these boys are up to speed enough to get the quantity right, and they don't mention the plug code, I wouldn't be trusting them.

Perhaps Triumph warned against them because they can't vouch for anyone's plugs except their own T1290180, which is NGK DPR7EA-9.

we sent qty 6; 2 per cylinder here is the sku:
2040406072; if you put this sku on the sixity site you'll see these plug which above stated are good for 2011-2014 rocket 3's i believe you older rocket uses the older NGK so you may be good to go there; but these new ones may not be good for the newer bikes. I do believe the dealership received this message from Triumph.

LoL the part they sell is a pack of 4; if you input qty 6 into the little box on the webpage i'll bet you'll get 24 spark plugs in the mail

Again if these dudes are selling 4 plugs for a bike that needs 6, they're either not tuned in to what the Rocket needs on a fundamental level (which means they can't be trusted in their indication of these plugs being good for Rockets), or they want you to buy 2 sets (8 plugs) in order for you to get your requisite 6 hence more $$ for them.

Either way i wouldn't be buying off them

DPR7EA9 were the factory plugs in my 2010 Roadster.

Same plugs in my 2005std

 

[Triple Trouble]

My 2005 came with DPR8 but were changed to DPR7 when the update kit was installed.

Iridium plugs have higher resistance and reduce the potential power of the spark. There is no benefit for the Rocket using Iridium. Stick with the normal NGK plugs.
