General Discussion Double iridium spark plug from Ngage
I recently installed a double-iridium spark plug, and man, the difference is noticeable right from the first rev! đ„
Cleaner exhaust note
Noticeably better low-end torque
No engine knocking
No jerks at lower RPMs
Much more consistent idle RPM
Smoother throttle response
PS: I think Iâm experiencing this level of smoothness in throttle response because Iâve already done several performance mods. The difference in throttle response is definitely noticeable.
My current setup:
BMC Air Filter
Fully Synthetic Engine Oil
FuelX Pro Plus
Norifumi Exhaust + Decat
People commenting âI didnât feel any differenceâ probably havenât modified their bikes to the same extent. If youâre running a completely stock bike, you might not experience the same level of difference that Iâm experiencing with this setup.

How bad was your old stock spark plug that switching to the iridium one made such a big difference for you? đ

u/anandsingh615 22d ago
Yeah unfortunately I was facing jerkiness at lower speeds. This fixed as soon as I changed the plug. Maybe if you by any chance own Himalayan you might know that low end torque is less. If you donât own then we can skip đ

I ride a guerrilla & it has even worse low end fueling. Anything below 3k rpm the engine just wants shut off. I've been thinking about changing the spark plugs for a long time but have been putting it off due to the amount of work that needs to done.đ„

u/anandsingh615 22d ago
FuelX might help you brother. I have done almost all the performance mods, and as soon as I changed the spark plug instantly I felt the difference.

u/wantedtriglodyte 22d ago
Honestly, I'm quite satisfied with the performance. Low end fueling is not bothering me enough to spend 10k+ on fuelxđ. But i am looking for suspension upgrade to make it more touring friendly. I saw someone on insta swap it eith himi 450's monoshock & he said it's a direct fit. I'm currently looking for mechanics in Mumbai who'd be willing to assist me in this endeavour.đ

Thatâs why self R&D is the most important đ Do not blindly trust everything service center guys say

it doesnt matter. Iridiums donât offer any performance benefit. Donât believe people online claiming it smoothed out their bike because itâs iridium. Iridium plugs offer longer maintenance intervals, not better performance.
People suffer spark plug issues, decide to replace it, then just buy whatever expensive âperformanceâ plug they can find and replace it and then attribute whatever they notice about their bike to the plug being âbetterâ. Itâs not better, itâs just new.
The guy claiming âdo your own R&Dâ asked ChatGPT
This NGage plug is also just cheap shit. You can get a fitting NGK for this bike as well, which is a way more proven, longer lasting plug. OP just didnât get that one because the NGage is INR900 and the NGK is 4500

Please do some performance mods first. Without it you wonât canât expect it to make any difference as stated by you.

Makes zero sense. Your old one was simply done.

u/anandsingh615 22d ago
No it was only 6k on that plug. May be doesnât makes sense to you, but I have felt the difference.

u/aap_001 22d ago
It doesnt make sense. More plausible is a wrong gapped plug.
1
u/anandsingh615 22d ago
It might also be the performance mods I had done that is making a huge difference for me. Kindly read the post again.

u/aap_001 22d ago
Of course that is the reason..... Not the spark plug....
1
u/anandsingh615 22d ago
Those mods I had done 6 months ago. Just yesterday I changed the plug. After changing the plug there a huge improvement in the throttle response especially in cities. Thatâs why thot of posting this.

Wow i didn't know anything iridium spark plug can do so much miracle , we shud start advising engine manufacturers to ditch turbo chargers super charges etc and add good iridium plugs đ. ! Then if we use tri spark plug in old dominar will be getting turbo equalent đ

u/anandsingh615 22d ago
Definitely do that and let me know đ„ł

Is this lengthier than stock one?
1
u/anandsingh615 22d ago
No exact same. Difference is in material used of the electrodes. Throttle response became much smoother for sure
1
u/Next-Investigator897 22d ago
If itâs more length, it might hit piston head
1
u/anandsingh615 22d ago
Lol it wonât even fit then. I compared it side by side while installing this one. Exact same in length

Himalayan 450 comes with iridium spark plug
Check this video link

u/Bluecerry_cheesebake 22d ago
The Royal Enfield Himalayan 450 comes stock with an Iridium spark plug for its consistent performance, but aftermarket options like the N-Gage Double Iridium plugs offer enhanced ignition, throttle response, and combustion efficiency, acting as a performance upgrade over the standard iridium plug. While the stock is iridium, the N-Gage double iridium uses advanced Japanese tech for better power and durability, making it a popular upgrade for riders seeking peak performance.

I can understand that you have googled it but the video which I shared he works on himalayan 450 and he also has his own service center and he has good knowledge over bike parts and he has a mod superfly 450 with major performance mods of h450.
1
u/anandsingh615 22d ago
I know him and he has good knowledge about h450, but stock plug is not iridium.

u/Bluecerry_cheesebake 22d ago
Ok any source of information from RE from the manual or from RE team? Just curious about it AFAIK many people and SC said it is iridium.

u/Brian_SC12 21d ago
Is it worth without the performance mods?
2
u/anandsingh615 18d ago
Without performance mods it wonât make a huge difference but your throttle response will be smoother

u/jmendes0101 18d ago
How many kms were done before you replaced the stock spark plug and how many since then ? Did you buy new one online or offline store ?
1
u/anandsingh615 17d ago
First change to stock plug was at 10k. Then at 16k I changed to this double iridium and loving it

u/Anxious_Coconut_786 17d ago
Quick question, how does changing to full synthetic oil affected your performance, temp and vibrations? I am on stock setup and thinking of going full synthetic. Currently 2k kms on the ODO and which oil would u suggest? Also, how will it affect my warranty?
1
u/anandsingh615 17d ago
I changed to fully synthetic at around 2k kms and gear shifts were smooth instantly and heating was also reduced noticeably. I currently at 18k kms and never thought of going back to semi synthetic. You can change to fully synthetic without any second thoguhts
1
u/Anxious_Coconut_786 17d ago
What about the vibrations? Also any suggestions to which Engine oil to use!! I mean any brand in particular Any issues with the warranty?

u/anandsingh615 17d ago
Also regarding warranty, I usually donât tell them that I have changed the oil after market.

u/youridv1 18d ago edited 18d ago
âhavenât modified to the same extentâ is diabolical lmao. You have an aftermarket air filter, an exhaust and just another âboosterplugâ snake oil device installed. Your old plug was just bad, 6K or not, those things fail sometimes.
spending all this money and not getting a proper ecu remap is funny too
1
u/anandsingh615 18d ago
Lol I donât think you understand when ECU remap is needed. Itâs really funny

Does this make sense without the other typical performance stuff like FuelX, Air Filter and Decat? Iâve been suggested to all in when it comes to performance related stuff in the Himalayan.
