Can someone confirm the ik22 spark plug p/n
Hi folks,
Finally hit 100k, doing the plugs among other things. I've decided to try the colder heat range plugs. Can someone confirm these will fit in my fit (pun intended).

On another note, some people have installed IK22-5310 on here and they work perfectly

What was the one's jackson racing used to recommend? That article has been long gone, I don't even think the make superchargers for the gd3 anymore.

They stopped making the supercharger kit for GD3, even if you do find them on sites. It's most likely hasn't been updated in a long time. In my opinion go with colder spark plugs if you want a better performance.
I'd recommend IK22

sorry to bring up an old thread. i am looking to change my sparkplugs and was wondering if there was any pros and cons of using ik22 spark plugs. i have a gd3 and the engine is completely stock. would i benefit from it, and would the ik22 do any harm to the stock engine? thanks

The only negative thing about running colder plugs is it seems to take an extra rotation or two to start the car when its really cold outside (below 10-15*F)
I think cold plugs matched with 91 octane fuel is quite the package performance deal. Car simply feels a bit more alive. Also gets better mileage. It would probably take driving ALL year to justify the plug expense versus added gasmileage, and that is if you drive everyday.
The biggest thing is you can expect a bit longer life out of the spark plugs. Where you should be changing them between 80 and 100k miles,l you might be able to squeeze an extra 10-20k miles out of them

Perfectly safe.
The GDs should actually respond slightly better, since they are lighter then the GE I drive.
Remember, the stock plugs are IK20s (denso) or NGK6 heat ranges. the IK22s are only ONE step colder. Ive pondered trying IK24s since I have no cats, a good intake setup, and run 91 or 93 octane fuel.
In the most basic terms, think of one step colder plugs as reducing potential detonation. The ecu is constantly monitoring with the knock sensor, and when it sees less activity, it pushes the ignition timing that lil extra bit further.

I plan on Honda doing this during my 1st oil change. As you see I drive 13'. What plug model plus 93 will let me see the power gains the GD's are seeing if even possible. My good friend who is a Honda tech thinks this set-up is ass backwards. He said go one step hotter w/ 93 octane would give me extra useable power.
What say you?
btw, i get cost with honda stuff so which s2k plugs? F20C or F22?

The plug gap on the IK22 is much smaller than stock and the plugs are shorter, which I assume changes their position in the chamber, I'm not sure how that helps or hurts the flame front.
Midrange has seemed to improve, I don't know how much of that is the new plugs and how much of that is the different plugs, but I'm sure not taking them out again and it runs well, so I'll leave it.

Since they are shorter, the chamber actually sees SLIGHTLY less compression, but the spark is more reliable and can last the entire burn.
I dropped nearly 0.15 seconds off my quartermile with just the sparkplug swap alone.
I think colder plugs are more towards spark reliability and detonation-resistance.
I am curious why he thinks a hotter plug would work. Some toyota camries and corollas of old ran a Denso IK16 factory, and a simple thing like denso IK20s improved engine response a LOT since the ecu was not seeing as much detonation events during its range of ignition advancement.

I'm sorry to resurrect this thread, but it feels more appropriate than reposting. I'm finding two part numbers for Denso IK22s - There's a Denso 5310 and a Denso 5358 which is what RockAuto has catalogued for the Fit. Will they both work? Is there a difference?
Should I have any concern my car will not start when it gets down to -10*F? This is not a common temperature here in Boston but it also does happen reliably every year once or twice in January.

@fujisawa the 5310 is the 22 heat range, which is a step colder than the 5358 which is heat range 20.
If you're looking for IK22, the 5310 is it.
The stock plugs are heat range 20 (in Denso terms), so those would be the 5358.
Both will fit. No pun intended.
I don't think that the spark plugs will be the issue in starting the car at -10F, lots of other factors come in to play in that weather. Brrr.

Thank you!!
Yes temp below around +20f starts to feel like not too much fun. Below zero is quite cold around here.
My Fit generally won't start below -10 anyway. Even with a new battery. Its undersized. I don't think Honda understands cold weather. But I have a full size jump starting battery in the basement now if that happens 😊
24 year old del sol starts just fine...
