Oscar Jackson Sr. on Spark Plugs
Update: I have drove my car for over 60 miles now with the new IK20s and I love them. I think positioning the spark plugs so that they are in line with the intake manifold probably helped too. I think Doc wrote something on this so I started to research it and it seems to help to have the spark plugs lined up but I think it just helps to burn more efficiently.
All I have to say is that the Fit runs real nice with that setup.

Here is more on the indexing of spark plugs. I dont know if it really works I just did it to see if it did.
I do know that that IK20s helped smooth the engine out compared to what it was.
I did read up that the iridium's are supposed to come gaped so I probably got the wrong IK20 from advance auto for another car. I did gap them and was careful to not chip the tip.

I'll wait til highboost comes out. Seems like you guys are pulling a Gran Turismo with this kit lol by the time it comes out I should be able to afford it + the plugs + gauges/pod + injector upgrade + Spoon catback + T1R test pipe + T1R header. Christ I need to put away more money per month. I plan to do all this by the end of the year. I <3 you Kraftwerks lol
I checked out the link on indexing and found it to be a good read.... If my math is correct, there is a possible power gain at the drive wheels of 4 H.P. give or take for unknown variables and a fuel mileage improvement as well.... In the article the guy just cleaned and squared the edges of his spark plugs and didn't even install new ones.. That is something that I have done a lot of in the days of points and capacitor ignitions, especially on British cars and bikes with Lucas electrics, air cooled VWs and 2 strokes... I fouled some IK20s and guess that I need to see if they will clean up enough to try to do this trick with.

well I was planning on instaling them when I did my oil but they sent me the wrong ones.. I got ik24 plugs when i ordered ik22. Called and lefted a message with oscar jr. hopfully ill get them next week.
DOHCtor, I have heard of indexing spark plugs so as not to disrupt the flow inside the combustion chamber, not sure if it's the flow of fuel or combustion flow inside, but was told that in can affect how a car runs. I just don't know on how this "indexing" method is done. Care to share on how this is done? Thanks!!!

Marko!!
i notice when i installed these plugs.....at some point it isn't as smooth as OEM plugs....but at some point it feels faster......did i do something wrong or are they just like that ?
thanks
thanks
Did you use anti-seize on the threads?
So my car started doing the same old song and dance. While I idle at lights the car will some times sputter and stall out. I pulled the plugs out and this is what they looked like.

Is this sign of running rich or lean? I had the IK22's for only a month and maybe 2,000 miles, what the hell is going on with my car.

Actually, they did test it on an N/A Fit in front of serveral Fit owners at the Fit Meet they hosted. The stock plug baseline at 99WHP, and after the spark plug swap, it went up to 102WHP. Basically this is a relative cheap upgrade that will give you the same results as putting on an intake or exhaust.
My car sometimes (quite randomly) will dip down to 500 rpm or so when I come to a stop and idle, then go back up to 650-750... I can't get this to happen consistently and it's a little disconcerting to hear the engine sputter all of a sudden after I get to a stop. Is this what you guys are mentioning?
