Looking to replace stock spark plugs with aftermarket plugs...
#4
Denso does not list a Fit app: (Find My Part: DENSO Iridium)
Not sure these plugs would add anything to a Fit anyway.
#6
I'm running pulstar plugs on my gd just out of curiosity and I don't seem to notice any power gain unless I dyno it then I would know if I gain power or not but then again not worth the dyno. MPG wise I don't keep track also I'm running the Blitz TC so I'm probably losing a bit on MPG. but I definitly feel the response on the TC woot! woot!

I would stick to the plug recommended in the manual, ive seen many cars suffer problems and even obd codes getting thrown, when using a different plug than is listed in the manual. the engineers design the coils around the spark plug they are going to use in production.... i know the commercials and adds look cool, with plugs that have 6 electrodes everywhere, and promises of 'super spark' super ignition' but there really is no power to be made, no mpg's to be found.
its a lot of advertising

i think the spark plug adds are funny. super spark or even extreme spark makes more hp is the biggest crock of crap. with the spark plug you either have spark or you dont. you cant have more spark unless you make a bigger gap and more spark does nothing. its like using 1 match to light a cup of gasoline or using 13 matches to light the same cup of gas. the gas will burn no matter how many matches you use.

NGK's only plug for Fit: http://www.ngksparkplugs.com/apps/ca...uv/results.asp
Denso does not list a Fit app: (Find My Part: DENSO Iridium)

Because my car has over 75000 miles on the odometer and there is now a KraftWerks supercharger kit sitting in the engine bay. I wanted plugs 1 step colder than stock.

I'll ask a Honda parts man I use in Seattle, but I am pretty sure the OEM plugs are Denso Iridiums and you will not find a better plug. Denso has kept a step ahead of NGK with smaller electrodes and less juice required to fire, but they are more expensive.

IX Plugs
This is the plug I am running
Iridium IX BKR7EIX-11
These are 1 step colder than stock.
They were recomended by a friend in the Know....catch my drift?
No problems and the car runs good.
About 10000 miles on then so far.
Hope this helps Gary

Your friend gave good advice on going to a colder heat range plug. I am not sure if that would be the way to go for someone living in the Minnesota area, with the sub zero weather they are having right now.

You guys have all the info you need, and thanks for the link, polaski, it's really helpful. I got this response from a Seattle parts man I use and it kind of baffles me - he did reiterate that Honda used both NGK and Denso plugs in 08 Fits, but at first he said they were platinum plugs, and when I asked for clarification, he said:
Iridium is a component of Platinum, So yes the Platinum plugs have Iridium in them.
The 2008 Fit came from the factory with both Nippondenso and NGK plugs.
You will have to pull one of your sparkplugs to see if it’s an N/D or a NGK.
Platinum plugs have a life of 60,000 miles. So you’re not going to have to change them like non platinum at 30,000 miles (Not sure how many miles you have on you Fit)
I just have trepidation about platinum plugs after having really bad experiences with Bosch Platinum plugs in the past. I have had great experience with Iridiums, even in my snowmachine. Anyone know what he's talking about?

Using a larger gap on my Neon didn't increased power but increased milleage somewhat (something like 10 kilometers more on one tank!) as well as better responsiveness... I guess it would do fair in the Fit but i'm too lazy to check out in those -30 something... (-41°c at Valcartier to be Exact! :P)
