I only know of probably 3 people that have ran nitrous on the Fit. 2 of them dont post anymore and the last person is out of the US.

What shot are you planning to run? Im still wanting to run a 75shot.
I think Ill get a clutch first. The OEM will hold it, but Im almost at 22k on my car. Rather not chance it.

 

have a 50 shot... but havent tried it yet im at 27k and ive been babyin it till now. im gonna try and upgrade to some ngk iridiums but i just gotta cross reference the sizes.

 

805FitSport, who was an active member on here did a 100shot. Stock motor, trans, and clutch. Held it fine he said.
I dont know how many times he ran it though.

On a 75shot and some bolt ons he ran a 13.9@98-99mph on streets. Pretty damn quick for a Fit. Even if its fed.

 

First you don't cross reference SIZES. But anyway doesn't the USDM version come with Iridiums as standard equipment like the rest of the world????

You may want to check what you have before spending money on something you already have.

And with all the problems you are having hooking up your "Boxes" you might want to think about trying to install the 50 shot by yourself.

 

ooops my bad I meant to say cross reference the spark plugs but anyway I believe that the factory NGK are iridium platinum and are not a step colder like I want. I know Denso makes full Iridiums and ZEX makes there own spark plugs I just wanna make sure they fit... but before i do all that lol i wanna make sure my nitrous works and atleast sprays the 50 shot first

 

man 13.9 thas pretty quick on only a 75shot. Man wish i could work on my car in the dark!

 

There are no one step colder NGK Iridiums made yet. Standard center electrode ones are available.

 

spoon has racing plugs that are temp 8. they are repackaged denso ones though.

 

oo ok then guess il look into the denso's or the ZEX ones

 

What are you quoting me for? Like I said there are no NGK IRIDIUM colder ones available. Not that there aren't any colder ones. That's Not what he asked.

And 8's are TWO steps colder not one.

 

are those spoon plugs in a package you can get somewhere?

 

im not sure. i got mine from opak but id say just google "spoon racing plugs". its a good mod for those of us going the forced induction route.

 

When running any kind of FI/Nitrous just avoid platinum. They run hotter.
I say get the same cold range as the OEM plugs, just not platinum. Bring the gap down a bit.

Id also suggest not getting expensive plugs. With nitrous and how every many times you use it changing plugs is going to be often.

 

Just the TICKET $3.50 each, not platinum, one step colder, has the smaller gap. Use them for a month or two and throw them away and buy a new set for $14.00 ..... any questions.

 

set of 4 for $14.00 where?!?!

 

Any local parts jobbers, pep boys etc. I get mine at a local supplier for the dealerships in the area. They cost me $3.50 each X 4 do the math. While your there if you buy them in bulk like two boxes of 10 so you have 5 sets on hand you MAY even get them cheaper.
