colder plugs for h22

[92accordexpower]

So i searched, and found a bunch of threads about plugs for the f22, but nothing for the h22.

i want a 2-step colderplug for my h22 to run a 75 shot. the plug listed for an oem @ advance auto parts for the h22 is a zfr6f11. i can't find any listing for a zfr8, only a 7.

so what's the best plug to run on an h22 for 2 steps colder? and what would be a good plug gap.

Try going to the Zex website they have colder plugs

yea but everyone i talk to says not to use the zex plugs, instead just use normal NGK coppers. not to mention the zex plugs are $25 a set

use these there are 7 and 8's there about the same price through depending where you get them.

they will fit the H series with the .44 gap and etc...

PFR7G-11S
or these
IFR8H-11

these will work fine with n2o but these will not add performance but will allow you to make more power keep that in mind alright buddy

Do not run a .44 gap when running nitrous. You don't want to use a standard NGK plug because of the long exposed electrode such as this:


You want something more like this of the NGK racing plugs:


I run 9's on my setup with about a .35-.37 gap, I use this plug "R5671A-9"

different members have different opinions i use these since they are idrium and double platinum there not the ones you listed in the first pic. these plugs cost 17 bucks a piece these will work fine with n2o i used them no issues or anything... so its like 60 bucks a set...

BustedLX is right, do NOT use a plug with a lot of exposed electrode. It will heat up too much when using nitrous, and essentially act as a glow plug, causing detonation.
