Evo 9 Spark Plug List, Also how to read plugs.
ITS RECOMMEND FOR EVERY 100HP OVER STOCK, 1 STEP COLDER
Here is a list I compiled from a few post: NGK: LFR7AIX - Stock Heat Range ($8.00 each sparkplugs.com), For those with local advance autos ($12.99 each) ILFR7H - Factory Plug ($11.71 each sparkplugs.com), For those with local advance autos ($18.99 each) R7437-8 - 1 Step Colder Racing plug ($41.52 each sparkplugs.com) Denso: IKH22 - Stock Heat Range ($11.95 each sparkplugs.com) IKH24 - 1 Step Colder ($11.95 each sparkplugs.com) IKH27 - 2 Steps Colder Stock/Lightly modded cars I would use stock heat range. Full Bolt-on/Swaped Turbo cars I would recommend colder plugs.

Stock gap for IX plugs is 0.020 - 0.024. This is different from the VIIIs.. so us folks with IXs need to be aware of this when reading about what other people gap their plugs to. Below is from the IX service manual.. https://img523.imageshack.us/img523/3415/ixplugsjd9.jpg And how to read the plugs: http://www.ngksparkplugs.com/techinf...q/faqread2.asp MORE INFO

lol you must have got tired of people asking :)
I'm running the IKH24 and they work perfect. |
Dont forget Buschur sells NGK std. plugs for the IX, dunno what part # or where they got them because NGK doesnt even know about them.
But I talked to a guy who runs them and said the are NGK, they are non-iridium and they are the correct length. I think they are like $25.00 for a set or something like that? I asked for a part number but they wouldn't give it to me.....but I know of 2 people (myself included) who contacted NGK direct and they had no clue what I was talking about. So figure that one out? :beer: |
Just wanted to make finding the information alot easier. It took me 40 mins to dig through all the crap.
Im at the point of need plugs now. Stock Evo Plugs +18500 miles + GT30R = no power |
Don't forget these plugs. They are copper core. So you will have to change them more often. For the price I don't mind changing them with every oil change.
NGK BPR7ES - Stock heat range. $2.24 each Sparkplugs.com NGK BPR8ES - 1 step colder. $2.24 each Sparkplugs.com From what I have read people gap these plugs at .026 |

People are giving out wrong info then. Damn good thing I never bought them.

you can also use HKS S40IL (1 step colder than OEM).
they look the same as the Denso IKH24 - so I guess they are Denso plugs I also find a racing version of the IKH24 named IKH01-24 but I've never tested it. |
IKH27 is 2 steps colder if you want to add those to your list as well.
Thank you for compiling all the info... this may stop me from answering 2 or 3 PM's per week :) Are you sure about the stock gap ? i could have sworn it was .024 |
thanks, done
|
I have pretty much about every bolt on..! I use stock IX plugs.. would 1 step colder benefit me..??
Will these work on the EVO IX?? http://cgi.ebay.com/ebaymotors/4-DEN...ayphotohosting |

|
