I have tried searching but have not found much. I just picked up some plugs, haven't installed them yet, but want to know if the BPR7ES is the proper plug for a IX with a few bolt ons. Also what gap would be best, stock?

 

I believe the BPR7ES' are for the Evo VIII. They will not fit a IX...

ninja edit

 

he's right, except for the evo XIII. they are for the evo VIII.

 

k, so do you know which plugs I should get for the IX? I am for some reason just having one hell of a time finding out what kind of plugs I can get besides OEM . I'm just looking to go one step colder. So hopefully someone can help me.

 

Copper or iridiums? These are iridium they will last longer than copper but is more expensive and is one step colder NGK LFR7AIX. Yes there for the IX

 

Thank you. So LFR7AIX is the plus to ask for at the store?
also what gap should I start with?

 

.26-.28

 

and you wont be able to find them at the store more then likely. Go to spark plugs . com and type in that model number... that is the cheapest place i have found them.

 

I use stock.....they work just fine, for now atleast.

 

the stockers hold up well for the ix

unlikely you need to change them with mild bolt ons

 

depends on how you use your car, if you track it, if you run leaded race fuel etc.... when i changed mine the first time, they were pretty nasty looking
