Wondering what I should run on a IX with full tbe, fuel pump, flash, mbc set at 21psi.

 

stick with the stock ones

 

Until you've done a full set of bolt-ons, and are dying to turn up the boost and perhaps alter your fuel mix ---- stockers are fine. When the inevitable finally occurs, you'll probably want to run a step colder plug. Lancershop will sell you colder iridium NGK's for $144 a set, or Nolimit will sell you colder iridium Denso's for less than half of that. NGK versus Denso? Ask for Chris at nolimit.

 

can i switch to copper?

 

no

 

+1

 

+2 stick with the stock ones

 

Stock ones are just fine.

I ordered 2 step colder NGK's and I am gonna tune them in Thursday.

 

there aren't any for the IX, but even if there were, why would you want to? You'd be removing a $60 set of plugs that work great and last 60k miles while inserting an $8 set of plugs that isn't needed and only lasts 5k miles. I'm curious as to why you'd want to remove perfectly good parts to replace them with lesser parts.

 

stock IX plugs last 60k miles?

 

Iridium plugs can last 60k miles, and the stock plugs are Iridium.

 

denso ikh24 are 2 step colder for the ix's optionsauto sells them for like 45 plus shipping for all

 

2 steps colder? That sucks for most IXs, which would want 1 step colder at most.

 

I was thinking the same thing

 

explain why?

I run 11 steps colder in my GTI, for more boost on pump. So how is 2 bad
