First off, I have a ralliart and gts sportback for utility purpose. Now I know this is cluRALLIART but my gts is so sad. I was thinking of E3 plugs or platinum plus fours. Also, can I use these in the ralliart?

I dunno if anyone but Mitsu makes an spark plug that works with the 4B11T. I sure haven't seen any for the EvoX or Ralliart.

HKS has their M-Series Super Fire Racing Spark Plug (M45XL) for the EVO X + RA. That's the only aftermarket one that I've seen.

I stand corrected. I wonder how much of a difference they would make over OEM.

Just use the Evo 10 OEM plugs in the Ralliart. They are 1 step colder and all you will ever need.

Forgive me, but what would that do as opposed to the OEM Ralliart plugs?

Should have a higher heat range if I'm not mistaken.

The Evo OEM plugs are 1 step colder and more detonation resistant because of it.

I thought evo x and ralliart has the same spark plug part number?

Nope.

Evo is ILKR8E6
RA is ILKR7E6

^Sweet. Thanks for the P/N, Bryan.
Maybe you can hook me up with the P/N look up.
I can post all the PN once & for all. :)

Those are NGK part numbers. I'd have to look up the Mitsu PN's.

Here are the links to them on sparkplugs.com
