I bought a set for my ej20 and haven't had a chance to try them yet. Just wondering if anyone else has tried them yet. They should work good for a boosted engine I would think.

Hmm, 109 views but no responses. Must not be anyone but me using them. I'll let you all know how they work.
I've only ever used the NGK LFR7AIX / 2309s, pretty much the recommended subaru EJ plug every where. However, none of the fitment guides say they'll fit but they certainly do...

The unique ground strap configuration on the E3 may provide longer life for a daily driver (more sharp edges to jump a spark) but that huge heat sink is not what most racers would select for a high performance engine, especially one using power adders. That's significant more mass to cool than the common "J" style ground strap which sheds heat quickly, especially the shorter "race" versions. A hot ground strap can cause pre-ignition. And I don't know how you would read that ground strap to determine if the advance is correct. On a common "J" style ground you can read the position of the color stripe to set your advance.
Use them and evaluate how they work. But unless you have a specific test methodology with measurable results all you're doing is going by perception which is unreliable at best.

This is why I started the thread. Useful information. Just looking at the E3 plugs, one thing that I thought is that they may not blow out like conventions plugs when improperly indexed, when used on forced induction motors.
