Best Spark Plugs

I'm sure that you are going to get a lot of different suggestions when it comes to this, but I love my NGK's. I'm running UR5's gapped at .030. As for the E-3's, I don't know of anyone that is running them so I can't comment on them. Nice looking GN you have there. Cheers!!

I tried the E3s ($6.00 a piece) and got 24 MPG but the engine was hard to start

I switched to ACs and got 14 MPG and the engine ran better and performed better.

Both gaped at .28 inch

Check this out:

Don't know how factual video really is. Looks plausible.
If that's accurate I feel really bad for them having to work in those conditions.

With nothing else changed you seen a MPG difference that significant? That's mind blowing.

I had E3 plugs for a short while. Car idled a bit rough. Car was new to me & I figured it was the V-6 idle quality. Learned a bit more & replaced plugs. The driver side rear E3 was black & looked like it had never fired. Idle quality & overall performance was much improved with the new plugs!

How bout when you get to 25 to 30 lbs of boost , What then and what gap ?
Word is on the street that the Brisk plugs are the ones to run for all out applications that have sensitive computerized equipment requiring a resister non-projected tip plug.

And as far as gap, I would run .018"-.022" at that boost level regardless of how powerful you think your ignition is.

Turbobitt-Where can you buy them at and what's the cost?
