Yep Their expensive

I used a set when i took my tbird from omaha to NY, made it 1000 miles and it died to bearing failure due to gas in the oil from a scored cylinder from a wrist pin.

I'm using them

Installed them along with a Screamin' Demon coil pack and wires this spring. I'm running them gapped at .055 and no problems what so ever with 15lbs of boost. Great plugs, IMHO.

Don't recommend that heat range at 15psi+ boost but whatever I guess.
