good price, seems good quality
t was a lot more reasonable than other opti sparks I found. The quality looks decent. I put it in and am running good. I hope it holds up. So far it is worth the price.

Nice build. Installed in my 1994 Buick Roadmaster wagon 5.7L lt1 v8. Engine is running smooth.

Broken when received!
COMPLETE CRAP! Item came with a broken spark plug port, making it useless. And because I didn't go to install it until after the 30 day period after purchase, I just got screwed. Spend a little more and go with a reputable product.
