i heard these are excellent for race applications,but has any body ran these on a stock n/a daily driver???

 

use the stock plugs. don't believe everything you read on the internet.

The advantage these have over stock plugs is that they're $3 a piece. This works in your favor when you accidentally flood the car and foul out plugs.

I know a local guy that runs them and he's seen tons of cars with them, mostly drag racing cars though. Not sure how they'd work in your application, you can try them and see. Do remember that you have to modify the rotor housings to fit them though or get a really thin walled 13/16ths socket to tighten them.
