The plug you are looking for is BR7EF....those will be easy to find. .030 is good gap

That's not the same plug as he's asking for, but I would recommend it over what he's asking for. His part is the "TR7" projected plug BP7EFS, plug number 3626 and the BR7EF is 3346

Default 98 LS1 TT kit plug type

hope this does not change anything. but i am only running around 8 to 10psi though the motor. close to all the other kits you can get that are not custom made. So you all say NGK 3346s or 1094s and what would the good be for running a 1049 colder plug?


thanks again for helping me

Colder plug is usually better for more boost or crappy gas (less prone to pre-ignition).

8-9 psi, you can easily (safely) run the 4177's TR6 projected tip and they'll be less prone to fouling on you.
