what are the best type of spark plugs to run in the L's?

 

new ones, replace those suckers as often as you can

 

Plug selection will depend on your engine mods.
Post your mods and you will recieve sound advice.

 

I have full bassani exhaust,80mm Maf,diablo chip,so what plugs are needed for this thank you

 

I am fixing to change from a 80mm to 90 idf that makes a difference!

 

What do you think about NGK TR5's boys?

 

Running the denso It22's in mine and luv them

 

You only need the denso IT 20's with that setup.

There well worth the money for the plugs. I'm upgrading to the IT24's in a couple days and getting rid of the NGK br7's. Iridium is the way to go if you don't drag race the hell out of your truck.

 

DENSO'S ..........something along the lines of pay me now or pay me later
