Why you bring plugs to dyno sessions
Customer recently came for a dyno tune. Luckily Proven Power had some 4644 plugs instock. To show customer difference I did a back to back within five minutes with NO changes to the tune. 100,000+ mile bone stock LS with individual throttle bodies

Copper plugs are cheap. Change them every oil change.

ZFR5F-11 I use those N/A
and
ZFR6F-11 I use these for boosted (8.5psi)
As a tuner do you prefer base sparkplugs or something along the lines of the NGK plugs posted above?

my lag is your courtesy head start
ATTENTION.... installing a head gasket, head studs or pistons and rods in your otherwise STOCK engine dose not make it a "built" engine! stop listing you cars for sale saying they are built when its not!!

since we are on the discussion of spark plugs.... just curious.....
I used to run the R5671a-8 plugs in my Car....
and have recnetly switched to the R5672a-8
same identical NGK plug EXCEPT the plug i am now running doesnt hhave any of the tip projected..... and the ones i used to run have the projected tip.
My car made mid 500s on race gas and mid 400s on pump gas.....
What is the pros / cons to running a projected tip vs. non projected tip... which is better.. ???
