I'm tellin' you man, for S/C cars, try the NGK BR7EF's.

 

yea, i just took a look at them... whats the difference between them and the TR6's? are they a cooler plug or anything or have a better spark?

 

Take my word for it Bro...I wouldn't steer you wrong. Try them, you won't be disappointed

 

hmmm.... im gonna have to give them a try then next time i change out my plugs... new plugs are goin in when it gets above 40 degree's outside... hahaha. what sucks is im alittle above 3k miles on the blower so i have to change my oil soon and its freezing cold right now, the mustang is white from snow.... hahaha. im running TR6's in my nitrous car too, do you think that plug will handle the juice... its a 125 shot on a 5.7 hemi.....

 

Not sure about the Mopar motors. But, I just couldn't believe the difference those plugs made over the TR6's. The car felt SO different. It was one of the best changes I did on the Mrs Stang

 

Could the same thing be said about going from stock plugs with 47k miles on them to the NGK TR55's?

Could any possible difference be noticed ?

 

hmmm... ur making me really excited about the difference now in switchin the plugs.... haha. did u notice any gas mileage difference? my gas mileage is like 12 city and 23 highway and i hope i can up it to like around 24-25 highway.... that wouldnt be so bad then...or atleast alittle better city... i gas up all the time recently... it seems like i get worse mileage in the cold but im not sure if its true or not.
btw, did u ever run the Mrs stang at the track?

 

u will notice a difference because ur suppose to change them every 30k and your probably losing some gas mileage and responsiveness and smoothness from having higher mileage plugs in there.
