i am just wondering if anyone has tried them yet? just wanting to see if they are worth it. 25$ per plug, wow.

 

coppers are the best, buck eightyseven.

 

i see that everyone here says the coppers are the best. but i was just wondering if anybody had tried them. if i could get 5 more hp or2 more mpg i would give them a try.

my truck has 52k on it now and i havent changed the plugs yet. so i really couldnt get a good test on the pulstar, to see if they actually help.

 

throw them on anyways. might as well give it a shot. i can't see them doing that much though...well, $200 bucks worth anyways.

 

He drivinga 5.9 gas engine, they respond well to platinum plugs, unlike the HEMI. But copper are much cheaper and work just fine in the 360 also

 

i dont see how they could be much better than the platinums or iridium or plat+4. You can only improve the spark so much before you get to a point where your just over killing and wasting your time.

 

so you are saying that the platinum plugs are good for my 5.9? i put the +4's in my 5.4 ford and liked them alot. i would probably go with them if they are o.k.

 

yup

 

Plats work just fine in the 5.9

 

thank you, thank you. you guys just saved me some $.
