Ohh okay then. That's prob why they run good and your not having problems. If they warranty them for 50k, then I guess that's almost 2 plug changes of reg plugs. if they go bad prior, then you could get them replaced.
How do they know if you put 50kmi on them? Did you have to give them your mileage or something? I would just get them warrantied for life if possible...lol

 

Pulstar has aweaome customer service when working with them in the past as well. The price from sparkplugs.com came to $127.97. I asked if they had any special promo code to save some money and kim told me they had a 10% off code, so that paid the shipping. As far as how u prove the warrenty, most of the time as long as they can look up and see your purchase from whenever they will send you what you need

 

dragon hemi must not do his own plugs, they sound good but be sure to keep us all informed on how they last or do in the hemi, ill be looking for new plugs in about 3k....

 

O yea, will do

 

about how many miles should you change your spark plugs?

 

30K by the book. 50K is probably sufficient.

 

i have like 90k on my truck and i dont think mine have been changed unless the dealer did it along time ago when the guy before me had it! i have a 06 mega it is soo slow off a stop think changing the plugs will help

 

It deff should if its been 90k, id check that air filter too

 

Agreed, but I still couldnt find them for no $8 a plug

 

Sparkplugs.com for the copper ones, when u search for your vehicle on there it says they dnt make one for the 05 hemi, but they do. The ones u need are EF-1s. If u dnt want to go thru them, pulstarplugs.com sell em for the 7.95 price too. Btw still working great
