i have the stock spark plugs and was wondering which ones would be better for n/a..i heard the ngk plugs were good but which ones? help ould be appreciated cause i have the money to but them today.

 

I have have the E3 plugs. Awsome. Have seen them on Horse Power TV on a dyno pull and they made more power over the normal plugs.

E3 plugs are in my truck and my pops truck. We both felt a differance in power.

Juse some more input on them. http://www.dslreports.com/forum/r205...00-Mile-Review

 

NGK TR55 for NA applications

NGK TR6 for FI applications

Both are available as a copper, platinum, or iridium spark plug....

 

how many miles are on your stock plugs? i vote to leave the stockers in there if it hasnt hit 100k yet or you dont plan to spray anytime soon. these trucks come with great plugs from the factory.

 

i got 45000 miles on the stockers i tried the e3 plugs it felt good at first but for some reason it felt like it lost some after a day or so...

 

and i do plan to spray as soon as i can get enough cash for the whole kit

 

Mine were replace recently to the NGK55's... and they're not that expensive.

 

were they worth it?

 

Yeah... I picked them up from the Zone. Readily available.

 

the zone didnt have any and oreillys said that they have them but they are the v power???
