Spark Plugs?

Its time to do a tune up on her and i was wondering whats the best plug to run. I was wondering what you all were running? :rock:

I like the Nip made plugs of NGK. I have the TR55 in my Z71

well.. I run bosch +4s no complaints.. 30k on them now still runs like new.

i've been wanting to try those, i usually go with the denso or ngk's.

the denso have been in my truck for two years now, look very clean and no probs,

I put the bousch platniums in when I swapped motors. When I did my head swap saturday they looked brand new. As far as performance I wouldn't know if they were any better than the next plug!

I normally run the TR55 but put one set of Autolite 305 in and they did good as well.

when i do mine...ill stick with the proven NGK's tr-55's or tr6's. i heard my buddy say the platinums messed his car up on the dyno last weekend, with a high end miss.

i run the tr55's as well and i like them. never pulled them to check but they have around 15K on them so far. i did put a set of bosche plus 4's in my uncles dodge and i think it made a rougher idle. only experience i have with those tho.

I'm running the NGK TR6 plugs. I changed to these when I was running the ProCharger and they do fine.

I put bosch platinum +4's in a 2002 prism and a 2000 cavalier. Both cars idled smoother and picked up +2mpg!
