I need some new sparkplugs and iv heard good news about the ngk tr55 plugs for our engines but i was woundering what is the diff between the
v-power TR55
GP-Platinum TR55GP
X2 Platinum PZTR5A-15
IX Iridium TR55IX
I know the double platnium is the most expensive but is the best one?
any info would be great thanks!

i use tr55ix's now. the iridium plug is suppose to be the hardest tips. i have had great luck with them.

 

V-power: Standard copper core plug, except NGK cuts a snazzy little groove in the electrode

Iridium TR55IX: 02Denali is right they have the hardest tips & seem to misfire less from what I have read. Good plugs

As far as the platinum's go, I havent had much experience with the NGK platinums. If they have a "double platinum" plug, that usually means that one is 100% platinum, whereas the standard one may only be 75% platinum or just have the platinum disc on the electrode. Long story short: If you have the $$$ I would get the iridiums.

thanks a bunch 02denali and juggernaut for the help. i think im going to get the TR55IX

 

Denso Iridium is what i use, works pretty good for me
