I am thinking of changing the plugs in my truck, the reason being is I have bosch plugs in there now and have heard bad things about them. Anyway I was searching for NGK Plugs and have found them at my local auto parts store I just dont know which ones you guys are reffering to when you say ngk TR55 they have a couple that say that. (1) & (2) & (3) say TR55

1.NGK 3951
V-Power Plug; TR55; @ Gap .060 @
1 Year Replacement Warranty $1.68 each

2. NGK 3403
G-Power Platinum Plug; TR55GP; @ Gap .060 @
3 Month Limited Warranty $2.99 each

3. NGK 7164
Iridium IX Plug; TR55IX; @ Gap Preset @
3 Month Limited Warranty $6.96 each


4. NGK 7862
OE Style Laser Platinum; PZTR5A-15; @ Gap .060 @
3 Month Limited Warranty $9.99 each



WHich one of these do you guys recommend?

Does anyone know why the cheapest one listed (1) offers a one year warranty and the other three only offer 3 months?

Is there any advantage to using the # (3)iridium or (4)oem style laser platinum plugs?

I hear the iridium plugs are awesome but dont last as long as the OEM plugs. I have read the stock OEM plugs are just as good as the NGK's.
