I just got my runner back from the dealership and they said it was misfiring and recommended a valve job. I think it has to do with the spark plugs I put on though... anyone know which spark plugs are best for this motor, and what to gap them with? Also, is there a way to tell if a valve is bent? Thanks

 

every one here will say to go with oem or ngk v-power

 

I'm very happy with Nippondenso (Denso) plugs although NGK are also great. I change them every 30K miles. I don't have my manual at work so I can't tell you the gap but I THINK it's .042 Don't quote me on that though.

 

avoid bosch...i run ngk iridium and are happy with em...are you wondering if the valve stem is bent? not much of a way to tell without the valve out i dont think

 

You could run a compression check...

 

Nippon denso platinums iirc
Or NGK platinums.


If you even think about bosche I will track you down and beat the snot out of you with a foam noodle!! LOL Point being anything but bosche...lol

 

ngk or denso regular type OEM are best

.031 gap

 

Curious as to why there is a strong opinion against Bosch plugs.

 

Thats all I run on all of my Toyota's as well. I tend to lean more towards ND since they seem like a better constucted plug than NGK. Autozone sells the ND's.

Ngk's here.Good plug.

 

because they suck. Suck from a performance and longevity stand point and that they unneccisarily suck money from your wallet. Kinda like how our TV sucks.....

 

I use the NGK G-Power BKR5EGP. Very tough plug.
