What spark plugs do you recommend for a 1999 4Runner 3.4L V6?

Can you tell me the brand and model?

Thanks.

Just get the dealer-supplied plugs. I think they are NGK's if I am not mistaken. They are around $2.00/plug, but in the bay area they are probably $3.00/plug

There have been a lot of posts on this topic. The conclusion is always stick with NGK or Denso. Definately stay away from Bosch.

NGK-R thats what i have in my truck.. the V-Power ones.... In my Toyota FSM, it says to use dealer NGK or Denso plugs.....

Denso. Bought mine from www.toyotapartsales.com. Significantly cheaper than my local dealer(s), and slightly cheaper than another online Toyota dealer. While I was at it, I bought a few oil filters, an air filter, an ignition cable set and a fuel filter.

BTW, though replacing the spark plugs is not a difficult job, it does take some time, especially the passenger side plugs.
