I followed the advise on my EGR valve cleaning and so far everything is great...just need to get a PCV valve and I will be good there.

I need to replace my plugs and I know the Rodeo's can be tempermentel

It a 99' V6 2wd.....w/ 166K.......I did a tune up @ 100K

I was told either
DENSO
or
Champion

There are more then one type for each...which have you all had the best results with???

I bought NGK, but it does not look like they will be going in..

Thanks

I have a 99 v6 auto 4x4 and I put in the NGK's. Not a problem at all. I think the NGK's are one of the few that work well for the 99. I'd use them.
