I have the +2's in mine. Seem fine and less money than the +4's.

Many people will warn against the bosch's but since you did ok with them, then maybe youre ok...personally, im running motorcraft double platinums, and i have the jba powercables-great combination now that its all in right lol



Good luck

I (hopefully) am going to be installing the OEM plugs w/ Taylor-Vortec wires this weekend. I have heard that Denso Iridium plugs also work well.

Through the wheel wells. Easier if the tires are off. So block the Trac up very safely...

I recomend nothing but the OE plugs. I have fixed a few situations where Bosh plugs made the vehicle run worse then bad plugs do.

Well, he says he did 70 kilometres on them. I don't think that's so good! About 44 miles.



Curious as to why folks change plugs so much - is it just a need to do something?

grump, I think at least part of the reason depends on how long you're going to keep the vehicle. The first scheduled tune-up in our trac is @ 100k miles, and if you aren't planning on keeping your trac beyond that, that's fine. However, if you're keeping it, 50-60k miles is a bit more realistic, if for no other reason, to prevent galling. Even if you don't swap the plugs backing them off and adding a bit of anti-seize would be a good idea. The plugs aren't going to be happy to come out if you wait the full 100k and despite pulling the wheel on the passenger side, one or two of the plugs is still fairly difficult to break loose.
