Spark Plug Change out ?

I have a 04 TB EXT 4x4 and want to change out the plugs with Bosch 4+ . I know the factory ones are "so called good for 100k " but I do alot of highway travel. I see that there is one bolt to undo which has two stages, now thats off I am a bit afraid of pulling to hard to get the cap off. Is there a trick to get them them off or do I just pull?

Why on earth would you pay that much money for spark plugs?

Highway driving is easy on plugs.

How many miles do you have on them?

They have 40k on them

They have 40k on them
Leave them in and drive on

Yea, I would agree with the other posters here. I bought my Bosch Platinum +4 plugs in July, installed them on my 02 TB with about 50k on it, and I wish I would have got the Denso Iridium plugs instead. My TB doesnt get any better mileage than before, and the Denso plugs have performed better in the I6 than the +4s have. Ohh, well, Im a little upset for paying $35 for the plugs. Next time at 100k it will be the Densos.

I'm getting ready to R&R the plugs on my '02 TB and have been considering Iridium Plugs as I don't plan on doing this again for another 4 years. What makes you believe that the Iridiums are going to give longer service? Will they improve gas mileage?, etc. I'm not as much worried about the cost as I am about the time. Thx

I have heard really good reviews about them, but that is what I would put in, not exactly what everyone else might. I understand your concern, as I am the same way. I just think the Bosch Plat. +4s are way overhyped for what they actually do.
