My '04 Pac has 105k on it and is due for spark plugs. Anyone have detailed instructions on replacing the front plugs? Looks like the intake needs to be removed first? Thanks!!

 

The plastic intake manifold is removed in order to gain access to the front bank of plugs.
It sounds like a more difficult job than it is, just a lot of 'stuff' to disassemble. Took about an hour - paraphrasing the service manual:
Disconnect throttle and cruise control cables, remove mounting bracket, disconnect electrical sensors (I think that there were 3 or 4 involved, remove Air filter and Air filter housing, remove bolts securing dipstick tube, oil fill pipe, front support bracket. Remove bolts securing intake manifold and lift it off of the silicone gasket and slide it a bit, back toward the firewall keeping the EGR tube connected. Now you have a clear shot at the plugs.
Just keep track of all of the things you disconnected/removed so you can put it all back togther.

 

Thanks for taking the time to respond. Looks pretty straightforward. What is the recommended plug for replacement? Should I stick with the OE plug? Thanks.

 

yes stick with the oem plugs

 

Absolutely stay with the OE plugs. Don't fall for the 'snake oil'.
