My 2000 SWB 3.3 is at 155K miles. I changed the plugs at 75K. Did the front and took the rears to Pepboys. I was planning to change them at 175K miles, but this weekend while changing the oil, I decided to check the condition of one of the front plugs. The wire was stuck, the boot came off, the plug gap was pretty wide and some burning on the base and around, so overall not good. These are the OEM Champion Double Platinum. My smog test is in a month or two.

I have decided to change the plugs myself. I have searched this up and down. I know 2001 and up is much easier. On my 2000, I am planning to take the wiper cowl and the alternator bracket off. I believe I took the bracket off once without even messing with the belt. But even then, do I have enough room?
I have long thin arm (6' tall, 150 lbs!). Can I just reach back there without taking the plenum off? What if I take the front motor mount off and tilt the engine as some manuals suggest?

The reason I ask is, if it involves taking the plenum off, then I might just pay the $150 to pepboys. I don't like the bellow approach, mostly because I am sure I won't get the #1 out anyway.

The van is running fine. Starts are not as easy as they used to be, more noticeable since I put the new battery in. Still starts fine and has the same gas mileage (16 in town and 21-22 hwy). I know these plugs last a long time, but bear in mind that the last 50K miles is almost exclusively in stop and go traffic with the wife hauling the kids around town. I think that takes a toll on everything. The spark plug base looked coked and worse than the tip itself.

This weekend I have to do the pan drop and ATF change, the fluid has turned brown just after 25K miles. Then my other car is due for brake fluid flush. I have sourced the plugs at a good price, will see if my lower back cooperates.
