I own a 98 caravan with about 91,000 miles. It needs a tune up and I have no clue how to get to the rear 3 plugs (born and raised around SB chevys) Do you need to take the top of the intake plenum off? Can I get them from underneath? Any help?</P>

I just replaced mine in my 98 grand caravan . You can reach around the plenum by the throttle body and get the back 1 and middle 1 with a wrachet and plug wrench. The front plug you have to remove the top alternator bracket bolts and swing it rearward. Then you can access it from the left side of the intake. Took me an hour to do all 6 plugs. [8D]

 

Very difficult. I think you can take the air plenum off - but remember where all those vacuum lines go and be careful they can be brittle. If you cant see to install a plug why take a chance? I took mine to the dealer. Took less than 1 hour. Best $90 I have spent.
