2000 Pontiac Bonneville Question: Replace Spark Plugs
There is still room back there but as you have noted, not as much as in 94. When the manufactures moved to 100,000 mile spark plug replacement intervals they began to worry less about access to the plugs. If you have a "shock tower brace" it may help to remove that. You can still replace the plugs from the top side. It is just a bit more work than before. I would also recommend replacing the spark plug wires at this time. After 100k miles you may find the wires very hard to remove from the plugs without damaging them. - Russ
