No, I'm pretty sure they don't. I installed the same plugs without any washers just fine and I don't see any washers in the Haynes manual.

Edit: have fun with the back ones, I sure did.

A quick look at the Rock Auto listings looks like the 3400 uses tapered plugs. I don't remember offhand since it's been a while since I changed mine.

It's not too bad if you move the coil packs out of the way and have skinny hands.

Good advice, but it's a lot of fun if you don't move the coil packs.

Reminds me of my dad taking his Fiero to a Pontiac dealer that would only change the plugs on the front. He didn't know this till he took it somewhere else and they showed him.
