couple of spark plug questions

[montess408]

i am looking for spark plugs for a 2003 impala with a 3400 in accel and i cant see any listing for them all i see is 96-01 are the all the same or ?
i called the local carquest and he wanted to sell me platnium plugs but arnt they bad for this motors ?
btw will the accel plugs listed for the 96-01 3400 work for my 3.1/3400 hybrid ?

The regular spark plug for 3100's (like my 94) will work just fine in the impala, but will wear faster. They now use an expensive dual tipped one that's iridium I think. It lasts longer. Gotta get dual though, not just single.

If you don't mind changing plugs occasionally, you can get the normal plugs for say a 94 3100 acdelco brand. I've always used them and they work great.

hey thanks for the fast reply

I'm getting ready to order some ac delco iridiums. They're about 6 bucks a piece. They have a single tip and carry a 100k mile warranty.

I pulled some plugs from a 2003 impala and it looked to me to be dual tip....

Our ignitions don't like single tip from what I remember.

No they are all single electrode single ground. I ran the Iridiums in my truck. But my ignition ate them up and you cannot re gap them properly so I went to standard plugs.

[IsaacHayes]

Right I didn't mean dual ground or whatever, just both the ground and tip are coated.

aah.
