Spark plugs and wires
 

I was wondering what are some good spark plugs and wires to upgrade to. I have a 1997 with the 3.4L V6. Let me know which ones you all have used. Thanks, Shane.

Does anyone know about the spark plug brands Denso and Bosch? Which one is better or is the price difference worth it?

Denso is a stock Japanese company that supplies parts to Mazda, Toyota, and Nissan, maybe more but thats what I know of.

Bosch is a general replacement company that has parts for everything.

In performance they are pretty much the same from what I've seen. If you want performance plugs and wires look for NGKs. I found some on the NGK site a while back but I don't know what if any gains you will get. Plugs and wires don't really do that much until you have a heavily modded engine but they could help a little. If you get some post a pic and any difference you notice. Happy modding!

From another marque's forum I hang out on, NGK's and the associated "blue" wires" are pretty much the plug/wire combo of choice.

If you have some extenuating circumstances, such as an offset spark plug in a hemispherical head with domed pistons, or you are routinely just a fraction of a second behind the guy taking first place in a competition, then it would be worth shelling out the big bucks for a set of Nology Hotwires. Now, I know there are a lot of naysayers out there about Hotwires, but in the two cases described above they worked for me.

Normal use, just go with NGK's and the blues.
