I've decided I want to do a little tune up on my 04 GT. I was looking on American Muscle at the spark plugs they have... There are 2 types that would work in my car:
$60 Zex Power Tune Spark Plugs
$20 NGK V-Power Performance Spark Plugs

Both of them have pretty good reviews, except for the Zex has one bad 1 star review. I was just wondering if there was a big difference between the two and if it was worth it to go ahead and get the Zex plugs. Thanks

Yes there is a big difference $40.00 get the NGK's and a tank of gas.

if you dont have any power adders go to your local parts store and get 8 autolight AP104 plugs and gap them at .054 and call it a day.

Thanks for the replies. Right now, it is just stock but I am ordering a k&n cold air intake as well as a plenum, throttlebody, and spacer in a couple of weeks. If I'm trying to get the best for my car and I plan on doings some mods soon, is it "get what you pay for" here or do both of these plugs work about the same?

They're both basically the same. Don't kid yourself.

This is the best advice anybody can give you. Chances are if you go with an FI setup or nitrous down the road you might be getting a set of plugs that are a colder plug at that point anyway. Don't waste your money, the stock plugs are going to do you just fine right now, just like a stock set of coils will.

Just get the Autolite plugs as mentioned above, and skip the tb spacer.

Skip the spacer, and most people will tell you to skip the intake and just get a K&N drop-in filter and remove the silencer. Your money is best spent elsewhere; trust me, there's a few mods I have that I wish I wouldn't have done and spent my money on something more useful.

Even better, go get 8 Autolite 103 plugs which is identical to the TR6 and cost about $1.29 each. I even run them in my pops Town Car. They are one step colder than stock, no Platinum crap, and will go 20K miles without missing a beat. They are the perfect plug for anybody but a taxi cab driver.

Awesome, thanks for the advice everyone.
