spark plug and wires

those are fine. most will say go with toyota wires and ngk copper plugs though ive found

the plain old copper ones are better....

Is it just me, or do those look like 3SGTE wires? And the 91/92 5SFE wires are round, and the 93+ are square.

You can find these cheaper at SparkPlugs.com. I just bought the exact same wires w/ the exact same plugs from them.

really??

i was gona go turbo later, so i was thinkin bigger might be better.

stock are 5mm right?

You can find the OEM Toyota units from partznet for about that same price.

Copper plugs on a 5s are a waste in my opinion. You'll have to change them more often with no appreciable gain. A good brand of platimnum plugs and be done with it.

Just realized you're in Houston. Get your parts at Champion toyota (formerly Jay Marks) for the MR2 discount. Plus Jeff is a great guy.

They're still working. I don't know that I'd say they're still "going strong". If anything this only reinforces the fact that different plugs in the 5s make little or no difference. Copper plugs gnerate a better spark, but wear out faster than platinum plugs, that's why MR2s, both turbo and NA left the factory with platinum plugs. On the turbo with the boost cranked up you might want copper plugs to generate a stronger spark. But with teh 5s... hell you could have two piece of flint in there to ignite it and would perform about the same.

If your car is currently stock, then yes. If you're going to go turbo later, then you're going to want all fresh stuff anyway, so worry about it then.

Then why buy and use new plugs and wires in that time period? Just wait until you add the turbo.

ehh i guess..i just havnt ever changed those even since i got the car.

Just so you know those ARE IN FACT turbo plug wires. (Atleast what's pictured)

BTW, plugs are plugs. The only reason some recommend a certain brand is by quality or price. They will not enhance or hinder power unless they are faulty in that case they will hinder. The reason why so many recommend the coppers is cause they are dirt cheap.

^ not necessarily. low quality plugs can have higher resistance and actually hurt performance, amongst other things.

the reason people recommend coppers is that they make a better spark, not just 'cuz they're cheap.

ohh...then i gues i will change them when i put on the turbo.....ill stick with stock wires, but i will run some colder plugs. when i come around to that i will be asking you guys to help me choose what kind! lol.
