bosches are ment for domestic cars, not imports. For imports, NGK and Denso Iridium are the way to go.

Iridium and platinum plugs are just a waste of money unless you're too lazy to change plugs or are running 300+ HP out of the engine. Come on guys, these are CELICAS! On average we're makin what 135 HP out of a GT? Get some copper Densos or NGKs for like $1.29 a piece and put them in the car. I guaruntee you you won't be able to tell any difference from those to an expensive iridium plug. As for plug wires, any of that "Autozone" brand crap, especially if there like painted wires and stuff aren't meant for performance. Just replace your OEM wires or like you said the NGK premium wires, but they won't provide any real gains.

Same goes for air filters, there is no difference between different brands for a stock air filter.

what causes the rotor to wear out un-evenly and fast..

this rotor was in for less then a 1000 miles???

Woah, dude, mine didn't look anything near that bad and I had it in for 100K!!!! Is moisture getting in there somehow? The photo makes it look like rust. Mine just had some white corrosion on it. Is the gasket intact around the distributor cap?

its not rust.. its like chared

engine idels smooth also.. dont know why it looks so bad and uneven

Where does one get a cap and rotor anyway? I only have a Pep Boys in town and don’t really trust them.

As far as plugs, I have always heard that iridium and platinum and all of those fancy ones are a waste. They are just coated copper and they corrode faster because they are coated. If you can find silver plugs, they are the best conductor and corrode much slower. I wonder if anyone makes silver rotors and caps?
