Ok first off I have a 98 cobra with a K&N drop in filter and a off road x-pipe and Mac cat back exhaust > I'm pretty sure the rest of the car is bone stock!
> I bought the car with a motor problem and had to tear the passanger head off to fix it > I reused the platinuim plugs and the FORD RACING plug wires that were on the motor when I put it back together .
The car Runs great!! but I changed the plugs to run a cooler plug so I can run my Nitrous kit . when I pulled the platinuim plugs out tonight the plugs were very Rusty colored EVERY PLUG WAS THE SAME COLOR ??? there was no major build up on the plugs but the color has me wondering whats up? I have run this car VERY hard (drag racing it > 7000 rpm shifts and so forth ) does anyone have any ideas as to why the are rusty colored ?? I do drive the car every day .

I have run Lucas octain booster in the car and probley every 3rd tank I run Lucas fuel injector valve and upper cylinder lube threw the motor . I guess that would explain the color !! I only swapped out the plugs to run a colder plug for my Nitrous kit > I want to go vette hunting in three weeks when I get a friday off and time to go back to the track !! > I should have my 3:73's in the car by then.

I would go with a minimum of 4.10's in a 4v 4.6 3.73's is not enough gear for a 4v


BTW the color of your plugs is normal
