For me I went with Autolite 24s which is one heat range colder then the stock 25s. And check the gap, I'm not going to say what I think they should be gaped for fear of being clowned by someone who knows exactly. But just google what the gap should be for a supercharged car.

i got autolite ap104's... they are platinum.
are there better plugs? i was kinda surprised they only came out to 27 and change.
like the mentally challenged person i am i forgot to get a gapper i must be drunk like >
im supercharged and the bog gets worse at low rpm's as the boost increases. the more boost, the shittier it runs.. should i still gap em at .35?

Sorry to thread jack!?! But would autolite 24s be cool on a rather stock 50?

what aftermarket? msd? yes. aftermarket internals? no.
its all cool sikwiditmke. as long as its about mustangs its cool.
EDIT: got autolite 24's.. i still have the autolite 104's. i took a 24 out of the box and it has half the threads on it compared to the 104 plug.. i think the 104 has the same number of threads as the plugs in the car right now. what should i do? i can upload pics of a plug from my car and the 2 sets i bought.
im really at a loss as what i should put in and i wont do anything until i can be sure im putting in the right parts.
thanks for the continued help

i have a s.c. 98 cobra, and I went with NGK TR6..worked really good. thinking bout going with the 7s this time around. you want to try to get the coldest plugs even if you have to change them out more often.

well yes and no to the heads. i have the 95 cobra so i think it has the gt40 heads. but whatever heads i have on the motor they are factory.
while im out today ill pick up some of those ngk plugs.. so it looks like im running lean... i guessed that by the feel of the motor and throttle response.
thanks for the help. does the plug look like it needs replacing?

I would replace them, then get a reputable dyno tune shop to tune it. the spark plugs should look like a grayish white and if it is it is running good
