Time for new plugs, i read some things on here but then I went to sparkplugs.com and saw a lot of different ones which is the best or if you dont feel like looking at the link which should I buy. I do weekend drag racing with the car and not much more. I dont drive the car everyday.

im running ngk tr6 i like them alot i had the stock ones then went to tr55 ngk then when i used spray got me some tr6 they r good imo

Jbauer

what year is your car? I was about to run NGKs on my windsor 00 too but it had more threads.. a lot more threads thanthe head and a lot more threads than the old plug had. I took it the heck back and got some autolites, i wasn't risking a blow out.
I think the newer stangs 01.5+ have more threads on their heads though.

Motorcraft ASF32C copper plugs if you are NA.

NGK TR6 if you are FI.


Forget the exotic plugs.

More threads is BETTER.

Ford went to the plug with more threads to help prevent blowout.

Motorcraft ASF32C

I bellieve the 'F' means full length thread.

Jbauer

More threads may be better on a head that HAS more threads-i just did not feel comfy putting those NGKs in.
The NGK had 300% more thread than the autolites! i just don't feel they belong on a 99-00
