Hello, my name is Tom and i hav a 99 mustangand its time to change the spark plugs. Ive been lookin around and have been lookin around at diff. kinds. im prob. gone to get msd spark plug wires, but was just wonderin wat some1 elses thought was on the topic and ther personal experience with spark plugs.

Thanks. Tom

 

I won a set of the NGK Laser Iridiums on here and just put them in yesterday. I have the car torn down right now for a race tomorrow, so I can't tell you how they do, but I'll know tomorrow afternoon lol!!!

Just get standard platinums, Motorcraft or NGK, just don't get bosch, I've heard bad things.

 

Thanks, thats pretty much wat i wanted to know. ya let me know how u do!

 

I got screamn' demon coil pack with LiveWires and NGK TR-6

change your name, my name is Tom as well andI was here first...

 

I've heard very good things about those plugs and was going to get them myself soon.

 

Just replaced all mine with bosch, never heard a bad thing about them.

 

sorry but they are junk. the center electrode erodes away quickly on them causing misfires. i put them in alot of cars and every one of them wore out under 30,000 miles.

Autolite platinum AP 764 is a good plug and the double platinum APP 764 is good also. they will generally last 70,000 miles.
i like the Delco CopperR44LTS6's for NA cars and the Halo plug H-8 for forced induction or autolite 604's


cheap copper plugs are good too. the following are all great plugs for the 3.8

Well I personally have always had good luck with them then.

 

platinums suck the big one. autolite ftw

 

Mine came stock with platinums, so I'm not puting in coppers, ever.
