Bosch +4 or Iridium plugs?

[dannyboy1999]

Really which one would be the better plug? Ive heard good about both, i only have stock wires and coils for now but will get them changed in the future.

Both suck...

Bosch won't even go in my lawn mower they are junk and too expensive.

Iridium is just too expensive.

I suggest Motorcraft AGSF-32C @ .054 gap

So iridums flaw is its 28 bucks for 4...thats it? Heard it has one hell of a spark

Out of the two mentioned, I would go the iridium. Most people that have run Bosch in they're Stangs weren't too happy with them. not sure what brand of Iridium plugs you are talking about so it's hard to comment on them.

 

[Kilgore Trout]

Yes, my only problem with Iridium is the price.

Platinum is long lasting but has a cooler spark and is expensive.

Copper is hotter and super cheap but must be changed out every couple years.

Iridium is long lasting AND hot but costs a lot.

Sounds like Id go for the Iridium, Only the best for my stang. On the other hand Id put motorcraft in there and let ford do it, because I def dont want to replace a head due to having a sparkplug shoot out.

Motorcraft and Autolite plugs are the way to go on are cars.

 

[Kilgore Trout]

Autolite has short threads so I am going to disagree and say that the AGSF series of Motorcraft plugs are the only ones to go with.

Just stick with copper plugs if your mostly stock. dont waste your money

Still sounds like ill go with iridium, more bang for the buck last longer burn cleaner plus will help while i upgrade later. After im done with the 35th i have its on to the '66.

 

[dannyboy1999]

but on the other hand heard copper still gives the best performance too, just trying to sort out the rumors
